The battery fit perfectly and worked. The packaging was very well done allowing the battery to arrive without any damage.

I’ve had this battery for 3 weeks now. It arrived 1/2 discharged so I charged it using a ctek charger – took several hours. After charging the battery read 13.4 volts. After 3 days it dropped to 13.1 volts and held for 2 weeks. Then it dropped to 13 volts – we’ll see how long it retains its voltage
Christine/Scott C. –
Too early to know longevity but fits and performs great upon installation.

Fast Shipping, arrived charged, exact size as the old 19AH battery CB 19-12 (12V 19AH). Installed it in my Stanley FATMAX PPRH7DS professional power station jump starter: 1400 peak/700 instant amps. One thing I did notice is the old battery has thicker terminals, you can see them in the attached photo. Holds a charge well.

This is driving my telescope and it’s the perfect size and power supply for the money. Many telescope suppliers have a bunch of extra stuff and they cost a fortune when all I need is a battery and a cable and this is it. Thank you!
Edward Novak –
The unit arrived with a full charge despite the USPS taking multiple weeks to deliver it from New Jersey to Pennsylvania. It was well protected by the packaging and the unit appears well constructed. It’s far too early for me to comment on its longevity since it only arrived a few weeks ago.

Battery is as described. Replacement for JNC660 battery jumper. This is the 2nd battery I’ve purchased for my jumper over the last 6? years. I am hard on battery as unit stays in van with temperatures ranging from 0F to 130F. Also important to recharge on a regular basis (how often depends on usage and storage location) to keep battery healthy. I often don’t. Shame on me.
Max Byrd –
VEHICLE JUMP STARTS. My jump box came with a 18 AH battery. This 22 AH was size and fit right in my box.

Seem to work well OEM
T.G.Vaughn –
Perfect replacement for portable jump starter.
DGB –
I had to return it, as it turned out to be the wrong size – NO fault of Mighty Mite – problem with OEM’s spec sheet, and their battery not matching their own specs! Mighty Mite is a good outfit. Battery was well packed, delivered on time, but returned without use.

Exact product that was needed
Thomas J. Hood –
I needed a new battery for my jump pack. Fit well. Came charged. Took remainder of charge without issue. Worked as it should.
C. Ivich –
Just installed with no issues whatsoever. Charged up to max overnight. Appears to be a perfect replacement of the factory original BB Battery HR22-12 battery with one caveat: The BB battery weighs 14.3 pounds. The Mighty Max ML22-12 battery weighs 11.9 pounds. That’s a significant difference for two batteries with the same specs. I have not yet needed to use the jump box though I believe it will perform just fine but I’m curious as to the new battery’s longevity. The original performed on a sporadic as-needed basis for over ten years. So four stars strictly because of the weight difference.
Dack –
Battery was a perfect fit for my Sears Diehard 1150 jumper. Came fully charged and ready to go.

Not even close to being as strong as the original battery in my jump box. They’re not lying: it is a replacement battery, that’s it.

I don’t know yet. I just got it around 10 days.

Bought this battery at roughly half the cost of the official powerwheels jeep battery. Capacity is roughly double. Only had to cut off the proprietary connector and add some eyelets to the wires to bolt onto the battery. Fits within the compartment after removing old battery restraint.

Not exactly the battery I ordered and not a lead acid battery like the description said but a I got a gel battery instead and the color is blue not black and with different hookup to connect my battery jump Pak. I made it work but not sure what to think except I will have to see how it works. Not a big fan of gel battery’s.
Customer –
So my battery jump starter didnt work when i connected to the battery to start the car. So i found out it was the battery from the jump starter and I changed it. Now it works and this product was helpful.
Al Sim from Silicon Valley –
Good price. But, cable connector differs from the OEM version, which is a problem.
Steven A. Noschang –
Installed this on my DR lawn leaf Vac Took about 10 minutes to install and fits perfect turn the key and it starts right upBut I do keep a battery tender hook to it since it’s something I don’t use too often
Verlyn R –
I’m using this to power a 400W inverter pack. It seems very powerful. It will easily run my Dremel tool or power my 22 inch flatscreen tv in my Jayco camping trailer. I’m very pleased with my purchase. I like that it is sealed and can sit/lay in any position without worry of spilling.
regular shopper –
This battery is a perfect replacement for my JNC660 jump pack whose 6 year old original battery failed. Couldn’t see throwing the hole unit in the trash why not spend $45 instead of $150 when everything else works fine.

