It’s a battery. It replaced the stock UPS battery I had. It fit, it plugged in correctly and seems to hold a charge. What else can you ask forOut of a battery that costs half of the name brand. Will it have the same lifespan, I don’t know
Bob B –
Great price- and they worked. Installed in an old UPS which supports my router, NAS, modems, and switches. So far so good after a few months and some brief power outages
Jarrett B. –
Fit’s in the bay and is of equal weight to the factory battery that came with the unit. Much cheaper than buying a whole new UPS!
R. KnowltonTop Contributor: Camping –
Two of these fit quite nicely in my CyberPower CP1500PFCLCD. The CyberPower CP1500PFCLCD has a stacking plate that goes between the two batteries (one battery is upside down on the other). Since the terminals on the new batteries were standard, everything fit together just fine. In fact, these new batteries didn’t fit as tightly into the UPS as the original batteries did, so they were easier to slide in. Battery life? They seem to provide the same run time as the original batts. Time will tell, I suppose.

I bought this to replace the batteries in my non-functioning Liftmaster gate. I ordered only one battery at first but it needs two to function. Gate works great now. Shop with confidence, these batteries are great!

Replaced old batteries in CyberPower 1100VA AVR which would completely shut off when main power glitched. UPS now stays on during main power glitches. Also replaced battery in a CyberPower 1000PFCLCD UPS with similar success. The old batteries were probably 6 -7 years old, hopefully these last as long.

Good product

Bought this to replace the battery in my CyberPower Model #SX550G. I can’t yet say anything on the Longevity of the battery. The terminals where laid out properly and the battery did fit in height and length However, it is half an inch wider than the stock battery because it does have a higher capacity than original. So, I just put the screws back into there respective holes fit the cover back on, wrapped duct tape around the unit just to hold the cover on, taped over any gaps so dirt and dust wouldn’t get in. Trimmed around any outlets that got covered and Voila, Back in business. Hope this helps. God Bless.

I used this for my child’s Razor dirt bike 350 (needed 2) and they work very well. The previous battery would die after 10 minutes and these batteries last a while. He usually rides a few times a day for 10 or 15 mins each time and it lasts a few days. I did price out a local battery store and it was much more expensive so this is a good price with speedy delivery.
Web Customer –
The crappy battery that came with my Yamaha Dolphin was a joke. After a 3rd use it wouldnt even take a charge. Replacement battery was nearly $200. The original battery would only last about 15 minutes of off and on use. This battery lasted 30 minutes or so and it still wasn’t drained. Just got tired of trying to kill it.
Alex –
Works
jdec112016w –
Has higher Ampere Hours than our original 1, which is absolutely great for our use. Had a few power outs since I put in new battery. Powers our alarm system, without any AC power for hours if needed, and enough power to activate 4 very loud custom built by me sounding sirens/horns, that can be heard from several blocks away, and still keeps our home protected!!

Although I was hesitant these batteries are working out great in my UPS! Just as good as the OEM batteries.

This battery replacement saved my monster speaker from being replaced! It was easy to install and fully charged. I installed it and was listening to my music immediately! It’s held it’s charge for days and I just recently charged it after 2 days of full use! Definitely recommend!
Web Customer –
It was easy to replace the original battery. Dimensions are the correct one. It died on me before a year of use. They have a 1 year warrantee, but you have to pay for the shipping. It is better to buy a new one for the price of the shipping.
Timothy B. Elliott –
I have a cyber power UPS whose battery has passed its prime. It was beeping and would not work. I bought this battery due to reviews. I swapped the battery, charged it and the UPS works like new. I was close to tossing the whole thing and this was a perfect replacement battery. I’m very happy with the purchase and saved me $100 from buying a new UPS.

Ordered 2. Received one that was made in Thailand as described in the product details for country of origin. Received a second one that was made in Malaysia. They are identical in model but the outer casing is slightly different indicating two different manufacturing plants. Just be careful ordering two you may get ones from different plants.

Bought for led flounder lights. I used one of them and it works great. Open the other battery after it sat in my home (68/72 degrees) still in the box for about 6 months and negative terminal was completely corroded to the point of having to use pliers to pull plastic cover from terminal.

Lisa D. –
I got this for my kids’ ride-on vehicle. The battery it came with only lasted about a year before it wouldn’t charge anymore (lasted 5 minutes after being fully charged). This works perfect for it! Hopefully it lasts longer than the old battery but so far it’s great.
Handyman –
I bought these batteries to replace the OEM that were old (5 years) for my Network UPS system. So far -since I installed last year- they are performing equal or better than the originals. They came with an even improved capacity of 9Ah over the ones replaced (7Ah) with the same size, so better performance and a lower price than the OEM. Great purchase. Recommended.
Lucas –
These seem like decent batteries. They hold voltage well. I will update this review if they give out after not too long. If this review is over a couple of years old, it heald up that long at least. Only concern I had is that I ordered 2, and one was from 2021 and one from 2022. Completely different packaging design and date printed on the unit. Since Im using them for the same single device, I dont love the idea of mixing them.

This Mighty Max M9-12 battery fit perfectly my CyberPower CP1000AVRLCD UPS. The battery came with a 100% charge. Easy installation: just remove 4 screws on the bottom access plate, pull out gently the old battery, using the protruding clear plastic tab. Disconnect the positive and negative wires, then pull out completely the old battery. Remove the clear plastic tab from the old battery and stick it onto the new battery. There is also a small piece of foam on the side. This is optional, but you may want to transfer it to the new battery, as well: the foam provides padding on the side so that the battery fits snuggly inside the UPS. Push gently the new battery back into the UPS unit. Reconnect the wires. Make sure the clear plastic tab is still accessible. Replace the access door and the 4 screws. That’s it! I can’t comment on longevity. The original battery lasted about seven years. I don’t know if I should expect the same longevity with this battery, but I hope it will extend my UPS’s life by quite a few years. Overall, good choice and installation was a breeze.

Used in a car battery jump starter. Have not used it for that but the jump starter has a 12v outlet which has been used a number of times. The battery seems to hold a charge as expected with adequate power. The previous battery lasted 6 years which is acceptable for lead acid chemistry.

Overall this battery is what it says and it seems to hold a charge well. I’m happy with my purchase.

Victor H. –
Working replacement for several of my Cyberpower brand UPS’s. Fit all of my 850AVR, 1000 PFCLCD and 1500PFCLCD models. I have replaced six total batteries across four UPS and they all see to work fine and at least initially have expected performance. I’ve tested power loss under load and they all work. These do not include new stickers for ease of sliding in and out during install and later replacement. Not a huge deal but would be nice if they were offered. The trick on install is trying not to stress the heavy gauge wires and aligning them. The stickers would help. Terminals fit very tightly as they should, and you may wish to use a small flat head to push the retention detent and not stress the wires or terminals. Overall construction seems as good as the variety of OEM batteries I found in my units as I replaced them.
John Tome –
UPDATE to 4-stars after AZ shipped a replacement that worked fine. Original: I’ve string trimmed our current property for the last 5 yrs and never had a problem with 7Ah batteries completing the task. My last battery was an 8Ah which also worked fine. This 9Ah battery goes dead with 20% left to trim.

Got this to replace the battery in my Monster Rockin Roller 2. It fits perfectly and works great. Great replacement at a cheap price. Now I don’t have to throw it out and can use it for backyard bbqs.
Bob –
Used as replacement for sealed AGM Lead acid battery for an UPS. (Replacing the OEM 12 year-old battery that was down to 50% capacity.) Fit into UPS, and positive/negative contact bars fit leads for UPS. Batteries can have different sized contact bars that can be individual product specific. This fit perfectly. Also, it was fully charged (100% capacity). Batteries can loose charge if stored by manufacturer or in a reseller’s warehouse too long. This was still fully charged, an indication that it had not been stored too long.

Peeled off the label on the old OEM APC branded battery to find specs and part number to cross reference battery for replacement. Perfect fit and easy peasy quick replacement access door in bottom slides right open with push on connectors and the OEM battery has a plastic safety shield that is just stuck on with adhesive and transferred to new battery. Hopefully this battery will last 7 years like the original ????

Batteries arrived sooner than expected. Excellent quality, easy to install.

