  1. frank argondizzo

    Works for the application

  2. Charlie

    Fit my APC UPS exactly.

  3. S. Sobel

    The battery I replaced with this one lasted 6 years. This battery lasted less than 2 before my FiOS ONT declared it dead. I know the warranty is only a year, but I would hope for more.

  4. Robert K.

    Shipped fast, correct fit and easy install

  5. Fixesall

    Appears to be a good product for the money.

  6. Frank

    I am not sure how to evaluate this battery. The last one I purchased lasted almost 6 years. I purchased the same brand again. Price was competative; it was easy to install; no issues.

  7. Kimberly Brow

    Worked good

  8. James F McLear

    Bought the battery and it only lasted about 5 months unfortunately. Batteries come with a one year warranty so I sent a message to the seller about the early demise. He responded immediately and without hesitation sent a new one in the mail. Installed it and everything works fine again! Excellent customer service, hopefully this one last a little longer.

  9. Sherry L. Pratt

    Excellent product at a reasonable price!

  10. Pamela R. Carnovale

    Have bought this a few times. Some lasted one year and some lasted longer. Wasn’t able to charge as advertised.

  11. Betty Davidson

    Exactly what I was looking for!!!

  12. Sadao Sasaki

    I’m happy with the value it provides

  13. Bro

    Direct replacement for my Verizon Fios backup battery. The beeping has stopped!

  14. Ignatius Rodrigues

    For Frontier internet box

  15. George

    Works in FIOS system at a good price.

  16. BMcNeal

    I purchased the Mighty Max Battery (MLB-12) because I have a UPS (Uninterruptible Power Supply) unit which as far as I can tell only needed a new battery to be functional again, so there you go. After receiving it yesterday and fiddling around with it a bit (it didn’t seem to want to fit back into the UPS as it should, despite having the same dimensions as the battery it just replaced) it eventually slid into place. Then I plugged in my various devices (a desktop computer, some external drives and monitor, etc) into the UPS and connected it via USB to my computer (so I can see it’s state of charge). And so far things seem to be working just fine. What I like most about the Mighty Max battery (MLB-12) is that not only does it come with a 1-year warranty, you can extend it another three months by registering your purchase with Mighty Max. Sounds like a no-brainer to me.

  17. Kevin McCauley

    Easy to install, good price

  18. Matt S.

    I’m so glad I found this because it’s so much cheaper than paying Verizon to send someone to change the battery.

  19. Todd Thompson

    Works correctly, easily installed.

  20. Kurt G.

    Cable company would charge service and part for the battery and alarm driving us batty. Part came quickly and plug n’ play good to go!

  21. James denning

    I love the price and great battery.

  22. James denning

    I love the price and great battery.

  23. Jim Palmer

    Purchased battery in October and 3 different times I have gotten a low battery alarm. Since I am unable to return the battery I am stuck for the purchase. This was my original impression, but I sent an email describing my problem and the customer service dept worked very hard to resolve the issue even though they did not have to. Borrowed a backup battery from a friend who has the same backup system that I have. His worked for 2 weeks with no problem on my system and mine worked on his system. Swapped them back and mine failed once again. Tried reinstalling the backup battery and it has worked ever since. Called customer service and they said if there is any problem within a reasonable amount of time to call and they would be happy to replace the battery.

  24. Brent Eiler

    Needs replaced after 5 months… not a good product.

  25. Audrey Lelyo

    The size of the terminals were too small. I could not attach the battery. I needed additional terminals which took 2 weeks to arrive.

  26. William R. Delp

    I got this battery to replace the battery in my Fios box. the battery is used for back up in time of power failure. It is an exact replacement and fit perfect. A can’t speak of longevity I tested it before installing it was at proper voltage out of the box.

  27. Stephen D

    This is my second replacement battery for my APC UPS. The previous battery lasted about 2 years. That, as far as I can see, is the useful life span of this type of battery in this application. It was easy to reference for purchase (this battery is a common size used in many applications besides mine). The cost was reasonable. I do have to say that it took longer than expected, but that didn’t cause me any grief.