This replacement battery worked perfectly with my DSR PSJ-2212. The size was an exact replacement but the wire terminal mounts were different, The OEM battery had flush mount nuts and the wire terminals were bolted in. The Might Max battery has universal posts with a through-bolt style of mounting. This is not an issue but I wanted to mention it in case a future customer is corcerned about fitment issues. Before and after photos are attached.

Outstanding item, super quick delivery, highly recommend.
Pomaikai –
I couldn’t justify paying the replacement battery for my JNC770, but the ML22-12 looked like it might fit, at a very decent price. It arrived quickly, and I took care to study the original battery connections before I took out the original – and quite weak – battery. I should have taken pictures, but trust me, it is just different enough to bend the copper strap to fit to the battery post and reorient the wiring to fit inside the case without pinching, and with very tight bolts and nuts. I put the battery on to charge, but it was showing 13.0 volts right away, and didn’t need further charging. I used it the next day to jump my wife’s Mercedes CLS63AMG that wouldn’t start with the original JNC battery. The Mighty Max brought that car to life, allowing her to drive the car to the dealer for servicing (and she decided to trade it in for a less-exotic Mercedes). Thanks to Mighty Max!

Mad Wabbit –
Perfect fit and replacement for Jump N Carry 660. OEM battery is shown in 1st picture (BB Battery HR22-12, 12 volt, 22 amp hour) that lasted for 12 years before it would not hold a charge. Hopefully this one will last as long…. Certainly a reasonably priced replacement since Jump N Carry wants approx $149 for a replacement battery purchased thru them. This is more than a new, complete unit sold online, making the entire jump n carry a disposable item from the manufacturers perspective. By the way, their replacement is 18amp hour and not the original 22.The battery that I received matches the second picture on the website – with a Mighty Max label and no product information. This means no model number, voltage, amp, etc; not listed on either front or back. It would be prudent for anyone replacing the OEM battery with this one to write this type of information on it (or save a picture in a file for future use) so they can purchase the correct one and not damage the unit.

Came fully charged and does the job.
Paul Jones –
Really fast shipping. Work perfect in HF power pack.Replaced a 17ah with this 22ah. Will buy again.
Michal W. O’Hara –

kenny –
I bought the ML22-12 battery from Mighty Max themselves. I received the battery in 3 days even though it said 7 to 14 days. The battery was boxed in Styrofoam. It was fully charged with 12.9V. I connected a battery charger/maintainer and it showed no problem with the battery and the voltage is now at 13.12 without the charger/maintainer connected. Its still at 13.12V after several days so it’s holding a charge well. No discharge for several days. I bought it to replace the battery in my jump starter box. I bought a 22ah instead of a18ah battery that was originally in the box. I wanted a stronger and longer lasting battery in my box. They are the same size so it fits any jump box using these type of batteries. Also, the manufacture date was 2018, Oct 21. ( HJ21 printed on the battery ). Also, the name and all information about the battery is printed onto the battery. It is not printed on a plastic or paper label and then stuck onto the battery. If you receive a battery with a stuck on label then it is a not a Mighty Mac battery. Contact the sender immediately and get a refund or a new real Mighty Mac battery.

My review is still not complete. I can say that when the batteries arrived, there were no labels on them indicating what the number of the battery it was nor anyway to identify them. Makes me a little nervous whether I received the correct batteries.The batteries were perfect in size. They do seem to be lasting allot longer than the old batteries. They also have better power for going up hills.

JEFF MCCREA –
Well, it’s been about two years since I bought this battery for my electric start generator and it’s worked flawlessly. The original was a cheap Chinese made 18 amp hour unit and it lasted 6 years with the factory charger that the directions say is supposed to stay plugged in all the time as it float charges and shuts off automatically. During those 6 years, I noticed that the generator would crank slower and slower every few times we used it, (Power outage backup use), until it finally quit altogether. I called Loews where I bought the generator and they wanted $98.00 and 2 weeks to get an original replacement. This Mighty Max unit cost me $44.00 with non-prime free shipping and it’s 4 amp hours larger than the original in the same size package. I take care of my equipment so this generator will last me a long time. My last generator lasted me 22 years and still works but I needed an electric start unit due to back problems. I can’t pull the rope anymore. The next time I need a battery, I’m going to go with Mighty Max again.