I’ve had my monster rockin roller 3 for a while but haven’t used it so I guess the battery gave out so I bought this to replace it and it fits and works perfectly!! I don’t know how it’ll be in the long run but for now it saved me from throwing away a couple hundred dollar speaker!
SeaJay –
I live in a city where we tend to get bad thunderstorms off and on, meaning we have moments when our power shuts off. Last year lightning struck near my house and we had a power surge that destroyed our $400+ TV and our $200+ camera system. I found a battery backup that someone was throwing away, bought these batteries and our electronics have been safe ever since. These batteries last a really long period, and it’s because of these batteries along with our backup that we have not had to replace anything expensive. I would highly recommend.
Lamont Parker –
Good for what I’m using for
Molon Labe –
1st pair of batteries never arrived. Contacted the seller, they were lost somewhere in transit. Seller immediately shipped a new pair. Installed them in the UPS, perfect fit and work as well or better than the junk CyberPower provides with the UPS. Couldn’t be happier with the service and batteries
K. Kleinschmidt –
Buying batteries for large UPSs is always an adventure. Back in the day you could count on getting high-end batteries from the UPS manufacturer (at commensurately high prices) — but that’s no longer the case. So, finding decent, affordable batteries is the new challenge. I bought four of these, and each arrived fully charged, next day, at the proper voltage, and with no obviously bad cells. In my Cyberpower PR2200 rack-mount UPS, the batteries provide 55 V DC at infinite amps. When testing the UPS with a 600-W test load, everything works fine. These have become my new affordable standard for 12-V, 8- or 9-Ah batteries. No data about longevity, but so far, so good.
Eric –
Original battery on my ION Pathfinder 2 portable Bluetooth speaker no longer held a charge. Bought this battery as a replacement. Fits perfect and is compatible. Easy to remove old battery and install this replacement. It’s working great! Note: to access battery, need to remove the 14 screws holding on the large back cover. Once that cover is removed, it helps to hold the unit with battery facing down and lightly drop/tap the entire unit against a padded surface to get the battery out. Once out, disconnect the wires and connect to the new battery. My factory original battery was wrapped in thin foam tape to help cushion the battery. I had some thin adhesive foam tape so I taped the new battery the same and it fit in snug. Screw in all screws and good to go! Hope this helps. Added a few pictures for visual of unit.

Esplanadeviola –
Bought this for a UPS. Make sure you check the width of the connection prongs on your unit before you order any replacement battery! The two types differ by 1/32, so you want to get the correct width. Anyway, I did, and this battery installed easily and works fine.
Technologic80 –
I have this older (2015?) power supply that I use at my cabin for the internet router & security cameras. I replaced the batteries 5 years ago with a different brand, and they just went out. I ordered these to replace them. The last batteries I bought were glued together (because 2 of them are connected in parallel, and then slid into a compartment on the UPS). These were literally the 2 separate batteries, I used Duck tape to tape them together for ease of keeping the wires connected and sliding them into the battery compartment. The connectors seem well built; I had to bend them down a little to fit in the battery compartment and they were quite stiff. I powered on the UPS, and it had about a 75% charge from the box, so thats good. I let the UPS charge them for a while, and now it says I have 89 minutes of backup power with all my loads connected, so all in all, Im happy. If these fail or degrade unncessarily (remember – my last set of batteries lasted FIVE years so these aren’t being abused by any means), I will come back and edit my review. I promise!
Billy –
Installation is easy, took less than 10 mins to remove the old one and install the new one. It is pre-charged, ready to use. I didn’t give rating for the longevity, I have it for about 2weeks, working so far so good.
George Smith –
Battery charged with no issue and works fine
Debbie Kayser –
Was perfect
Soledad Berndt –
Fit perfectly and came fully charged. Bonus Points – the box fit perfectly into the compartment with the battery once I cut it down about an inch, so I was able to use that as a vibration dampener as the compartment is sealed with a foam gasket. This will double as an absorption pad if the battery ever leaks or corrodes.

Overall the battery was just what we needed. Was putting it in a Rockville Speaker and it does work. The only thing that was a little disappointing was the tabs in the speaker were smaller than the ones on the battery. Not sure if I didn’t read closely enough but it was supposed to be a direct fit I think. Battery works good though after I modified the wiring in the speaker with new connectors.

Inexpensive. I see the lead acid batteries have come way down in price since the intro of lithium for the same purpose. This one works well.
Nick’s Computer Guys –
Perfect replacement for my CyberPower 1500AV UPS. If you’ve never replaced UPS batteries before, read the directions carefully or watch a YouTube video. Also, when your first disconnect and pull the battery package out of the UPS, take photos showing the connections, especially the wiring between the two batteries. Remember, these are wired IN SERIES, which means the wires between batteries go to the opposite polarities, e.g. PLUS (+) to MINUS (-). If you’re careful you can reuse the heavy clear tape that holds the two batteries together, but you will probably have to replace the double-sided tape on the plastic piece that fits between the two batteries. Haven’t had any significant power failures to fully test, but UPS started up fine and after giving it time to charge shows full capacity.

Our Ion Block Rocker Max battery died. It still worked fine when plugged into a house receptacle…but it ain’t really a block rocker unless you can roll it outside to the street, a park, the beach, or other suitable venue. This new battery was a perfect fit replacement for the dead battery. Moreover, since fully charging the new battery in the unit, we have been using our Block Rocker for many hours on battery power alone (with the built-in party lights flashing to the beat the entire time); yet the battery status meter still shows the battery at almost a full charge! Excellent. The Block Rocks Again!
TheRevenant –
The item was just as described and arrived pretty quickly. The only thing I would change is that the size of the terminals is posted but I didn’t know there were different sizes so it probably wouldn’t have mattered for me but maybe will for someone else. I may have even overlooked that spec. I was unable to use this battery and my return window passed so I figure I can make it work in the future in a pinch by doing some creative wiring.
Mike B. –

My CyberPower LX1100g UPS would not stay on with loss of AC; but original batteries showed fully charged. I was concerned that the unit was no good and hesitated buying new batteries. But considering the original batteries Leoch djw12-7 were over 6 years old; they must be bad. The ML9-12 – 12 V 9 Ah is the same physical size as original with 9AH two amp hour more than original.

EDIT: Received warranty replacement 2-weeks after submitting request. I never received confirmation of the warranty request being received nor granted so I had to purchase another battery. Lo and behold, the warranty replacement came. Poor communication on their part but they honored the warranty so I’m pretty pleased. A bit of a hassle returning the new purchase which could’ve been avoided with communication. Purchased July 19, 2021. As of Feb 24, the battery is virtually dead despite very light use (discharged 5-6 times and kept on smart charger in climate controlled environment). Less than 6-months when previous brand last 30-months under same condition. Maybe I got a dud since it claims it has a 1-year warranty. Unfortunately, my call to their customer service yielded a email all details and proof of purchase to this address. I did all that and followed up several times and never received a reply. Be smarter than me and pass.

MightMax makes a decent battery and this one serves me well. I wish, however, that I was up to speed on small batteries like this and knew about LiFePO4 batteries. I would have spent the extra $ and bought the MightyMax LiFePO4 version of this battery. Either way, MightyMax is a good manufacturer to buy from.

My TrippLite Smart1000LCD stopped working after few years. After researching for what the issue is, I decided to replace the original battery with this one. The new battery fits perfectly. I power up and got it working again. However, my LCD screen on Tripplite is very dimmed even knob to control the brightness is at highest. It’s harder to see the voltage condition & batter status. Not sure if this is caused by the new battery or something else. Test successfully passed. I am happy. Will give this battery replacement the benefit of doubt. Time will tell how long it will last. 5 stars for now.

One of the batteries was faulty when received but without hesitation they sent a replacement! All working great now!

I put this in a Cyber Power as a replacement. I will dig up this review in a few years when it starts to get weak or fails and let you know about the longevity. I have two 1000 Cyber powers for PC, wifi and a monitor on the backups. We lose power about 5 to 10 times a year because there a lot of trees in the neighborhood. My UPS does get regular work so I will keep up with the review.

The terminal was wrong ( I need a screw on and these are spade. I had to jury rig it. That was my only complaint. Was $10 cheaper than the exact replacement.
Richard A. –
Used it on my vexilar. Works great!
J J Long –
I just installed this, so I don’t have much to go on yet. But it fit very nicely into my APC UPS and I’m hopeful it will give me some good future service so I can’t rate it on longevity.
Blair Brainard –
The battery only got 4 for easy to install because I had to get on my hands an knees and crawl under my desk to get the battery case to install it in the APC power backup for my computer. I should say the battery weighs about 10+ pounds. Now for longevity, the only thing I can say is that the previous battery lasted about 12-14 years. Hope this one does the same it has only been about 3 months so far.
W. Lamb –
I got this just to use as a bench power supply for 12V projects. It came with a good charge and is working well for this purpose.
Robert Snyder –
came fully charged just had to install it in my monster speaker it should fit all Bluetooth speakers or anything that uses 12 volt battery

