  4. Randy C. (verified owner)

    My first shipment was lost in the US mail. I had to call in to get the second one shipped. Waited a total of 17 days for my battery.

  5. CoconutGrover

    Good for my alarm system

  6. H. Tsang

    Went online to search for replacement instruction. Found this voltage and size matched the one I got. Installed it and everything is working so far for almost three weeks. There was a storm that knocked out power in between. My UPS system shows estimate 89 mins of power, after two hours it still shown estimate 79 mins of power left. So far that proven the battery is working and better than I expected.

  7. Ray

    Installed as described in my cyber power supply. So far works great. No issues.

  8. Web Customer

    My UPS started to beep, quit working. I replaced the existing internal battery with this one. Just plug ad play, UPS is happy again.

  11. Michael HathawayDan The ManDaniel V. NovatnakscatrBraindKristinM. SanDukie564DCMeganMartin Chenier

    First one we got was dead. They shipped a new one and it works great in our APC battery backup for our barn monitoring system and computer! Excellent customer service also!

  15. T. Hogan

    Don t know about longevity, have only had it a month. It arrived promptly and easily replaced the battery for my Verizon system. Ordering was easy and with 2 simple steps I increased the warranty to 18 months. Good Deal. Very Happy!!!

  16. Gerald Jackson

    easy install

  17. SJJ

    It runs our lawn mower PERFECTLY…

  18. j. thorpe

    In my opinion, the Mighty Max battery is comparable to the name brands. I’ve purchase 4, so far. 3 for battery backup of our church’s Fire Alarm Control Panel and one for my home intrusion system. I checked the batteries’s voltage with my Fluke meter before installing: about 13vdc. The batteries arrived very quickly and were very well packaged. I’m happy!!

  19. Michael HathawayDan The ManDaniel V. NovatnakscatrBraindKristinM. SanDukie564DCMeganMartin Chenier

    La batterie est exactement ce que j’avais besoin pour remplacer celle de mon APC 500. Fonctionne à merveille.

  20. M. Davis

    Fits old battery’s spot perfectly. Cannot comment about longevity in as much ad i just installed it.

  21. Robert Man

    I change out all the batteries every three or fours years. I been using theses batteries for few years now in all my fire and security devices. They always lasted the time and done a great job.

  22. Steve (verified owner)

    Battery works great

  23. Johneo

    Got this as a direct replacement for a +10-year old flashlight battery (yes, flashlight!) It arrived pre-charged and works great in my 10,000,000 CP flashlight. If this one lasts another 10 years, I’ll have gotten my money’s worth. Thanks!

  24. Patricia J. Aker

    Fast delivery and so far works great

  25. R. & E. R.

    I used this to replace the battery in my small APC UPS and it worked great

  26. Kindle Customer

    Arrived undamaged and a perfect replacement fit for my APC model ES750. The fit is tight but exactly what you need. No problems plugged in for four months so far. would buy again.

  27. Spencer

    Thanks.

  28. clifford

    good product reasonable price

  29. Rico

    Price, quality, and price.

  30. Rennie Mcmanus

    battery is great needed it to replace mine in my Verizon battery back up since they are cheap and want customers to maintain their equipment. but battery was easy to install will buy it again when I need one

  31. Christine

    Easy install for replacement of Verizon FIOS box, exact fit – hardest part was getting connectors off the old battery. Narrower terminals than original battery, but connectors fit securely. Extend one year warranty by three months by registering. From comments appears warranty replacement if needed is easy. Company HQ in USA. Can’t comment on longevity – yet.

  32. J Explorer

    Cannot tell about its longevity yet but so far works well and met the specs for a rechargeable speaker I have

  33. Gragorin

    This fit the bill for my dead UPS battery. It was easy to pull out the OEM one and fitting the replacement one. One quibble is that they did not include a replacement pull tab to remove the battery but to be honest it’s no big deal as I expect this to last years anyways.