Works fine in my Stanley portable compressor/jump start unit. Easy install and better than older OEM battery.
Avid Shopper –
Fit well as replacement battery for ATD-5926 Jump Start (now discontinued per manufacturers website). Arrived in good condition though packaging came apart in transit and most of the hardware (washers/nuts) had fallen out (used previous hardware which I’d saved). Voltmeter on jump starter indicated battery was 100% charged on arrival. Too early to comment on durability, etc. Felt very satisfied I was able to replace battery as opposed to having to shell-out another $100+ for a new charger (liked features on one I had & was used to using it).

I bought a jump pack 15 years ago and just recently the battery no longer took a charge. I replaced the battery with a ML22-12 which has more amps. The price was a fraction of what I paid for the jump pack. Hopefully it will last another 15 years.

Received battery yesterday. Charged overnight in my old Clore J900. Tested by removing auto battery cables and connecting them directly to jumper box cables. Started car 6 times with about 30 seconds between jumps. Could have done more. Hooked back up to charger and was fully charged within a few minutes. Great so far. Hope it lasts a few years
prmaddox –
Great quality product.

Older Diehard 1150 had stopped charging. Research showed this battery as a suitable replacement. Older model required substantial disassembly, but no problems. Battery charged to 100% within 72 hrs, has been discharged to 50%, and recharged quickly.

Fits inside my booster like the original did, works well so far, took it to the lake to boost my boat motor, forgot it in boat for about 3 weeks, checked voltage and it was 13.3 after boosting and sitting. Three stars only because they tried to deceive by putting Schumacher in the description, this has absolutely nothing to do with the company.
Mr. Teddy B –
works, as it should just recharge every 3 or 4 weeks or more often if you use it a lot, keeping it charged, is the key to long life.

I got this battery for 12 volt requirements to power my telescope drives. But I also used it to breadboard 12V auto hookups.

Mark Day –
I ordered two of these, and as I was assembling my project I partially toar the label, so I decided to just tear the rest of the label off. Look what I found, UB 12220 batteries, their not bad batteries but I could if bought them for about five dollars cheaper if that’s what I wanted. I don’t know why companies do this, I realize there’s only so many battery manufacturers but why do so many companies buy someone else’s product, probably at wholesale, slap their name in it, and bump the price up? I find those types of business practices sad, what sucjsus, I’ve spent over five hundred dollars on mighty max batteries the last 6 months, I bet none of them are mighty max. stepped up to rectify the problem, I’m very satisfied how they handled it, you can read my response in the comments.
CLB –
This battery seems to be a good solid replacement for my JNC-660 jump-n-carry. The new battery charged correctly and read: 12.85 volts DC out of the box. The old battery I removed was a B.B. Battery, HRC22-12S. The old battery would no longer hold a charge (read bad @ 10.5 volts). The correct replacement battery for the JNC-660 is a 22AH (amp hour) battery and not an 18AH (like I keep seeing on ). The new battery comes with bolts, flat washers, lock washers and nuts. Hopefully – I can get 3-4 years of service out of this new battery.
R. Yost –

J. Kelley –
Needed a new battery for my Schumacher PSJ-2212 DSR which the title of this product states is the replacement. The connection terminals are totally different. The original battery has a threaded hole with a bolt holding 3-4 wires on each side. This one as pictured had blade style connectors with a hole drilled through. I had to find a nut that fit my bolt, and slightly enlarge the holes in the battery to get it to work. I also charged this battery before installing, and it took quite awhile and a couple different chargers to get it to show 100%, haven’t tried to let the Schumacher PSJ-2212 DSR charge it yet, nor have I needed to jump start anything, hope it works when needed.