It was half the price of local stores and works great bought for fish camera very happy with it charge lasted longer than friend with brand new camera and mine is 5 years old
AmazonShopper –
These worked in a 2 YO CyberPower 1350 VA UPS. OEM is 7 ah, these are 9 ah…I guess in theory…bigger is better…in any case, they work and my UPS is back on-line.
Renee –
Easy replacement for cyberpower unit
Mark Bean –
I bought this for an APC Back-Ups BN600G which was way past due for a battery replacement. After doing some research I leaned I could use this 9AH over the original 7AH and get even more backup time. My only regret is not getting these batteries sooner.
Web Customer –
The battery matched the description and worked great on my Monster 3 speaker. It holds a charge and works properly
LoganB –
These batteries worked for led strips for camping, will power led strips for days of camping. Also used in a speaker box for a replacement battery and it powers the speaker box better then before. recommended battery for any purpose
S. Thornburg –
It was almost fully charge upon arrival (above 90%). It fit perfectly into the UPS, and was easy to install. I like that it is 9Ah, a step up from the original 7Ah that was in the UPS… that’s approximately 28.5% more energy capacity, thus will provide longer run time during a power outage for what I plug into it.
tim amos –
Well it charges and works, not much else to report.
Robert Rose –
works great
Robert D. Hensley –
Replaced (2) batteries on Cyberpower 1350 AVR. Watched YouTube video from GuyCre8ive.com. Before you put the batteries in the case, turn on the power to make sure panel comes on and is not blinking. Turn off and install batteries into case
Honest Reviewer –
I use the batteries in my ups. They seem to hold a decent charge when new. When I unplug my ups from power, the ups will keep my monitor and computer running for 30 minutes. That’s is what the LCD panel says anyway. I never have tested it to see if I would get the full 30 minutes. Draining SLA batteries all the way is very bad for them. The bad thing is that after about a year or so they no longer hold a decent charge. I lost power the other day and they would only power the computer for about 1 minute. This happened last time I bought the batteries. However the batteries were not as pricey as some of the other places online.
Chris –
This 9AH battery has the same physical size ther 7AH. This works well in UPSs and other platforms
Don Carpenter –
Grandsons electric jeep never would last and had little power until I replaced it with this battery
Chris SewardjawjatekRoger O. ThornhilldarrylAaronJean-Paul CoteN.DavidLeigh McBainC. LeblancReg StranksMe –
not too sure if this was meant to be outside in the cold but works so far for a full 12 hour day of fishing haven’t killed it yet
Kevin –
This was purchased for as a replacement battery for my APC Pro 700 battery back-up. Fit perfectly just as the old one did.
Liz –
????????????????????????????????????☺️
RATE IT 4 U –
This is a good battery for the price. Works as expected in my UPS. Remember, you get what you pay for. If you go too cheap on a battery replacement, you will just pay for it later. This battery is a good one.
Woodness –
Charged it on arrival, and it has worked since. Time will tell on reliability, durability, and long life. My old Rayovac lasted years.
Carey J. Boyer –
Great Replacement Battery !!!! Fit perfectly, working great !!!!! would recommend !!!!
F. Hawkins –
Works like a charm. Easy to install.
Joe –
Small compact cell
K Tian –
Battery life is pretty good
Noreen –
I needed to replace the battery in the UPS for my computer. This was a good physical fit with greater Amp-Hrs. so it was perfect and works perfectly.
TX Homeschooler –
Batteries are the right size for my UPS and have sturdy connections. The four-pack was a good value for my four dead UPS.
Curtis –
Works well..
William Fulcher –
Replaced the battery in my cub cadet zero turn mower with this one. Had plenty of cranking amps to fire my mower right up. I can’t speak to longevity because I only used it for the end of one season. But I imagine it’ll last about like any 12 V battery replacement.
Web Customer –
The batteries fit my old UPS perfectly and work great
dale rogers –
worked great
Jack –
Arrived well packaged and with the correct F2 terminals. The battery is 9 Ah instead of the usual 7 Ah, which equates to extra battery capacity. I can’t comment on battery life since I have not used this brand before, but hopefully it will last several years.
John –
They work very well
Trevor Brown –
I’m giving this product a 3 star because time will tell. I installed them in my daughter’s razor pocket mod and it works flawless again so this is a plus. Time will tell how they hold up.
Chris SewardjawjatekRoger O. ThornhilldarrylAaronJean-Paul CoteN.DavidLeigh McBainC. LeblancReg StranksMe –
Replaced the battery in an APC UPS as this is the same capacity and physical size as the original.
THOMAS M PFEIFFER –
Works for what I needed it for! Will buy again.
aponumberone –
I’m happy with this battery I replaced the battery in my Monster Rocking Roller 3 speaker when it would no longer hold a charge after 3 years for the value I will be happy if I can get another 3 years out of this battery. It came quickly in the mail with no Damage. I’d recommend if you need this size
Charles B –
Worked just fine for less money than the “named Brand” battery!!
Sterling S. –
So far so good they replaced my scooter batteries the fit was fine easy to install.
G J M –
Works perfect for a camping battery box that I built for recharging phones and cameras.
Troy –
Fit in my UPS and seems to work. Haven’t had an outage so can’t comment on power or longevity.
Todd S –
I put all 12 in two APC Backups Pro 1500 UPS, both with the add on battery pack. Despite there being no SKU to replace the batteries in the add on battery, it is trivial to swap them.
Mathias Speed –
Very good so far. Don’t know how long it will last under normal use
Victor Martinez –
The price was reasonable great product
JKocher –
This battery is a drop in replacement for the battery that eventually died of old age in my APC Back-UPS 600.
Anthony M. –
Using the battree’s in a nifty battree mount that I made for my mini bike. They seem to hold up great to the abuse.
Cata Arecibo –
I was about to throw away my Triplite UPS which cost me $129 back in the day. I then thought there might be a way to replace the battery and I found it. This product was easy to install, matched perfectly to my UPS and does its job well. I’m a happy customer.
manwithplan05 –
I’m using this battery to power a game camera, along with a solar panel, and a charge controller. I put the battery and the charge controller inside a waterproof, plastic electrical box. It’s working perfectly!
Rodger –
Worked on my cyberpower ups.
The Reeds –
Use this in my pickleball machine. They don’t last long. But luckily they aren’t too much. Never had to replace the battery in my tennis ball machine. I don’t know why these don’t last longer.
M-J –
I can’t rate the longevity yet but they were a perfect fit, worked as expected and the seller was great with communicating with me. I have every reason the believe these will last as expected.
Joe Houston –
The battery seem ok from brand new but I just don’t know how long it last initial the v is about 12.86 when first start or test time will tell that why four stars now but the price is definitely more friendly than the other brand
Lew –
I bought this for my 170 cc go kart. I keep it charged with a trickle charger and it has performed great the last few months.
Barkinmarmot –
This fit perfectly in my old UPS backup from Circuit City and has been working with problems since install. Very satisfied with this battery.
Rafael Z. –
Reliable product.
jimmy –
1 month In and no issues the batteries hold a charge and we haven’t had any problems. Delivery took awhile but they work nonetheless.
Dwayne Adams –
Replacement batt for my RocknRoller4 portable speaker, it worked perfectly. i would recommend this product
Autobahn97 –
Purchased to replace a spent battery in APC brand Back UPS 600 and it fit OK and seems to work well so far. I have purchased a few batteries from Mighty Max for small APC UPSs and they seem to work OK and cost less than the APC brand.
Carol Wright –
It did the job.
Web Customer –
Good battery
Allows real reviews –
Used for our kids razor quad
Greg Dana –
Used battery for a homemade scooter worked great
Number1 –
Good Battery Replacement for my UPS. It’s held up during short power outages.
VRGuidry –
All of the sudden. Kids electric jeep (12v), 4wheeler (24v), and Portable radio (12v) all went dead in a matter of a week. I replaced the batteries in all with this brand. Seemed to be a good price and has not let me down yet.
Mark A Niemann –
replaced old battery
Marshall –
Came in good packaging, perfect fit for my Cyberpower 1500va ups. It took me about 5 minutes to swap them out. So, far I’m very satisfied with my purchase.
Lac –
These are hit or miss for me. Purchased several over a few months and some are still going, some died and some are barely limping. Looking for a different brand.
Cody Gatlin –
Horrible life span. Had great performance for the first 3 months. Soon after that the batteries died in half time and now down to no time.
J Lopez –
Easy to install right fit no issues
Jason –
I cannot speak for the longevity of these batteries since I just got them but they are good replacement UPS batteries. I have used other MightyMax batteries in the past for other backup applications and have had good luck with them. They seem to provide good run times. They were packaged well and shipped quickly.
Joe –
Second time I ordered this battery and second time it failed in less than a year without any support from manufacturer. No more.
Arnold –
Needed to replace the battery in the generator so I could sell it completely up and running. We had never used the generator and was glad to sell it off to someone who needed it. Battery is working great and the old one ended up still working just fine. I am happy with the experience with this battery.
Dave Pearce –
Not exactly what I was looking for which I appreciate. These batteries usually last about a year so we’ll see.
Web Customer –
Just received it. Install easily. Worked when I installed it.
Gerald L. –
Used this battery to replace a rechargeable battery in a Samson XP 106. This was a little larger since the capacity was larger. This would be as big as you could get as a replacement. Any bigger and it would no be usable. But works fine. I did have to get some step-down adapters (F2 to F1) for the terminals too…just FYI
Dean –
I purchase this two pack for a tripplite UPS and they usually last me about 4 years before I need to change them back out.
Chris SewardjawjatekRoger O. ThornhilldarrylAaronJean-Paul CoteN.DavidLeigh McBainC. LeblancReg StranksMe –
Battery seems to work well and was a proper fit, so good product.
Annabel Cantrell –
Easy to install and I am not good with electronics. Ran for hours, we took it on a walk on the bike path (we walked, my son cruised LOL) and we had no issues using it there for over a mile (45 mins) and then that evening for a couple hours at a friends. Definitely recommend.
Jay D. –
I replaced a 7Ah battery with this 9Ah battery. They were the same size. I am very satisfied with both the battery and the price 🙂
MTS Support –
I have never been disappointed with these batteries.
I’d Rather Be Fishing –
Quick ship, perfect fit, fully charged. Time will tell…..
ATRAIN –
Fit my Monster Rockin Roller 4 Bluetooth Speaker perfectly and was very easy to install. i added a little self-adhesive foam to the outside of the battery to get reduce vibrations with a very secure fit. The battery was half the price of those at my local battery store. I can’t speak to the longevity yet, but if it lasts 2 years, I’ll be very happy.
Carol and David Melvin –
Replaced the battery in my ups, but the ups itself was faulty
Steve –
Fits in the ecox gear Bluetooth speaker from Costco. Lasts forever on a charge now
Paul –
I replaced a battery from one of my Cyberpower UPS, works great and the software can now see the battery is 100%
J. Myers –
This battery ‘s body (not clips) is 2mm taller and about 1mm wider than the Leoch brand version used in factory CyberPower 1500 UPS Power Supplies. The inside plastic of the 1500 has an extremely tight tolerance. So the MightyMax fits in the upper compartment, but wedges when crammed into the lower compartment, due to its excessive size. It’s a total bear to get out, you have to take the upper battery out first, then manually stretch the plastic body while holding it upside down, and having someone else winkle the battery out. Also you maybe can’t use the clear white plastic protector on the positive + red terminal, as that scrapes the ceiling and wedges it further. And you have to shave down the inside plastic on the 1500 if you ever want to get the battery out again in 3-5 years. I wish Mighty Max would build a 9AH battery that was 2mm shorter. The easiest way to do this is to take out the three tabs on the upper left of the lower compartment, which are serving to hold the black power wire in place. Move the black wire to the right, and tape it. A jigsaw with a 6 blade would probably work best, but a carpenter’s reciprocating saw works wonders on the first two tabs. The third inside one can be snapped off with a 12-nominal 16 flat-blade screwdriver, then reworked with an X-acto knive. Remember that the battery normally sticks out about a half inch even when it’s hitting the back, as the cover has loft in the front. With two hours of labor, you too can save maybe $5!
Harry J. –
Good value
Chris SewardjawjatekRoger O. ThornhilldarrylAaronJean-Paul CoteN.DavidLeigh McBainC. LeblancReg StranksMe –
I had a UPS with a screen that started flashing. Did some research and most people agreed it was a battery issue. The official replacement was 1/2 the cost of just replaceing the old unit. Which is crazy. Lucky enough. This fit and it’s been working solid. I’ll purchase more as my other UPS needs to be replaced.
Chris SewardjawjatekRoger O. ThornhilldarrylAaronJean-Paul CoteN.DavidLeigh McBainC. LeblancReg StranksMe –
Had to resize the terminals
M. Swanby –
I bought this battery to replace a battery in my deer feeder. This battery fit perfectly and has been working without any problems. I would buy this battery again when I need a battery for my deer feeder.
Thomas Pike –
I used this battery to replace the one in my Verizon FIOS box. No more beeping alarms and much cheaper than buying one from Verizon.
Jack Spade –
I’ve installed this in my Cyberpower UPS and so far it seems to be doing well. No issues and I’ve run the self test on the unit a few times and it always passes. Model BRG850AVRLCD.
Linda L. –
had to drill the holes out and straighten the poles for it to fit. It does work just fine.
Chris SewardjawjatekRoger O. ThornhilldarrylAaronJean-Paul CoteN.DavidLeigh McBainC. LeblancReg StranksMe –
After two weeks, it still works fine.
I.P. –
Used the batteries to replace old ones in a APC 700 UPS system. The two batteries fit well.
Colin McConnell –
Replaced old batteries exactly. Work fine, took a charge, UPS tested them and found them working 100%.
Janice –
Powers my Humminbird Helix 5 all day. Fits my Yak Attak cell block perfectly.
fredericksen –
Best price and works better than ones that cost triple the price.
Albatross –
Instead of purchasing a new UPS, I just replaced the battery. Easy to install and tested good (after charge). Will see how it performs over time (only installed for 2 months). Update to follow.
El Guapo –
Replaced battery on my Ion Party Blocker. So far so good!
Richard Finger –
Very much like this product! Highly recommend!!
e west –
i have an older APC es 550. the battery in it went bad. this is working fine as a replacement.
Larry –
I use this battery in a battery back up unit for my computer. Space in the battery compartment is very limited, but this battery fit just perfectly. It’s been working fine, no issues at all. I haven’t had it long enough to rate the Longevity yet.
Dave V. –
Just installed 3 weeks ago so do not know how long it will last. Very pleased with this purchase.
allen –
Great battery and long-lasting
brooke wallace –
Work well. Stay charged for a while depending on the size/weight of the ride on its powering
B. L. –
Straight to our door, plugged it in, and kiddo used the powerwheels Dora Jeep for about 30-40 minutes. Did not run the battery all the way down, currently charging. So far works great. If any issues, i’ll come back and change my rating but for now, the kiddo is super happy to have her jeep running again.
chansen4 –
Worked great
Joseph M.nubkcugggnbbnj –