  28. Web Customer

    Can’t attest to the longevity but the price was better than Verizon and it works great

  29. KitPerry

    Lasts about two years, very easy to install. Used for the wi-fi battery backup in the garage.

  30. Customer

    Can’t attest to the longevity but the price was better than Verizon and it works great

  31. Kat

    I purchased this for my Frontier FiOs system. So far it has worked perfectly. Although I haven’t had it very long, if it lasts for 12 months like a battery I purchased from a chain store, I will be thrilled. This battery cost half the amount as the one from the chain store. When the time comes, I will definitely purchase this again.

  32. Ron Rusin

    Product was reasonably priced and easy to install

  33. JIMMY THONPSON

    For my father’s stair lift. 2nd set of batteries I ordered over the years. They last about 4 years each

  34. Web Customer

    Battery last a little over 1 yr before I needed to buy another battery,

  35. Kindle Customer

  37. Spring

    Battery pretty much died in less than a year

  38. Robert Harris

    My last battery identical to this one lasted 4 years. The original battery I was replacing lasted 8 years. Shipping took longer than expected.

  39. J. Lo

    Easy purchase and the install was a cinch!

  40. Aruba

    came on time and was a generic replacement for a more expensive battery

  41. Web Customer

  45. Gerald Fierst

    Seems like a good deal. I’ll see how long term durability works

  46. G

    Easy to replace, works well. Verizon charges you 5x for the same thing.

  47. LMZ

    Used it to replace backup battery on a Verizon Fido’s box. At this point in time, can not speak to longevity.

  48. ssteven22

    It worked just fine and easy to install, but it now needs replacement again 11 months after installation. The original battery this one replace lasted almost 4 years.

  49. AB

    Worked for all the time I had Verizon.

  50. AB

  51. Kathy Ellis

    Great product for our project.

  52. Patrick Huynh

    Came in as expected! Used to replace the Verizon FiOS battery.

  53. DINO

    IT FIT THE PLASTIC ENCLOSURE THAT MY OLD FIOS BATTERY WAS IN.

  54. Steven N.

    Easy to install. Fits just like the original.

  55. Garnet1

    The product was as described. Just wanted it faster than I received it. I don’t know about longevity, becauseI haven’t had it that long. Hopefully it will last for at least a year. I would recommend if you need a replacement forthis type of battery.

  56. Lori B.

    Fits fine

  57. John G

    I purchased this for a friend. It was the correct replacement for the back up battery in the AT&T cable box. Only time will tell if it is as good as the OEM.

  58. John M. Wood

    Great product at a reasonable price easily installed.

  59. Luis A.

    The product works well, I’m using it as power backup

  60. Piixel Pusher

    This is the second replacement battery I’ve bought for a really old UPS. Fits perfectly, works fine. Why spend $100 for a new UPS when it’s so easy and painless to replace the battery. The last one served for 3 years or so, so I’m happy.

  61. AARON

    Excellent replacement battery, exact fit and perfect function.

  62. Ronny Vikstrom

    Very good value for the money

  63. Customer

    Very good value for the money

  64. Kosta S

    It worked for me 17 months – more than others mentioned. Verizon sells for $40 and it works 6 years, this is $20, and it’s worry-free for one year. Do the math.

  65. Mary Lou Bissaillon

    Easy install. Works just as it should!

  66. M. Alexander

    My Verizon box needed this replacement battery the price was double from Verizon the price was affordable and it’s working great

  67. Karen H

    Just what I needed to replace a dead battery to my VOIP system!

    No problem with a battery.

  70. PDS

    Works great in my Fios unit. It’s my second one. First one lasted several years even through some long winter power failures. A great deal.

  71. J. Staton

    Awesome product!! Fits perfectly.

  72. Robert

    Good fit

  73. David Ruggio

    Perfect fit replacement battery. Thank You!!

  74. Jim

    Works as advertised….so far.I would like to see how long it lasts compared to my previous battery before giving it a more positive review.

  75. David Ruggio

    Perfect fit replacement battery. Thank You!!