V. Nguyen –
Holds good charge so far. tight fit for my tennis ball machine lobster elite 2. I made it work with some adjustments to the remote control receiver cable to give it more space.Edit 3/20/2018:After not using the ball machine for approximately six months, but leaving it hooked up to a battery charger/maintainer the entire time, I finally took it out to the courts. It is no longer holding charge for more than five minutes. After about 50 balls, it stops and the red low-battery light blinks. I turn it off then on again, but the red light begins flashing again. I contacted the company which suggested that I leave it charging for two days straight and it might be revived. So far, no luck. It still dies after about 5 minutes of using the ball machine, though the battery charger shows 100% fully charged.Another edit: I just realized that I bought the wrong battery, as it is a DSR type that I think is meant mainly for starter boost applications. This is what I will order as a replacement: ML22-12 – 12V 22AH UPS Battery Replaces 20Ah Leoch LP12-20, LP 12-20 – Mighty Max Battery. Someone commented for the ML18 18AH version that it works great on their ball machine, so I will order the 22AH version for longer use.Edit 3/25/18In trying to get this battery to hold a longer charge, I realized that its short charge may be due to my error. I have a charger that can be switched between standard and AGM. I’ve been selecting STD, but I now have it on AGM and it seems to be doing the job, as it’s showing only 63% and very slowly going up, instead of rapidly approaching full charge under the STD setting. Will report back if this does the trick.

The Sears Diehard battery jumper tells you there are no user serviceable parts inside So, when the battery dies in the device that is supposed to help you jump start batteries, inflate tires, provide USB outlets power small 110v device — you’re just supposed to throw it away??? NO. You buy a new battery for the battery jumper!After a month, my jump starter is still back at full original capacity. The only reason I gave 4 stars instead of 5 is that I can’t tall you how long it will last. If it lasts 5 years, and lets me edit the review, I will go back and change it to 5 stars!

Perfect fit/replacement for the original battery in a Diehard Platinum portable power 1150. Not a big effort to open the Diehard unit and swap batteries. Fully charged it and checked a few weeks later and still at 100%. I’ve added a reminder to my calendar to charge the unit every month to keep the battery from going bad. The gel batteries need this kind of maintenance. I’ll report back in a few months on how things are going.
Jim –
I bought this battery to replace the expired battery in my Husky HSK 037 portable battery jumper from a box store. It is 10 years old and outlived it’s service life which preformed well. The battery I chose was the Schumacher SLA 12 volt 22 AH from Mighty Max Battery. While the unit is not produced any more it had all the features I wanted like a 400 watt inverter, air pump, light and pressure gauge etc I could not part with it or replace it for the cost of the battery alone. The battery came in well packaged, clean, with hardware and is totally acceptable as a direct replacement. As one who is very particular about his tools and has high standards for equipment that needs to be depended on at a moments notice. Beside the time it took to disassemble and swap out power packs the unit fit very well, no modification needed and is now back to its original working order for many more years. I would definitely recommend this battery and Mighty Max Battery as a supplier. I will not hesitate to use them again in the future and I am 100% satisfied with the price, delivery and service by this supplier.

***UPDATE AT BOTTOM***I’ve purchased 4 of these batteries already and they have served me well. I use them to power an electric motor for a go kart and they have pretty good battery life even under heavy load.As for how well they hold charge; I’ve not seen any decrease in the voltage the battery holds in the months that I have been using them. Not only that, but they were used and stored in less than ideal conditions. If you keep these batteries in a climate controlled environment, where they aren’t being tossed around, then I’m sure you will get a very good lifespan out of them.All in all, good battery for the price.***UPDATE***I’ve been reading that some of the batteries that people are receiving are not the original ones pictures, so my review is for the OLD ones that are pictured, AKA model ML22-12I’ve had these batteries for over a year now and they are still going strong! They’ve been shorted, drained nearly all the way, overcharged, and have survived some of the colder temps up here in Minnesota. I do store them inside during winter and do take regular care of them like any batteries, but they’ve held up well.Still charge up to 14 volts like they were new!

This is the second battery of this type I have bought to replace a worn out jump start battery. It is actually an upgrade in amp hour capacity over the original battery that was removed. To bring an old jump start battery to new life, open the case, disconnect the terminals, and measure the old battery dimensions. Shop for a battery that fits those dimensions, but gives you the most amp hours.

Quick ship, arrive fully charged.