I got this battery’s for my scooter and works very good so far. Drained and recharge about six times already and still working good.
Ferris M –
Worked as predicted
Alex Zamora –
My rock roller 2 from monster would not hold a charge anymore at all and this was the basically the direct replacement for the battery it originally came with. Just a few minutes removing screws and was easy.
Brandie C Howard –
My speaker is like new now! Such an easy fix!
Erik –
Popped right in and was ready to go. Back to normal operations and battery test passed
TSG –
I thought this was gonna be an exact fit for my CyberPower UPS, but I didn’t measure beforehand… then found out these are a couple mm too long to fit properly. The problem was easily solved by sanding down some interior plastic. While tight, these now fit fine. They provide the expected run time for my equipment, and allowed me to get a few more years from this UPS. Mission accomplished.
Thomas G. –
only had the batteries installed for a few days so far. but they seem to be providing better power reserves than the original batteries so far.
raggedynan –
Exactly what was needed for my Monster Rockin’ Roller speaker. Provides over 100 hours on a full charge!
Paul –
Works great just like original
Guitarsjoe –
This battery fit my backup system perfectly. APC 500. Will check back in a few years to update the longevity
Brad –
I had issues with one of the batteries out of the two I purchased from this company. Because of the type of battery it couldn’t be returned. I worked with their customer support and they corrected the issue by refunding my money for the one bad battery. It surprised me how responsive they were to my needs. I would buy from this company in the future because of there good customer support.
john l pellet –
As described. Replaced batter in APC BE750G & just worked.
DJ Sandberg –
I bought this battery to run a linear actuator in a greenhouse. It’s been running for 5 months and I still haven’t had to recharge it yet. It’s a great battery and really holds it’s charge.
Bob –
I live in South Florida where out power is generally consistent. However during the summer months we get a lot of rain and thunderstorms. With those rains, come all too frequent momentary power outages that last just a second or two – just enough to reset your computer. In addition to having several UPS’s to protects my computers, I also use one to back up power to my cable modem and router. This way, if we have a momentary power glitch, my PCs as well as my modem and router stay alive, and I avoid the several minutes it would take for the cable modem to fully restart. I have used Mighty Max batteries to replace worn out batteries in my UPS’s for quite a long time. They are easy to install, work great and seem to function as well as the original batteries. Plus the price is definitely right….I highly recommend them!
Bob –
Fits perfectly. Working great so far. No problems
idkist –
Perfect replacement for our electric car. Plus it’s the same form factor with 2 extra Ah over the stock battery so it lasts slightly longer which only adds to the enjoyment
Ernest Ramirez –
So far so good!! It fit perfectly for my Rockin Roller 4. The battery came drained, and at 1st I was bummed thinking the battery wasn’t going to work. After fully charging the battery 1.5 hours later (which isn’t bad btw), now my speaker is once again portable! So far I have used the speaker for 3 hours, and it still shows a full battery. Nice!!!
Salvador Arana –
Comparable with the required voltage. GREAT deal.
WKU1990 –
Works perfectly in my old APC 500 UPS. I use the UPS for my TV, cable box, and Fire stick.
jesse –
Great battery replacement for my monster rolling rocker 3 . Last better than the one that came with the unit. Last days without a beat . Great item thanks .
Marvin –
This fits the bit smaller amp hr. battery box perfectly. However the male electrical connections are a bit wider than on the stealth cam battery and needed to be trimmed to fit.
Techmeister –
This is a standard size battery that fits most UPS from CyberPower and APC. The cost savings is substantial. On some CyberPower UPS’ you need to save the tape and wires from the UPS when you swap the batteries out. Other UPS simply remove the old batteries and put the new ones in. I have used these batteries on many different UPS’s and they seem to have the longest lifespan (typically 3+ years) and they also have more power (9AH vs. 7 or 8AH) than the originals in the same space/form factor.
My10sense –
Can’t even remember when I got this grass trimmer–it was a bonus when I bought a mower. Anyway, it was sometime between NiCads and Li Ion batteries for these tools. Works fine now, although Li-Ion batteries would yield better performance for the weight.
Ricky Leyva –
Good product.
david littrell –
Batteries were fine but not what I needed and can’t return them?
MovieBluff –
Perfect replacement for the CyberPower CP1000PFCLCD PFC Sinewave UPS I bought in 2016. Fitment, terminals, etc. was totally fine for a better price than the Cyberpower batteries. Also bought two more of these recently to replace the batteries in my Liftmaster gate opener. They were a little bigger than the original 8Ah batteries, but fit inside the housing and the gate is working as good as new. The larger battery should give more opens/closes in the event of a power outage.
Capt Lou –
Recently installed, but so far is working fine
Jorge guerrero –
Muy fácil de instalar y muy buen tiempo de uso con una sola carga
bigjim –
Great set of batteries to replace the OEM APCRBC161 battery pack that dumped at 6 months. Simply pull off the cover and jumper from the overpriced OEM stuff and place them in the same orientation on the new ones.
Franky D. –
It’s going on 2 months and the battery seems to be doing it’s job. No problems charging or holding it’s charge. So far, I’d call it a good purchase

Works perfectly and fits just right on my Rockville RAM speaker. Lasts about 4 hours at full 800 watts of power.