  76. BR

    This battery worked fine for about a year exactly, and then the FIOS box started beeping again. I was hoping for longer life.

  77. Steven E Dement

    WorkI had to replace the battery in the Verizon Fios power supply. It is there in case of power outages so that the phone will still work for a period of time. Plus, Verizon wanted twice as much

  78. BR

    This battery worked fine for about a year exactly, and then the FIOS box started beeping again. I was hoping for longer life.

  79. cheryl romano

    Service was fast. But I’m just wondering why I needed to order another one after only one year from the last one. The back up battery that came when I started the Fios service lasted 2 years.

  80. tony

    Perfect replacement for FIOS battery. Simply remove the old battery and put this one in its place. Works fine. Came charged and immediately after installing it the signal to replace the battery stopped. Quick shipment and good price.

  81. Raymond J. Colombo

    Perfect replacement for the FIOS supplied battery.

  82. Gary DZ

    My motorcycle batteries last 2 years—period. Even with a good trickle charger. I have tried several brands. I usually squeak out 2.5 years at best and replace it the 1st time it doesn’t start. Usually while it is still in my garage. At this price—I will replace them as soon as they show their age. I have now used this brand for 2 bikes and am very happy with the quality.

  83. Edward Herbst

    Great replacement for my Verizon backup.

  88. Marc H.

  91. DMD

    Works fine

  92. uBreakIt iRepairIt

    Good replacement battery like everyone else says. Used this to replace the battery on a Peg Perego Polaris Outlaw. I put zip ties on it to create a handle for removing/replacing it into the vehicle.

  93. Ricardo B. Telemaque

    Great

  94. Robert LiCalzi

    The product was a great price and worked just as well as the overpriced one by the cable company!

  99. J. Cocuzzo

    Installed 9/8/16 – beeping for replacement 4/13/18 so less than two years of life

  100. Tommy

    tested it when it arrived, actually tested higher than rated! works perfect. (tested at 9AH)

  101. nicki

    It fits, it works, no more low battery beeping every month!

  102. James Phillips

    Good price, works fine

  103. New Jersey Homeowner

    Seems to work as a completely compatible replacement for my existing Verizon FIOS battery, and at half the amount that Verizon wanted. Assuming it has the same life as the last battery (about 5+ years), it will be a great choice – of course I won’t know the answer to this question until many years have gone by!

  104. Earl

    Quick replacement for my Verizon Fios backup battery.

  115. BloomingAzaleas

    Fits in the Verizon FIOS power supply unit as advertised. Second replacement battery since FIOS unit install. Prior Mighty Max battery lasted about 2 years before FIOS unit indicated replacement needed. Expected about 3 years.

  116. Odessa Dave

    Replaced the battery in my FIOS system that normally lasts about one year. The local battery store wanted near $50 for the same battery so very happy to have found this battery. The dimensions matched the previous battery perfectly and took about 1 minute to install. The battery arrived quicker than expected.

  117. Dave B.

    Cheaper version of the Verizon battery, but seems to work just as well.

  118. Chuck08854

    Product was delivered on time. Fit perfectly and performance to date has been as advertised. Would recommend this product and company to family or friends.

    Ordering was easy, delivery was fast. It’s a battery. It works as intended.

  127. J. W. Hancher

    It’s a battery. Nothing too exciting for me to give it 5 starts. Seems to work fine ever since my Verizon Fios box started beeping to replace the old battery unit. Happy with the purchase.

  128. Don D

    Just a perfect product for an intended use. I installed this battery into a Verizon FIOS box as the original battery would not charge. The Mighty Max Battery was a perfect fit, connected without issue and quietly went to work, keeping my FIOS operational.

  129. Daniel Miller

    Worked fine, but didn’t even get two years out of it before I needed another.

  130. goldbond70

    Upgraded to a touchscreen and really needed the extra capacity. Perfect fit in enclosure.

  131. Michael L. Yap

    It needs an installation procedure.

  141. Jesse McCain

    It worked for my FIOS box for 19 months before it started beeping again. I’ll spend a little more for the one with the 3 year warranty this time around.