Worked like a charm

Bought this as an upgraded battery for my daughters power wheels. Had to buy a separate in line fuse and make my own connectors but the payoff is worth it. The thing lasts for freaking ever on her Barbie Jeep power wheels.
Robert Rivera –
The battery performed well and is a good vallue.
Stewbert –
An AGM for less than many flooded types. 5 stars for now. I will return with longevity report.

great item
WAG –
I have had this battery for about a year now. I use it to run my LED lights on my John boat, with LED light do pull a lot less amps per hour then standard incandescent fixtures but I have only charged the battery one time! Great product, great price!
Michael F. Lamb –
Excellent product, delivered promptly. However, I purchased two units and the packaging was barely sufficient. A corner of the box was crumpled and one battery was dented. This , luckily was cosmetic on the battery casing and did not inhibit performance. Batteries were used for a Go-Go Elite mobility scooter and are working very well.I would use this source again, despite needing some packaging improvement.
Airwaffle –
Arrived earlier than expected which was good. I used this battery as a replacement for the one in my Sear’s Jumpstarter that was more than 4 years old and was no longer holding a charge. It is a pain to get the old one out and the new one in… just be careful… wear some rubber insulating gloves to avoid accidental shock.Initially had a charge of ~76%. Plugged it in for a couple nights, and now sits at 100%, and works properly (compressor, jumpstarter, etc..).As generic as this battery looks I don’t expect it to last more than 2-3 years as long as I charge it two or three times a month. Less than 2 years if I take poor care of it.
opinionator –
Battery arrived on time as promised and appears to perform very well electrically so far. It was installed as an exact fit replacement for the original battery in our Wagan 400 watt Power Dome EX Portable Power Supply. It offers somewhat more storage capacity at 22 ampere hours than the original did at just 18 ampere hours. The packaging left some cause for concern because one edge of the carton had been ripped open during transit. But good packaging within the carton limited the damage to some surface abrasion on the battery that doesn’t appear to have affected integrity or function.
Phil –
Exact replacement battery. No fuss, no muss. Pooped right in. Could not be happier.
Waltair –
Perfect, it did everything it was supposed to do, it was delivered in good time and installed as a replacement battery in a jump starter it increased the AH capacity and 12 volt low draw output.I’ll do it again in a minute if my other unit fails it’s battery.good deal all around
Jay the Magnificent –

Works perfectly in my DieHard power pack system! The power went out in my house two weeks after I installed this battery and I was able to watch tv for 1hour and run a small fan, and charge phones for 5hours.
jaime manes –
Battery fit great and works great.
J. D. Gold –
Arrived quickly, fit compartment inside of emergency charger, had the correct type of connectors as the old battery, took initial charge well and I presume will hold the charge and perform well. I won’t know that for a few months.

Please with item.

I purchased the replacement battery ML22-12 for my battery jumper starter unit by Statpower. The replacement battey is a perfect fit just like the original. I also have an AC outlets power inverter 12v to 110v that is mounted to my jump starter unit and it’s working fine now. All I need now is to replace my AC adapter charger which over heated due to the old defective battery.
JE –
exactly as described
Kenny –
Worked great, everything was as expected and replaced the original fine.
IMVeryJudgeMental –
Got this for my JNC660 because another reviewer said they got it for the same model. It’s an exact replacement. I figured I’d charge it with my Schumacher charger first but this battery came 100% fully charged. So I just connected it, closed my JNC660 up, and I’m ready to rock-n-roll. The original battery in my JNC only lasted 4 years 🙁 but this battery made it economical to bring mine back to life and is as good as new!
Daniel Lee Dellinger –
Works better than original battery exact fit
David S. –
Several replacement batteries for the type of charging unit that this battery fits are offer only 18 Amp hours. The 22 amp Hour battery has a little more power and endurance and that is a plus.
Charlie –
Great replacement battery for my old jump starter. Battery appears to be good quality and holds charge well. Very satisfied with this product.

Marvin G. –
I received the battery in the time frame promised and the packaging without any problems. I installed the battery in my sears all in one jump starter, it fit perfectly and had about a 70% charge. I check it periodically and it holding it charge. I would recommend purchasing batteries from Mighty Max Battery.
James K. Vandervort –
its a battery, we will see how long it last.
rick demchuk –
ok
Donald G. Trosky –
great price quick shipping item better than original,,,a credit to Thanks
Gregory S. –
Not quite as heavy as the battery that came in my JNC jumper box. That means that there’s less lead and it probably won’t last quite as long. But at less than half the price of the factory battery, I still think this is a better deal since I can replace it twice for less money. It holds a charge and works great.
Michael armistead –
Great product and fast shipping.
Dutch S. –
easy
George Clementi Jr –
Works and fits perfect.
JD –
Good price, and so far the batteries work great in our little electric scooter!