I thought I had to get me a new portable Bluetooth speaker from Sam’s club/monster rocking roller. It was not charging and pulsating. Glad I didn’t. This battery fixed my problem. Back to jamming out. Saved me money.

Received what I ordered. Seller provided a better price than expected.
Fran??ois –
Worked perfectly, and have a good capacity of charge.

I have a Cyberpower ups that stopped working. It was clear that the issue was the battery. I chose this one as a a replacement, and it works perfectly. It replaced the OEM one at a significantly reduced cost. Highly recommended!

Ion Rocker wouldn’t hold a charge. Looked online and found out that replacing the battery is an easy fix. Purchased this battery and installed. Ion Rocker working like normal.
Apolls Mommi –
Bought this for my husband because his old one wasn’t holding a charge. He uses this battery for his fish finder. He said it was worth my money because he didn’t lose any charge after four hours on the water…

Love these batteries! Use them for lighting and electronics out ice fishing and have never failed me

I use these all the time for my razor kids rides. always work and last
Web Customer –

I have ordered these batteries several times over the years for my UPS units and have not had any issues. I use a multimeter and resister to test them and they all test good. Packaging is great. Each one is individually boxed with terminal protection so there are no issues in shipping no matter how poorly the package is handled.
David Bean –
I have barely used this battery. And had it connected to a 12 Vdc switch panel which allowed me to turn off all loads to the battery. And it was working great then the battery discharged and was leaking something from the top around the edges that appears to be acid. I charged it back up with an automatic 12 Vdc battery charger/ maintainer and battery still functions but is still leaching acid out the edges on top. I like the battery except for the fact that apparently it is not staying sealed.
teresa –
Worked perfectly. Fast delivery. Very satisfied

It is working as intended to run my lowrance 5 reveal fish finder on my kayak
MrFastFox666 –
I bought this battery to use as a dash cam battery in my car. I tested it first by fully charging it (it was pretty well charged when I got it, at like 13v), then discharging it to about 11.5v at 0.6A. The charger reported a capacity of 7.9 Ah, so it seems like you could get the advertised 9Ah at 0.6A if you discharged to 10.5v. There’s a datasheet on their website with more info. As for longevity, who knows. Mine will be in a hot car and will be cycled constantly, so it may not last very long. In a more traditional setup, it may last for a good number of years, but I have no way of knowing this. I’ll post updates if something happens. So far I’m super happy.
Bran Solo –
Bought for my security system. So far so good.
Luther S. –
Yes , I like it, because it has more Amh than my old one , although it is still good so I have a backup, It works well in my Solar Fence Charger, the Terminals was wider than my connectors so I filed the prongs down so my wires would fit, I did that so I could Interchange with my old battery. Now I have two batteries that work!!!
Joe Schaible –
I repaired my UPS with this battery
Brian Arnold –
Kind of frustrating to have to purchase a 4 pack but a spare i guess does not hurt. The only flaw was getting one that was leaking out of the box. I reported it and a replacement was sent. Good job. It replaced a three cell 1500 cyberpower unit. Supporting and functioning as designed without error.
[email protected] –
Overall great. Will try to update when applicable.. great lil battery, 9ah oh yea.. cheap af and completely charged no issues. On a 30a solar charge setup and its been doing great! Think im on week 3 in AZ(outside in 90ish air temp and enclosed obviously).

Cheap battery works but doesn’t seem to last very long. Bought new batteries and new charger. Don’t know which is the culprit. But cheaper than the in town option

Great Battery at Fantastic price point

Bought this to replace the batter on my ION Block rocker Max. It was easy to swap and shows full battery life in my block rocker. It was only allowing me to play music on it while it was plugged in.

Newcar67 –
I count on my CyberPower battery backup to protect my desktop computer during storms and sudden power outages. After 5 or 6 years, the original battery recently failed, so I looked for a quality battery at a reasonable price and found the Mighty Max Battery with plenty of good reviews. I bought it, and it fit perfectly. I can’t comment on longevity because it’s only been a couple months since I installed it and I’m looking for 5+ years for a typical life for these batteries. It seems good, it fits and it supports my computer so I can manually shut it down for maximum protection in a power failure. I recommend this battery.
Sherwyn Stephen –
My 3-year old has a ride-on fire truck and after a while, the original 12V 7AH battery wouldn’t even last 15 minutes, even after a full nights’ charge. I installed this battery and I could tell an IMMEDIATE difference. An hour of riding in the neighborhood, up and down hills, and the battery was still going strong. Would definitely recommend, especially since it has the same dimensions as the original battery, but has 2Ah more.
Mark Ambrose –
Too new to say much

It’s a perfect replacement for my Razor E300 batteries. Same case size, voltage, higher amperage compared to the dead OEM batteries. Thanks to Kimberly who is a great representative. She’s very professional in dealing with the customer. I’m buying again in the future. Highly recommended.
Sam –
Battery is doing well for what I need it to do.
Gwen –
Great buy works great for my vexilar
Kenneth Pickens –
Worked right out of the box. Was much cheaper to purchase this replacement battery for my daughter’s Jeep and just connect the old wires to it than to spend $70 on the exact same product with wires pre-attached.
Mary Hanneman –
Easy to install and works well, but only for 13 months to backup Verizon Fios. Had minimum very short power outages. So, battery only was used to actually backup for a very short time.
paula bricker –
Battery is fine. I thought I had ordered a 12aH and received a 9ah. Either way the battery works
Pupqy –
Took 5 minutes to swap batteries in CP1350AVRLCD. I noticed after the fact that it says in listing NOT TO INSTALL UPSIDE DOWN but in the battery back up that’s how the stock batteries were installed so hopefully they wont leak!
Francisco J. Ortiz –
Notice how Batteries for a UPS cost almost as much as a NEW UPS? Well these batteries seem to be a great fit for a reasonable price compared to buying in a store. By the way this particular model has the spades that are 1/4in wide.
Chris –
Easy to install in my APC Back-UPS 550. I purchased it to replace the factory battery and it has worked flawlessly. The software provided by APC showed the battery arrived at 70% charge. I left the UPS plugged in without anything connected until it reached 100%. The battery has been used a few times during power outages and continues to provide the appropriate back up power months later.
Tethyss –
Cheap and functional, replaced the old batteries in my Cyberpower UPS. Working great so far after a couple of months. Perfect fit.
Craig S. –
Works as expected for 2/3 the price. Will see if longevity is the same, but for now I am more than satisfied.
Jean Marie Kolinofsky –
This battery is used for our back-up system from Verizon. It was an excellent value and arrived very quickly.

Fit my Cyberpower EC850LCD UPS perfectly. Was 86% charge capacity as delivered but seems to be charging up nicely.
Matthew S. DeVuyst –
Use this for my ice fishing flasher fish finder. Fit perfectly in my set up and provides all the power I needed to fish several days without needing a recharge.
Angela –
It brought my old backup power back to life. I would definitely recommend it.
Stacey Craig –
Came as described. Plenty of power. Will comment on how long the product last in a year. I will charge it on a trickle charger as needed.
Mo W. –
My UPS battery was ruined during a 4-day power outage. This brought my UPS back to life for a fraction of the cost of a new one. Very satisfied.
keith g heil –
Worked fine
Joel Jones –
Bought this battery to breath life into decade old a long dead CyberPower 1000 AVR. Installation was simple, terminals fit just fine for this application. Have been using it for a couple months and no signs of issues, bulging, or heat buildup. Has provided ability to give plenty of runtime to shut down my PC this past winter with several power outages occurring. Would recommend this in the future.
G. T. –
Used to replace battery in my portable air pump. I used it immediately after installing in pump and it worked just fine.

Had an issue with the battery shortly after the return period ended. Wrote a brief email to the manufacturer/importer (Mighty Max Battery) and they provided stellar customer support. Very quick response and thoroughly addressed my issue with minimal fuss. Excellent knowing they stand behind their products.
Juan G. –
Great price and seems to be good quality

Super easy to replace, but the battery is already in need of replacement after only 18 months in my FIOS ONT. I expect 3-5 years out of a battery like this and only got half that.