  142. John Larue

    The battery fits its slot and seems to function. I have not had it long enough to determine if the battery lasts.

  148. Tommy O

    i just got it, so all i can say is it fits perfect and appears the same as original. the alarm bell stopped. i have know idea how long it will last, i hope many years.

  149. S. Carmody

    I bought this for a Verizon FiOS battery backup. It worked fine, for when it worked. It has a 1 year warranty, and mine lasted 1 year, and about two or three weeks. So it’s just OK. If it had died prior to the year mark, I would have rated lower; if it lasted as long as the original (3 years), I would have rated it higher. Fit is snug, just a hair bigger than the factory original battery – not a problem except to take 2 seconds more care installing.

    The hardest thing about this battery change was figuring out how to open the Verizon wall box! But the battery change out is straight forward and the replacement is an exact model for the replacement. And I saved a service call of $75 plus the part!

  162. John Hopkins

    Battery is fine, but for fios, just disconnect the old battery and then reconnect. You probably don’t need the battery.

  163. [email protected]

    Leads were not exactly the same size as the Verizon version so it came loose many times over the 1.75 years that it worked. Yep. Worked 1 year 9 months. Seems like it should have lasted longer. Now it won’t recharge anymore.

  175. James T.

    I just installed a new Mighty Max in the FIOS panel today. I got two year’s of use out of the old one; actually it started beeping a few months ago. I unplugged it, wait a minute or so and then plugged it back in, it would run again for a few more weeks with no problems. When it starts to beep again, I just repeat the process and it would run again. I probably got three to four more months of life out of it. I just got tired of unplugging and plugging it so it’s time to put a new one in. We’ll see how long the new one will last.

  176. Daveydoo76

    Stopped that beeping from the FIOS box and went in easily!

    Had to replace my fios ont battery. This one fit perfectly. The original lasted 4 yeaars. Hopefully this one does the same. Came thru packaged really well. Had no trouble installing. Remember to unplug the fios power supply first. There is a short time lag till the lights come back on after unit reboots.

    Identical except for markings. Fit perfectly, much cheaper than ordering from FIOS and faster delivery. Another great experience buying from Mighty Max Battery.

  190. John Barron

    So far so good with this battery. The annoying beeping sound on my FiOS box is gone. Installation was easy, and was much cheaper than the price Verizon was offering.

  191. Robert Birnbaum

    Battery was delivered as expected and is functioning properly.

  192. F.White

    So, far so good. To me least expensive is just as good.

  194. Ed

    Battery is what i needed, however I feel like i was ripped off by getting a second battery that i didn’t want. One order came back as declined. So i purchased again with another card. I was charged for both. The shipper promised a refund if i paid to return the battery. Shipping cost was more than the battery cost.

  202. Rick Richardson

    This battery works perfectly for replacing the Verizon FIOS power backup. That annoying beep will continue until you replace it so get one of these ASAP!

  203. Cory Rhoades

    This worked great as a replacement battery for my FIOS box. Just remove the old battery and plug this guy in.

  204. Rick Stein

    I was expecting the previous Mighty Max battery to last longer than 12 months. I’m giving this battery one more chance. If I need to replace again in 12 months, I’ll look elsewhere.

  205. 6Toria

    The battery came quickly, it took mere minutes to install, and my internet was up and running again. It was a perfect fit.

  206. BUGMANN

    It has not been much time since I purchased this so I have mo comment on its endurance. The factory battery died b4 end of yr 2. You do need to remove the adapter connected to original battery so this one can get connectedBUG

  226. Jimbone

    This was a perfect replacement for a drained Verizon backup battery. For the longest time I had to put with the piercing beep whenever the original battery drained. I got around by unplugging and re-plugging the terminal which seemed to quiet the thing until maybe six months later. I called Verizon thinking they would give me a free replacement. Nope , they wanted $80. The ML8-12 sells for $20 on . It’s a no-brainer really…Update 2/2020: Average at best. Drained after 3 years. Had to buy a different brand replacement while I try to recharge this

    Purchased for a FIOS battery back up system about a month ago. The original lasted ~ 4 years. The first replacement batter we purchased (not this brand) lasted just shy of 2 years. I’m hoping that this at least meets the original battery’s life of 4 years. Stay tuned. So far, so good!