I used this to replace a battery in a Diehard battery pack. If it lasts it is a great buy. Much cheaper than a new battery pack.
Robert Dinsmore –
Outstanding quality and a perfect replacement for the old Die Hard in my Craftsman portable jump starter.
7cjbill2 –
Used it to replace a bad battery in my Schumacher jump starter. First of all, it is the correct size/rating for the unit, however, the terminals are not the same. I had to modify both the eyes on the jump leads to connect to this battery, as they were jut too large to bolt right on (shaved them down a bit). The battery that came out of the unit had the threads in the battery itself, whereas this battery just has terminal eyes. At least the battery came with bolts/nuts. Seems to be working well, came out of the box fully charged. Deducted one star for having to fiddle with the leads to get them to work…easily done with a Dremel, but still took longer than it should have.
Consumer –
Great product and awesome customer service. Couldnt ask for any better.
Matt Marek –
Good battery, actually holding a better charge for the Schumacher PSJ-2212 than the original battery it came with though my only complaint was the connector post were not the same so I had to modify it to fit.
Chris Neal –
Bought this as a replacement battery for my DSR jump box. good price and was able to swap right it. Works as it should.

Keith J Papania –
A spot on match to the battery inside my Sears Diehard Portable Power 1150. When the battery inside goes bad, DO NOT throw out or recycle the whole pack! Replace the battery inside with this product. A Phillips screwdriver and a small wrench set is all it takes! My powerpack is like new again!
Mark Schukei –
seems like jump pack is a little bit weaker now then when it was new but it does work
Horace –
I use this battery for a homemade jump starter I built. The battery packs the power I need and fits perfectly in the small igloo case. It was shipped quickly to Florida and came with terminal screws also. I will buy from this seller again.
Squirrel –
Used for a generator works awesome. Good cranking power!

Works great. Perfect replacement
Happy Camper –
I used the ML22-12 battery to replace the worn out battery in my Black & Decker Jumper Box. It was a perfect fit for the 19Ah battery that came in the jumper box. It was easy to replace the battery and much cheaper than buying a whole new jumper box.
Allan –
Quick shipping,perfect fit, good price.
Bill M. –
Very satisfied
MONOLITH –
cold weather arrived a little late. well worth the wait. fully charged delivered the punch i need for my transfer diesel pump. daily use i will check back if problems arise.
Bill S –
The battery arrived and was exactly as described. It had about a 3/4 charge and came up to 100% in about 2 hours. I installed it on my natural gas generator and it started up without any sign of the starter motor slowing down.This battery is intended for high starting current demands and it performed perfectly.I recommend this battery and Mighty Max.
Al D –
Fit my jump start perfectly and arrived fully charged

Nelson Kallis –
Good battery so far. Only used it once since charging it. I use it tailgating as a power source.Better price at than local stores.
David Williams –
Used for portable ham radio ops. Does a fine job. A bit heavy, they all are though!
Miguel Etheridge –
Bought this to replace the one that went south on my Sears portable car station after it quit working. Thought about throwing the unit away and replacing it but took a chance and purchased this replacement battery. This battery had been recently manufactured which is an important factor when purchasing one and after replacing the original my Portable car station unit works better than new. It has been a month since I charged the unit and the battery is still at 100%. Saved me $70.00, the local Battery Plus store wanted $90.00 for the same capacity battery and I paid less than half for this one.Would definitely purchase it again. Highly recommend it. Hope this helps
JZ –
no problems
Sgarzi’s Machine works –
Outstanding!! Great price, perfect fit!!
nm835 –
I know more in a year or two – but works- It would be very cool to have some kind of battery state indicator like they do on the bigger models. But this product offered good AH/$$
Roland –
These batteries are the right size and weight to be easily portable for our use to power either HAM radios or astronomy gear. 22 Ah packed into these is ideal for our use….we use two that are nested in a $10 little cooler so they are easy to hook up, switch, or charge when needed. Long term use has not been tested yet. So far, after 10 or so uses for several hours each, they have done well.
Sam –
This is my third one. They hold their charge well and I have had no problems. Used with a small solar panel.
Frank Von Furstenrecht –
Purchased battery for a special project, powering a small winch. It performed better than expected, has plenty of power and lasting much longer than I anticipated. Very satisfied with purchase.