CDP’s Onceagain habit of purchasingTop Contributor: Guitars –
After several years my Uninterrupted Power Supply Surge protection needed a new 9Ah battery and this was available for 21$ so I gave it a try fit easily into UPS and almost to full charge and after a while I checked and it was showing it was fully charged and 100%. So far so good.
mwajac –
Good battery life, fair price
Howard J. De Pol –
Very good quality

Product was used to replace batteries on a stairlift. don’t know about it’s longevity until it last’s about the length of the batteries that were replaced.
Justin –
Bottom line up front: My testing indicated only 7AH, not 9AH. However, for the price paid, I’ll keep it. That is, one could pay a premium price for a premium battery, or get one at a bargain price, but one should not expect the same performance. My feeling this battery is offered at a bargain price. My tests: In order to evaluate this product after it seemed to not last as long in a UPS unit as I had hoped, I calculated the Watts expected from a 9AH battery (@2X12 = 24 Volts DC X 9 Amps Hours) and connected it straight to a 10 Watt DC load, expecting to see about 21 hours of run time (after more than enough time charging to be fully charged). This battery dropped voltage significantly at 75 % of that time (20 Volts, then soon after to 11 Volts). Recalculating using a factor 7AH power gave me exactly 100% of expected run time. So, my expecting to replace a 7AH battery with an exact size match replacement battery for the dead batteries that I pulled out of my UPS with new technology? 9AH powered battery now seems like a marketing gimmick to me. However, considering the price I paid, the hassle of returning it (to be fair, I spoke to the supplier about my results and they had no problem with me returning them, and they seemed very helpful in that regard, but they had no interest in my evaluation), to tell you the truth I’m going to be satisfied with at 7AH battery, because I really have no idea of where to get a premium battery without spending more money and I can’t see that it would be worth it having already taken delivery. My point in testing was to make sure the batteries were not junk, and my tests indicate they are not, but I’m not giving high marks when they do not deliver as advertised.
Eric P. –
I checked many reviews of this and other products to make sure I got the right terminals. It appeared this was the most sure F2 terminal battery replacement, but I was very disappointed to have received F1. The battery still seems ok otherwise and I ended up building my own adapter cables as the connectors for my UPS slip off these smaller F1 terminals. I plan to report on longevity later.
Pedro Agosto –
nice battery for the money
jabari –
I have a portable Rockin stereo that required a battery replacement. Seems like the battery went out after 2ys of use. The battery I removed was very descriptive, so I knew exactly what to purchase. The costs was better than the local stores. Hopefully I can get a few years out of it!
Web Customer –
Everything was great except the first one was leaking but sent the other one and was great
Gary E –
Deliverd quickly, generic product, nothing to say, just hope it lasts as long as they claim.
Mike Oxlong –
Bought these at a great price, they last a pretty long time and the power is perfect.

I liked the higher 9 ah capacity in the same OEM size. Easy upgrade in a battery replacement for my phone’s Fios battery backup power supply. We shall see how well it holds up.
Tansey –
I replaced the battery on my generator. It started right up. I will update the post if I have issues later.

This battery is really good. It last a long time to die on my speaker at max. It was easy to install just clip on positive and negative.

Don’t wait for 3 years to replace the old batteries. The old ones swelled and broke the UPS cavity. Reuse the original jumper wires

Works good so far.

I bought two of these batteries to replace the batteries in a Cyberpower battery backup. The price was great and the batteries are exact replacements. I’ll update this review once I have more than 7 months of use out of them, but so far they have functioned perfectly during several power outages.

I liked how it was easy to install as well as having a new battery but it gave out less than a year lated. Ended up buying a whole new speaker.

Purchased this as a replacement battery for my sons 12v ride on atv. This battery blows the original out of the water in terms of lasting time. Great price. Have had it for a few months now and it works just as well as it did on day one. Will be purchasing another as a back up battery and another replacement battery for his ride on jeep come spring time.

Lasts long.

Perfect size replacement rechargeable battery for my home alarm system, at a lower price than my previous battery with 50% more capacity. Time will tell how long it will last.
C. M. Vining –
I needed a new battery or one of my UPSs but the first one was totally discharged on arrival and would neither charge while in the UPS nor charge from an external 1,000 mAH charger. Fortunately, the second battery in the shipment seemed to work well. Only time will tell.
Tom Denham –
So far the battery is working great! Love it!
Dustin Moneymaker –
I am using this on a custom charge box i built for a portable electric fence. they hold plenty of charge for what i need and seem to charge well with my solar panels. i will say they are lacking performance in the cold weather but so does almost every other battery.
EJL –
I used this battery for camping with a solar power charger. That worked fine for my needs. The battery then sat in the garage for the next 4 months, still attached to the solar charger, but not enough ambient light to trickle charge. It got down to 6V and is no longer working. Had it tested at a shop and was bad. Lesson learned. Make sure you keep a trickle charge on it if you aren’t going to use it for an extended amount of time.

Battery fit the UPS like a glove and got it back on line. Replacement took some effort, but not the fault of the battery.

Easy to install!

I am using these to revive APC Back-UPS ES 550 battery backups, which are absolute workhorses. They’ll run forever, just keep feeding them batteries every 1-2 years. This battery is an exact replacement in size, voltage, amp hours and terminal type. I’ve had no issues with this replacement battery.
Lckflyer –
Great battery with lots of power. Just keep them plugged in they last longer. Left dead they die pretty quick.
Just1dude –
Perfect fit. Good value for the price.
MIGUEL DARZE –
3rd time I buy this product and don’t regret. Lots of power to my kids toys.
Parker Sniffen –
Shipped within 48 hours. Physical dimensions were accurate, fit my APC BE500U backup power supply perfectly. Terminals were F2 (.25) as specified. Arrived with 9.28v charge, a bit low considering label warned against allowing voltage to dip below 10.5v (under load), however device powered on and self-test was successful. I did not check for a manufacture date…but a paper insert in the package offered a 3-month extension of warranty with registration.

Great price purchased for power wheel kids car. Original battery was over $90. I took the adapter from the old power wheel battery and used some clips. Works perfect.

I like batteries.

Fit perfectly in my UPS. Will hold off on their performance until more time has elapsed. (It’s only been a day since received.) Shipping could have been faster as it took >14 days to arrive in upstate NY from NJ!

Great replacement battery, took less than 5 mins to replace. Charging perfect ????????

My child’s ride on vehicle came with a 12V 4.5Ah battery, but the slot was large enough to accept a larger battery, this 12V 9Ah battery dropped right in a connected easily. Doubling the range on the ride on in a 5 minute swap out job.

Excellent replacement for gate opener. Has that little bit of extra juice you need in a gate opener. You will need to replace the connector on device as the battery connection tabs are larger than defaults.

Battery came nearly fully charged(12.5v) and when connected to a charger it charged the rest of the way within an hour to full. I’m using this to power my Garmin Stricker plus 4cv fish finder and it worked without issue.
Dr. Kevin Folta –
I have this battery hooked up to a single solar panel and charge regulator. It powers about 28 W of high output LEDs used for lighting a chicken coop. For a small battery it is up to the task and performs better than my larger rechargeables, at least over the first 30 cycles!

my UPS came back to life after replacing the batteries with these. The original batteries where 7Ah and Mighty Max were 9Ah giving me a little upgrade.

Good battery but does not fit my ups back up unit. I’m going to add it in parallel to the ups unit .
Mike B –
Price seems to be a to good to be true because of the price. On arrival voltage was 12.92 VDC; healthy 6 cell lead/sulfuric acid agm. Time will be the true test. I bought it for an old Tripp-Lite 1000VA UPS unit and working great thus far, even with withlechoochi powers and its brown-outs. Mike B.

It works like a charm! My brother-in-law told me about this as his Monster RR battery went out. It was easy to install and so far has held a steady charge.
Joseph Andrew Young –
Would buy again
William J. Seelbach –
I bought 3 of these as replacement batteries for my toro e-cycler lawn mower. The old batteries died and I didn’t want to buy a new mower, so I opted to try to replace them on my own. These batteries were much smaller than the batteries I was replacing, so I had to use some adhesive to secure the batteries to the housing and put some foam pads between the batteries to keep them from touching or rubbing together. However, now the mower works just like new. These batteries were the best and cheapest option I could find. I only added 3 stars to longevity because they do technically have a shorter lifespan than the original batteries (but my yard is small enough that I don’t run out of charge before the job is done). The original batteries lasted about 8 years, but I don’t know how long these will live.
jec –
These batteries seem to be a good product and a good value. The seller’s customer service is excellent! When I discovered that the terminals on the batteries were larger than the connectors on my wiring harness, the seller sent me adapters at no charge. Definitely beyond my expectations!
Poroda –
Battery is an exact fit. Fast delivery.
Battery checker –
Make sure your check to see if you need an F1 or and F2 terminal, the terminal on this battery (F2) didn’t fit my alarm system wire, which require an F1 terminal. Wasn’t able to plug it in, but assume it would have worked.

Great price. Replaced kids electric jeep battery. Very powerful and long lasting before recharge required.

Fits and works in My Cyber Power CP825LCD. This was 10 bucks less than the Cyber Power RB1280A replacement battery. What was inside my CP825LCD was a B.B.Battery HRC1234W I guess Cyber Power uses these batteries and that battery lasted 4 years with many power outages, so I have to recommend that battery. I will update this post on the longevity and overall performance of the Might Max ML9-12 – 12 V 9 Ah Rechargeable SLA Battery.

Using this battery to store some energy from a solar panel. It provides light through an inverter and 12 volts to light up the gas pump outside. So far it is working well. Time will tell how good the longevity is.