  234. Mark R. Skokan

    The battery has been in place a couple of months with no issues. Can’t speak for longevity, but so far so good.

  241. Liking Shoping

    I had to look several hours before I found this battery because the battery is used with the Frontier Backup battery for their FIOS lines. This actually works great. I put it in a year ago and have not had a problem.

  242. M. B.

    Installed 03/ ’17 and It went out 03/’19. It did last 24 months. The old Gold Top battery lasted 3 years but it costs twice as much. So, it depends on what you want. To me The Mighty Max is a good buy but it only has a 12 month warranty.

  246. Web Customer

    Works great to replace the battery that was in my Fios/Verizon ONT box. The only thing is that it doesn’t have the connecting wires that plugs in from the battery to the ONT box. Luckily I was able to disconnect the wires from the old battery and plug them in to this battery. It’s working great so far but I’ve only had it for about a month. Hopefully it has a long life. *update 11/16/17- beep beep beep. The beeping has come back. I got this battery back in April, so it did last about 7 months. Disappointing as I had lived in my apartment and the battery previously purchased didn’t beep for almost 3 years. Meh, you get what you pay for.

    Beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep…New Mighty Max Battery…NO MORE BEEP!What more is there to say? My Verizon Fios box battery was on it’s last leg, beeping every 24 hours, and after months of daily pressing the override button, I had enough. But when I contacted Verizon to purchase a new one, I almost choked at the price! As usual, I turned to .com to see what was offered at a more reasonable price. I decided on this battery after reading reviews. The battery arrived in good condition, I read the instructions, switched out the battery, and viola…no more beeping. It really was very easy to do. The hardest part was getting the Verizon Fios box open! It has only been a few days, but for now, I am very pleased with the purchase and should have ordered it months ago!If anything changes, I will update this review.

  353. D. Harrison

    This fit perfectly into the FIOS control box and was recognized immediately. I followed the instructions on the FIOS website and unplugged the box before I swapped batteries and did not have to anything for it to come up. The FIOS battery lasted about 3 years and is a user-replaceable item. I suppose if you want to pay a lot, you can get a Verizon tech to come to yout house and replace the battery, but I suspect it would cost a lot more than the under $20 this battery costs. It took about 5 minutes to change the battery, double-checking myself the whole way through. Next time will probably take 2-3 minutes. The power terminals are a little shorter than the original, but are in the same positions and the power connectors fit on them properly. If you are capable of undoing a piece of Velcro, holding a 3-4 pound battery, slipping connectors terminals off, then slipping the terminals on the new battery following the red/black color codes, you can do this yourself.

    Seems to be working just fine. It’s hard to tell how it will do over time, but this ended up being the battery I chose for the power supply for my AT&T gigabit optical network terminal. When I unplug the power supply, it switches to battery and continues to supply power to the optical network terminal. Only time will tell as to how long it lasts.

  383. Random shopper

    This did the job of quieting my Verizon FIOS battery backup, which was squawking every 24 hours or more often for a fresh battery. Much more reasonably priced than buying directly from FIOS. Easy to install. It’s only been in for a few weeks, though, so verdict is still out on how long it lasts.***11.5 months after install*** Battery beeping is back and I’ll have to replace this battery. It’s within 1 yr warranty, but warranty info is NOT available online and fighting with the manufacturer will cost me more in time and sanity (beeping in the background) than new battery. Unfortunate, but reality. Will buy another and will hunt out warranty information at the beginning so that when new one goes down within year, I’m ready for the battle.

    The box in my garage started beeping. This battery made it stop beeping! I have a FIOS box in my garage. I have no idea what the box does, but all of a sudden it started beeping. All the time. So very annoying. The replace battery light was lit, so I did that. This battery replaced a black and yellow Goldtop HG GT12080-HG Long Life, Rechargeabe Battery. It worked. The beeping stopped. It was easy to put the battery in, there is a little wire that attaches to the battery and that’s it. No more beeping:)

    Great drop-in replacement for the battery in my mother’s FiOS system, at something around half what Verizon charges if you buy one from them.