Perfect fit for Sears 1150 jumpstarter. Couldn’t be happier !
Davida425 –
So far, so good. Only a few months old.
Chad Moser –
works great
Mark Hendrix –
Took old one out put new one in no problemsNow lets see how long it will last
Jack Williams –
I bought this for my Diehard 1150 jump starter that the battery had gone bad and wouldn’t take a charge. It worked great, came fully charged and ready to go. Seems to last longer then the original battery that was in because I’ve used it multiple times in the last few weeks and still at 100% . So in short I fixed my $160 jump box for less then $60.
david longenbach –
fair price
Steve –
Great value. Better AH rating than original. Works perfectly.
cable –
Works perfect in my Sears 1150 jump starter – even though label on jumpstarter said there were no serviceable parts.
J. Cussins –
This is the best battery of its kind I have had. It holds a good charge for an extended period of time with plenty of power! Highly recommend it.
Robert H. Wright –
Very please!
William Curlew –
I used this to replace a similarly form-factored 19ah battery in my 500/1000ah car starter. Fit like a glove, charged right up and brought the 120$+ unit back to life for only 43$. Must have worked great, it got stolen the very next weekend I used it! (Groan!)
rondglfr –
The battery arrived in physically and functionally perfect condition. It was fully charged and ready to go and is now in use.
Robert J. Ball –
what you see is what you get is the exact battery that you see on the screen. My first lasted me 5 years..
George R. Zerdian –
Great Batteries for my Pride Mobility Scooter. I bought a second set of batteries and have a case on order so I will have a complete battery case backup which can be charging with I am using the other.I was hoping these batteries would overcome the problem of going up ramps like those at Disney World Monorail. which when changing trains require you to go up and down several multistory ramps. the 22 AH batteries run down in charge going up a one story ramp with an elevation of 10 feet. but the power returns after you reset the fuse. The previous batteries [I think they were 18AH] took 24 hours to recharge to full capacity, after draining going up a one story ramp. They were also one or two years old with infrequent use.Maybe there is a way to upgrade my overload circuit breaker for the higher 22AH batteries.
Kevin Hoover –
I ordered it for a friend fr his 10 year old Jump N Carry JNC660. Its a great performer that seems to match the performance of the original battery in its heyday. The good price and quick arrival are just icing on the cake.
Floyd Cunningham –
was already pretty well charge. Only took a couple of hours, seems to be holding and fit in my booster just fine.
Mark S Malloy –
I ordered this battery from Max Life Battery Direct based on the 3 reviews I read. The battery arrived in good condition, however I have not installed it in my portable jump starter, the original battery gave out. The Main reason for my review is the customer service interaction I had with Max Life Battery Direct.I ordered the battery on 01-16-14 from Max Life Battery Direct and they indicated the item was in stock at that time. I Checked the track Package feature in my account on a daily basis to see what the status was on the delivery. It was not until 01-24-14 that the item was shipped. I contacted Max Life Battery Direct via e-mail on Saturday 01-25-14. I indicated I was not happy with the delay in the shipment. I received an e-mail from Max Life Battery Direct Customer Care on (Sunday) 01-26-14. The e-mail indicated they were not sure why the delay happened, they were very apologetic, and said the delay was absolutely unacceptable. They then offered me a partial refund for the delay. They also sent follow up e-mails indicating the package is scheduled to arrive on 01-27-14, which it did. I am giving a 5 star rating for the following reasons.I am old enough to have learned the hard way about the little guy always getting screwed and no one cares. So with that being said I did not even expect a response from Max Life Battery Direct about my complaint. Well I was wrong… I believe Max Life Battery Direct went above and beyond good customer service in how they handled my complaint. I am very happy with their response! I will be ordering them from in the future even if they don’t have the lowest price because of their great customer service. If you order from Max Life Battery Direct and have an issue be assured the Customer Care team will take care of it quickly!!Just as a side note I don’t normally do reviews, however Max Life Battery Direct earned my future business and this 5 star review.