Purchased this to replace the battery in my Cyberpower UPS. Most of these home UPSs use the same type of battery, and these are it. Swapped the battery, charged up in unit and it’s been working great since. Will definitely buy again when a UPS battery goes bad.
ProfessorStratios –
This is perfect for low draw or intermittent 12 volt applications. Works great with a sprayer I have but it now lives as a power source for an automated purge system for livestock water tanks. Great little terminal shape works well for spade connections. If the capacity works for you go for it.
Greg –
These are excellent batteries and my APC Unit works like new again. These batteries are just like the original APC batteries for much much less and work fine. No issues and will continue to purchase these batteries.

I have a portable speaker and the battery died . So i got this battery to replace it with. And now i am rock & rolling baby. I love it again. But i thing my neighbors don’t like, my loud music . Quite time 8 pm. Well this battery work great . be sure to look at youtube on how to replace the battery . it was easy. and cheep.
Deryck S Schnee –
Bought two of these for use in a UPS. Upon receipt charged to full capacity and then performed a test discharge to 10.75 V @ 18.00 A and again charged to full capacity. Results of this were consistent with my expectations from a new battery. Installed in my UPS unit and so far appear to be working fine. Will update review later should anything change. So far, rating 5 stars all-around.
Rachel –
My original battery lasted about 3 years but this one is already failing after maybe 9 months. Bought in July and failing before the following May. I do not know if it is old (shelved) or just poor quality.
Emily –
So far so good. We use this is a kids ride on tractor and get about an hour of combined riding time which is pretty good
Sarah Pathammavong –
This for perfect for my son’s Best Choice ride on Jeep with remote control. I Used it right out of the package to confirm that the Jeep had a battery issue. And the Jeep started right up like new! I also let it charge after that and my son gets longer ride times with this battery then the original that came with it! Great alternative then buying a whole new Jeep! It doesn’t come with the wires to hook up to THe Jeep so when you change our the battery be sure to keep all the wires! Will buy again if it ever fails
Alissa Story –
was able to replace my home FIOS verizon battery with this one twice, and it hooks up and works great. I recommend

Awesome cheap battery for my vexilar and portable fishfinder.
Aleksandra Beric –
I works as expect and for as long as expected.
TechnoFreezer –
Back in April 2020, I slapped it into my decades-old APC 500 and it jumped right back to life. Volts read 12.99 when I unboxed it. Two years later, a brief power blip caused the gear attached to the UPS to restart — a little clue that the battery was not holding enough charge to run the inverter. So I ordered this replacement yesterday, and it’s in the UPS already. We’ll see how long THIS battery lasts. I took off a star ’cause I expect at least 3 years out of UPS batteries that don’t get that much use. Our power is pretty reliable here, and has only failed maybe 3 times in the last two years. I’ll update when I have to replace it again.

I used it on my daughters power wheel. Great replacement battery.

Great little compact battery for my daughter’s dune racer. Wired in series, these things pack a punch and really move. She’s gotten quite a bit of run time out of them (45 minutes and they were down to 12.1v). Couldn’t be happier for the money!

Seems to work good in my Tripp Lite UPS. Smart1000lcd. Battery came with about 12.0 volts and fit perfectly inside my UPS just like the original battery. Update almost 2 years later: Somehow the Battery cracked open and ups faulted. I bought a new one. This one came with 12.97v. Works as expected.
maisonlumier –
Ok
James Haugen –
This goes into and ice auger. Space limits the battery size. This battery is as big as will fit. A stronger battery would be good and do a better job, but that is due to the limits of the design and no failure of the battery purchased.
Joe –
Works great. No problems

I bought this as a replacement for my Generac GP8000e battery. Other than needing to change out the ring terminals for push on terminals, it was a direct fit. Hopefully this one will last longer than the one that came with the generator.

I have had this in my granddaughters electric jeep toy for nearly two weeks now. It replaced the original battery that lasted about 3 years. This thing has not shown any issues in use and appears to have a higher start voltage (i didnt measure) than the original. We havent gone but about 3/4 mile trips so far and its still showing over 90% charge. If it wont make it a mile and a half I will repost and will also update when it fails.

This battery is great value for the money. I have purchased these batteries in the past and the only issue I have had is that they seam to last only two full years before you really notice that they will not hold a charge. Its still better then anything else at this price point.

This battery is better than I expected. My son can ride it for more than an hour without slowing down and that’s going up small inclines. The speed is a little faster than I like, but my son handles it well and has a great time! (no wrecks yet, knock on wood) Now the installation was not easy! I don’t think Razor ever intended for their batteries to be replaced. They just want you to go buy a new product. Anyway, back to the battery install. There are a lot of screws to do and some are very hard to get to. Make sure you get the one at the top or the case won’t open. I had to cut the wires off the batteries, strip the wire, and attach a female 16 to 14 AWG female disconnects. I will be buying Mighty Max products in the future!

I use a UPC (Uninterruptible Power Supply) to keep my computer and peripherals running for awhile in the event of a power outage. My old APC power supply had stopped working (eventually the rechargeable batteries in these things will die). This battery was a perfect replacement and was super easy to swap in. Replacing the battery saved a ton of money as well as letting me continue to use the original equipment rather than toss it in the landfill.

Batteries arrived with good condition and fully charged. On a backup test it powered my laptop (7 years old with lower operation effeciency than today’s laptops) for almost two hours before hearing the low power warning beps. There are some issues with my old Belkin VA1500 UPS system (which holding the batteries), which occasionally shut itself down and light on the red system failure light. I am still working to have this issue resolved. Believe it is nothing related to the battery pack
Mlwesto –
Installed on a older UPS. Worked well.
Ray P. Lucero –
Dont know how long it will last. Popped it into my monster roller radio and it fixed it. Would not turn on. Looks to be charging up ok. Happy with this purchase so far.

This one didn’t fit my UPS, that I bought it got it form BUT bought same brand for my moms garage door opener. Been in the opener for about 5 years now and provides juice to open and close door during power outages and charges fine.

Rather than spend twice as much for replacement batteries from the manufacturer of our Cyberpower UPS, we tried Mighty Max batteries. They arrived fully charged, fit perfectly and provided extra capacity compared to the original batteries. Now the test will be how long they last. We have now replaced batteries in 2 UPS with Mighty Max batteries (original batteries lasted nearly 5 years).

Seems ok

There was enough detail in the specifications for me to have confidence that this battery would work in my UPS. There are many batteries that are essentially equivalent, but which have minor differences in the connections or in the dimensions as to make them incompatible. This one fit perfectly, and it works. One and done. Job taken care of. Finis.
B. Trahan –
Good Battery and works as it should. Had to redo the connectors on it as not plug in play to Razor it went in but was easy enough to modify the connections.
Jose Sanchez –
Good battery no bad review
jose –
Thanks
Greg Dyer –
The battery replacement was very easy and the replacement was almost OEM. Simple to connect and put back in service.
Todd C Lehr –
Perfect fit for my need!
bummster –
I have an older APC ES-550 UPS with a dead battery. Swapped this battery in, and all is well. And at the time of my purchase, it was $15 cheaper than the APC branded battery.
Daniel –
Had to replace my battery on my monster roller 3. This was easy to replace and works great
Amanda –

Arrived quickly and worked. What else could you want
Bruce Ollerther –
Good replacement so far

I installed this into my Tripplite UPS and saved from having to buy a new one (UPS). Easy install, good price, what’s not to like?
iamcarel –
its still workin’….I’m happy
Robert –
Thanks so much. Great choice.
Kid –
Good battery!
Iceman –
Can’t rate longevity…only in service 3 months.
robert clouser –
Looked for this battery locally and found one only $80.00 So far so good battery is working out great in my daughters 12v jeep
1stHand –
Major bargain on a replacement battery, compared to the $85 that the equipment supplier wanted for an equally rated replacement. This battery was a bit shorter, so rather than alter the hold down clamp, I cut a base plate for the new battery to set in from a piece of scrap Trex decking to make up the difference. Works great!
COAST1E –
I purchased this SLA battery as a replacement for my CyberPower CP850AVRLCD UPS’ old and bad battery. It’s a perfect fit and works great. The manufacturer’s website states that an 8 Ah battery is required, but I opted for a larger-capacity 9 Ah battery instead. No issues; good to go!
Anna H. –
Not the battery for my generator, posts not compatible. Could not return the battery and exchange for the one I need.
J –
Ups was completely dead. Replaced the battery for this one. And now works like a brand new one. Very inexpensive fixed.
Charles Foster –
This is a good replacement.
Rob B. –
I may have needed to wait a little longer for shipping, but it was totally worth it. The additional Amp Hours made a nice improvement to my APC 700… I mean, if your battery in your UPS is dying and doesn’t have any other problems, may as well replace the battery with a higher capacity one as long as it fits the type (Due to the way they charge) and suits your dimensional requirements.

Great quality t

This seems to work well so far as an easy replacement for a Cyberpower CP1000AVRLCD 1000VA UPS. The previous battery (BB Battery HR9-12 8Ah/12V) had failed after a few years in the UPS. I believe the equivalent cyberpower OEM battery is now RB1290 (9Ah/12V), but interestingly that is not the battery that was inside my older UPS. This Mighty Max battery is exactly the same size, has the same terminals, and actually has 1 extra Ah of power in the same package. It arrived with about 60% charge but charged up again in a few hours and is now reporting about 10% more runtime than the previous battery ever did.
MJTexas –
Exact replacement!!!