  34. Dan The Man

    Purchased this as a replacement for a 2008 model CyberPower 685AVR. Usually got about 3.5 years service per CyberPower branded battery. Due to price and availability I started using these 3rd party units. The most recent MightyMax only lasted 20 months. It also failed differently than previous models which would slowly loose capacity. This one just suddenly quit taking a charge and the UPS outlets shut down. Not the fault of the charger as I tested with another battery and it still works fine.

  35. Kelly

    Great prices and superior customer service. They really care about doing what is best for the customer.

  36. Brian Szymanski

    Exact fit and function for back up power needs.

  37. Steven

    I use it for my fish finder. Keeps a charge for a long time.

  38. BK

    the battery arrived on time easy to install

  39. Walt Daddy

    I bought a CyberPower 500VA UPS several years ago. When the battery failed, I put it to the side. I decided to purchase a replacement to put it back into service. This battery was a good price and it has saved me the cost of replacing the otherwise fine UPS.

  40. Nimit B.

    Works great!

  41. Austin

    Works great for a back up power supply

  42. Swed

    I used it for my alarm system. I have bought Mighty Max Battery’s before, for my lawnmower, and the work excellent. Highly recommend them.

  43. Denyse

    Have not had it long enough to review.

  44. rwz

    Time will tell how long it lasts. It makes no sense to ask someone how it’s longevity and battery is when you just bought it. Their should be a n/a rating for that . I marked 5 stars because i had no other options and did not want to downrate it. The battery came fully charged and all dimensions and terminals were correct 12.8 volts right out of the box. I bought 2 and put them in a chair lift . they worked just fine.

  45. Linda Williams

    It is very easy to install and it works great. Not too heavy to carry. I recommend it to anyone.

  46. detivtj

    Perfect fit

  47. RG@VA

    Drop in place and connect rechargeable battery replacement for Fios box. Time will tell how long it will last.

  48. Grant Fritchey

    We needed a replacement battery for the alarm system. The factory battery cost a fortune. This one is exactly the same in every regard and cost WAY less. It’s been in the system now for a few months and it’s working perfectly. No complaints.

  49. edwin morales

    It did it’s job. Awesome

  50. Shane Mohammad

    Good replacement for alarm home security system battery

  53. justme

    Fits my home alarm control center perfectly! Hopefully it will last!

  54. Art L

    Great replacement for my Verizon Fios box – great value for the money.

  55. Kolt

    I have only used this for about a month to replace a battery on a Samson XP106 speaker. Comes fairly charged out of the box and hasn’t had any issues at all. Inexpensive compared to other batteries but I think it’s more reliable. Comes with a 3-month warranty extended warranty offer.

  56. walt

    Good battery, reasonable price. Used to power game cameras.

  57. Stuckina8track

    Direct replacement for the APC ES500 battery at half the cost.Very happy

  58. Darin Coberly

    A great and solid working battery at a very competitive price 5 stars

  59. Steven

    Great value!!

  60. ML

    Ordered this battery to replace the worn out one in our APC power supply. The APC is older now, and this is its second battery replacement. APC no longer carries the battery, and this one fits and works well. Check the amperage and voltage ratings plus the case dimensions when making a battery choice. If this battery lasts as long as our previous aftermarket battery, we’ll be pleased. Beats buying a new APC unit.

  61. jrod

    great replacement for alarm panels, a good upgrade from the standard 12 volt 4 amp ones.

  62. Terry and Cheri

    Great

  63. DL

    Fit and performance as expected. Charged as directed before use, works fine and should last as long as the OEM battery.

  64. Web Customer

    no complaints at all prompt and accurate delivery! great price

  65. Ben I

    Price was good seems to work so Far Replaced Battery in jump start air device that I’ve used for years. It appeared that there was some acid leaked out during shipment Time will tell if it affects long term function

  66. Adam M.

    Battery lasted 8 months. ONT says “replace battery”. Garbage.

  67. Prime I.

    I have two powered speakers which do not work without a 12v battery installed. Once installed, works like a charm however, once unplugged from wall-jack, they don’t last very long and when you (have to) let them run out for a longer period of time, they… ‘short’ inside and you can throw them out. I did ask the company for their recycle program but never heard back; guess some only want to sell.