  447. J. Tran

    Perfect replacement for FIOS battery. If you go to the Verizon website and watch the video for installing the battery, it does an excellent job of showing how to do this. Just unplug the old battery, making sure to keep the old wiring harness as well. Take the cap off the new battery and plug in the wiring harness and then install the battery into the FIOS box. Everything is either color coded or keyed for proper matching.

  448. Melissa

  457. B. Klein

    The battery came quickly. It was the right battery to replace the Fios back up battery . The battery was half the price and was installed by myself in five minutes. So far it been performing like the original and I have no complaints. This is an update. Since ordering this battery in April 2016. I have had to recharge it using my car battery charger twice so far. Unless there is something wrong with my equipment this battery does not stay charged for very long and I am not getting the years of service I had hoped to get from it. I would not buy this battery again

  458. RCW

    Works great no problems at all

    Less expensive replacement. Works fine.

  460. David Down

  461. RB

    It works great, but I’ve only had it for a month. If it stops working at any time, I’ll update the review. I bought this instead of Fios’ $50 replacement battery. This was a great price ($18.49) with no shipping charges. I ordered it on Saturday and received it on Wednesday. Oops, maybe I’m leaving too much of a seller review here. Oh well, I’m leaving it. It shall be known!UPDATE: The red replace battery light is lit on the Fios BBU. This battery didn’t even last four months.UPDATE: Upon closer inspection, one of the cable attachments on the battery had come loose. I actually needed to cut off the casing around the metal attachment, and then use vise-grips to keep metal touching metal. But once I did that, the battery was absolutely fine. No longer is the replace battery light on. So I’m now changing my review again and giving it four stars. For me it wasn’t that hard to fix, so I only took away one star. I’m writing this on 9/4/16, right about four months after installing it. I’ll update again, if necessary.

    Reasonable price for the FIOS backup battery. This is my second battery. It worked fine. I had a problem having the FIOS system to restore after changing the battery. The FIOS tech told be that after removing power and the battery plug, wait 6 minutes before pluging in the new battery and restoring power cord.

    Bought this to replace a battery in Verizon Fios box. I still don’t understand the need for the back up battery. I don’t believe we’ve actually used it. It’s probably just a way for Verizon to scam more money. This battery was less than half the price of the one Verizon sells. Made the beeping in the box go away-I’m happy about that.

    Verizon charges about $50 for their battery. No way! I decided to take a chance on this one. I realized that the quality of this battery would not be tested until a power failure. Well, about a week after I installed the batter, we did have a power failure! The battery made it through the ten hours without power and is still charged. No problems. And half the price that Verizon charges. Highly recommended!

Same model fits in each of our four wheelers great product
Replacement for my Murray MT100 riding lawnmower. Murray does not make replacement batteries and you are on your own if the battery goes bad. Bought Murray MT100 in 2023, battery went bad in 1 year and all other Murray replacement batteries are LARGER so it won't fit.This Mighty Max Battery fit the MT100 fine and it starts it perfectly too.
Direct replacement for generac portable electric start generator. Works great.
Received really quick. Boxed well and fit great. Worked like a charm! I would definitely recommend this battery.
As an athletic trainer I rely on our water units every day to provide the water to our athletes. We have over 900 student athletes enrolled, and these units get used daily, so it is imperative these batteries are reliable. On a side note, I also use these batteries on my fishing kayak to power my fish finder. I can use my fish finder for about 20 hours before it turns off. These batteries are great! Highly recommend. I have not had any issues so I haven't spoken to customer service yet, but if they are as good as these batteries have been, I think I am in good hands.
Needed a replacement battery and the manufacturer wanted $50 whereas you only required $20. Made it worth it!
satisfy with price and easy installation.
Arrived in great condition comes with the bolts to attach the wire over all very satisfied