I installed this battery into my kayak for the fish finder (Garmin Striker 4CV). My fish finder will run for an entire day and night, plus more. I always charge it when I get home from a trip, so I do not know exactly how long it will operate the fish finder. Since it runs for so long, I plan to install LED lighting in my yak and run them to this battery. I have it installed sideways in a waterproof box and it works great!
Adriana Rodriguez-Martinez –
My dad’s speaker Monster RR3 stopped working because the battery burned out. I was able to find this replacement easily and it arrived fast, even though it did not travel via airplane. So easy to install and right now working better than the previous one.
michael –
Nice upgrade from the 7ah . Same dimensions
Carl A Richard, jr. –
Great product!
Andrew Hafner –
This battery was a replacement for my internet service back up system. All specs matched and the item fit.
brenda –
Great long life battery for rigging up flounder gigging light.
Riverside –
Ok
T. Hill –
I use to power a cooler stereo and this thing runs all day with no fade, then charges back up fast. Would probably work for several days straight, as this stereo isn’t too energy thirsty, even when playing loud. Very happy with this little battery! Better than carrying a big car battery around!
Robert –
It was a good investment….It got myMonster Boom Box running like new!
Malik ahmed –
Good
Chuck Booksh –
As described. Replacement for powered speaker.
Randy L. –
I’ve been using it for 2 months, it works as I expected it to.
Daimeian Underwood –
Worked perfectly as a replacement in my Ion Block Rocker.
Robert Gilbert –
So far the battery seems to be functioning as indicated. We are using it in a Monster speaker box which charges it when plugged in.
Michelle –
I used this to replace a speaker battery, lasts way longer than the old battery. I don’t have to charge for almost a week.
Lisa Thor –
This was a direct replacement for our old (2015) Block Rocker. 10 minute job to swap in the new battery.
Web Customer –
Waited a while. Still working fine. Batteries seam great after a lot of use.
Tmrobots –
Have about 6 cylces in it so far. Seems to last about long time. Have not yet run a continuous use test. Will update with those numbers from my Bluetooth block rocker speaker
Aaron Key –
Works great in my ion block rocker! Like new!
Oscar the Grouch –
This is my second Mighty Max Battery. I use these to replace old, failing Powerwheels batteries. These things are sized well. To those of you using these for Powerwheels, get a higher amperage (Ah) value. The higher amperage means longer run times. So if you get the 12 volt battery in 9Ah and 12Ah, the 12Ah will run longer and keep your kids happier longer. Happy with Mighty Max. No complaints.
Viark –
Got this to work on wifes outdoor fan and it seems to last for days on single charge.
bobby –
Bought this for my son’s ride on Jeep I upgrade from the stock 12 volt 7 a h to this 12 volt 9 a h performing well so far it even made the little Jeep faster
rogerwash –
This is the second battery I have purchased and they last at least 2-3 years, great product
Patricia Kalan –
Just got so longevity is yet to be determined. Larger capacity than original battery so that’s a plus, potential longer run time. Since it’s the same size and terminal configuration, installation was easy. This was for a small APC UPS.
Fast Finish –
We use this battery to power a mobile sprayer for work. So far so good. Will update if it fails prematurely
H Davis –
Couldn’t give a good rating just received today
Laura Schwarz –
New battery has worked great for us. We were given the motorized toy tractor but told it needed a new battery. This one charges quickly and lasts a long time!
referencelibrarian55 –
Keeps a 15+ year old UPS running for a fraction of the replacement cost. Actually better and slightly more capacity than original battery. Past ones lasted about 5-6 years, this is my 3rd replacement. Original lasted maybe 5 years, maybe a little less.
David –
Perfect
Laser1981 –
Great value
K. Kidd –
This battery does NOT fit Block Rocker

No issues. Works like a dream.
Dominik –
Very good batteries, I highly recommend they last a long time compared to the originals.
Kindle Customer –
Used this to replace a battery in a kids jeep. The voltage and a/hr were dead on. Runs 30 minutes on a charge
Glenville Foster –
Battery arrived fully charged and ready to use. Plugged it into my UPS and it is working fine. Very satisfied so far. Ordered another for my portable air compressor.
Web Customer –
Have it hooked up to my Garmin fish finder. No problems.
Honda703 –
Replaced my UPS battery today. It was barely charged and started out with one bar on my charge display. I’m sure this is not a good sign of longevity. Will update review as needed.
JC Hoit –
A used dead $150 UPS revived with a $20 battery. Not only do I save by simply replacing the battery, having a UPS is essential to my computer’s and TV’s health. Power dips are frequent where I live. The battery is holding up fine.
john hayes –
Used this to power about 15 ft of LED lights for my Santa sleigh. If I am showing the bike lit up for 6 to 8 hours, this works well and no drain on my motorcycle battery.
Michael Young –
Haven’t had it long enough to evaluate longevity. Works well.
Tom E. Foster –
Great,so far
a1h2o –
Unsure how well it will last, but batteries worked for me in apc ups. Was easy enough to setup and install.
Mike Hegstad –
I bought this battery as a replacement in my Silent Partner tennis ball machine. It’s working great and now powers the ball machine longer than I can last (about 2 hours). Still too early to rate longevity. The battery replaced lasted about 18 months before storage capacity dropped in half. Hope this one lives longer.
Dave Lauber –
I do like these mighty max batteries….they always fit right with the right connectors and they evn last longer than the original factory battery at a great price.
K. Kalb –
Very fresh with good charge on it. Read almost 13v right out of the box.
Choncho Gorilla –
Fits my vexilar great
Queens_NY Reviewer –
I bought this as a replacement battery for my kids Power wheels. The charge lasts about 8-10 minutes, it is really fast during those 8-10 minutes but it is more of tease for my kids. If you are buying to replace a power wheels battery then look elsewhere.
Peter –
Product works as expected and I have no complaints yet. I bought this to replace old batteries in a UPS, so far it works great and it didn’t break the bank.
NickA –
Brought an APC battery back up back to life! Much cheaper than an OEM replacement and it has been working well ever since installation. Highly recommend it!
luis briones –
Very satisfied with this lasting battery
TURK –
Upon receiving my battery I ordered, I discovered the terminal smashed in, nearly broke off. when I try connect it, then it broke off. Luckily, their customer support service was great. They replaced the battery with no charge. Thank you.
Michael –
Great
Cory K. –
I’ve had this product for a few months now, zero issues. I’ll change my review if the product fails
Old Grouch –
Bought this to rejuvenate a dead ups that I bought at a yard sale for cheap. Popped it in, and the ups came right back to life and is working perfectly. I would bet that probably 90% of the dead ups units that people trash only need a new battery. That’s been my experience I’ve now brought 3 of mine back from dead this way.
JoeyBagoDonuts –
Doesn’t seem to run as long as the Duracell it replaced, before it needs a charge. Time will tell about longevity!
Scatman –
Larger capacity for the same size, fit perfect, my terminals fit right on and tight. If it lasts half as long, as the original battery, (8yrs) I will be pleased.
LM –
Bought this for my son’s toy riding car, it lasts 10 times longer than the silly batteries they included with it. Need to buy another one or tow for my low power ham radios.
Gregory Houseknecht –
Fast delivery and the batteries are working great!
C. Gene Hamilton –
Batteries seem to be working properly. Will update the review later if things change.
Destiny McIntire –
Best sla battery I’ve found
Alejandro Valdes –
Great backup battery for my sons electric motorcycle!!!
KELLY –
The battery arrived with a nearly full charge. The spade terminals survived the battery being packed in a much oversize box with no , none , zero packing material, and the battery slamed around tearing holes in the box from the projecting spade terminals on the battery. These terminals had protective insulators for shipping. I like the fact that the battery is 9AH in the case of a typical 7AH. Dimensions were the same as an original 7 AH. The spade terminals on the plus and minus of this new 9AH battery were the same size and my old battery had two different size terminals so a crimp on of a new space connector was needed on my equipment. Thus far it seems to be a good quality battery electrically and mechanically.
ana –
Worked fine with power wheel
Peanut brained Bill –
Two months on an electric quad and still performing top notch.
Sharkman –
Great for the money. Not too bulky and holds a charge.
Jennifer –
Fit exactly in the place of the old one.
DMVA –
So far, so good. Smaller than the old battery, and shipped with a 13V charge on it. Hopefully it will last longer than the non-AGM previous batteries we’ve had, which made maybe 2-3 years (with periodic fluid-level checks on them, along with voltage checks etc as I’ve become a little too-obsessed-maybe with making them last). Should it crap-out early, I’ll update the review. Used in an electric lawnmower.
Rob G –
Worked right out of the box
Uncle Milty –
Purchased a replacement For my APC On interrupted will power supply . The batteries work so well I ordered another pair for a larger APC UPS that I had. Everything fit perfectly and the value I received was great!

This has been a great replacement for my daughters power wheel.
Win Huang –

I put this battery in my sons razor pocket rocket and it works great! It will run for hours it’s seems on one charge and it was super easy to install