  73. Julia

    I have been using Mighty Max batteries for years. The batteries normally lasted longer than expected. However, this time it stopped working after six months. Even though it comes with a one year warranty, I was a little worried because website says 1-Year Promise to Repair! because I didn’t want to ship a heavy battery back to the company for repair. When I contacted Might Max to inquire about the warranty, they immediately sent me a replacement free of charge. The customer service lady was extremely friendly and helpful. Thank you Might Max. I will definitely stay with Might Max for all my future battery needs.

    These worked great for our gate opener.

    My alarm company wanted $124 to replace my battery in my system. I was able to replace it for $19.99 ! This battery is easy to install and if you register the battery, you get an extension on your warranty

  81. robert s gregan

    perfect for application

  82. Michael Hathaway

    I get 5-8 years out of these batteries, (not 4 months). I see people having failures with these batteries because they are not maintaining correctly. Most onboard charging systems will not keep this battery properly charged. You should purchase a Noco Genius 1 at minimum, or better a Noco Genius 5. Set the charger to AGM. A regular lead acid battery charges at 13.8-14.5v, but an AGM will need 14.7v to top off or it will slowly degrade. Once charged, set the Noco Genius charger to 12v repair mode, at least once every 6 months. If the battery becomes completely dead or drops below 1v, set the Noco Genius charger to forced mode and then charge using AGM mode, then repair mode. Do not use repair mode every charge or you may dry out the fiberglass matting.

    Shipped fast. Exact replacement at a very good price.

    Batteries were very strong. Put them in my razor dirt bike and they fit like a glove.

  86. Gordon Meyer

    Worked great for my home alarm system. Took just a couple of minutes to swap it with the old one.

  87. Dave F.

    Great product at a great price. No idea how long it will last but it can’t be worse then the original one. Was purchased to replace the battery in my Ion Explorer Outback portable speaker.

  89. Donna L. Landry

    I needed to replace the battery in my mother’s Stair Assist and didn’t want to pay the $300 the company would have charged me. So I searched Youtube and found a video and sent it to my very handy cousin. Had the battery installed in about 20 minutes. It was a win win!

  90. Harry

    The ML8-12 comes as two separate 12v batteries. The original batteries inside the CyberPower 1350AVR are connected in series using a special adapter plate and tape (see photo).To install the ML8-12 batteries, remove the tape and the batteries will come apart. Be sure to note how the wires are connected (take a photo) and how the adapter plate fits and then disconnect the cables and replace the old batteries with the new batteries. Note: make sure the wiring and battery polarity is correct!Once installed, the CyberPower will immediately power-up because the new batteries are fully charged. At this point you should be good to go. Make sure you put a label on the unit noting the date the batteries were installed so you can use that as a point of reference in case the batteries need to be replaced at a later date.There are some great installation videos on YouTube as well, so search there for additional guidance on the installation process.I cannot speak to the battery life longevity, so you will have to refer to other reviews for a definitive answer on that topic. But the batteries appear to be exact replacements for the original and so far have met expectation for the two months they have been in service.

  91. AZCAMERA REVIEWSTop Contributor: Photography

    I have purchased a few of these batteries for my APC Back-UPS and so far so good. For a 1/3 the price they are functioning as well as the OEM batteries. They are the same size and the connections fit properly. The reason I did not rate the longevity & battery life is because they are new and haven’t gone through their paces…yet. But for the money they are a good investment.

    As about plug and play as it can be to replace batteries in my UPS

  97. David DeVore

    Delivery was fine, however it turned out that my UPS had problems with the charging circuitry, so I have been unable to actually use these batteries. Therefore, I cannot truly post a review on the product.

    I bought two of these to replace the old ones in the house alarm system and the Verizon FIOS box. Pretty straight forward swap. The only thing I would caution is that the metal male connector is wider than what’s on one of my old batteries. I had to buy new female connectors from Home Depot and crimp in the wire to fit them in. The connector size would be helpful to have in the product description. Overall good product.

  109. Dukie564

    worked as advertised

  110. DC

    Exactly as advertised. You will need to solder on leads for use. I used old ones from worn out batteries.
