  1. Web Customer –

    Fit perfectly as a replacement in my old APC UPS. Time will tell if it holds up as well as the original.

  2. Robert –

    hope it lasts

  3. RLewis –

    Perfect fit, good replacement.

  4. Beaner –

    Great battery with great power to start my mower. direct replacement and it works great.

  5. Aktreker –

    Have had two of these installed since October. During our 46 hour power outage, I ended up using the UPS, a limited amount each time, to power my 65 TV so we could get some news (had zero cell service). 2X a day for about 20 minutes each and we were able to get updates via that method 4.25 times before the UPS shut down.

  6. C –

    I ordered this battery as a replacement to put back in my APC unit. The original battery was very costly. So this one was half the cost. I will continue to monitor the progress on how long it last. Only have laptop, printer, desktop media server plugged into it. So far, so good holding up well.

  7. country boy –

    I had a Cyberpower 1500VA (os so) battery backup that I purchased about 4 years ago at my local membership warehouse store and during the last power outage I found out the original batteries were too weak to run my PC. After some research I found these mighty max batteries that I learned that I could use 23 of to replace the oem battery pack on my cyberpower unit. essentially you replace 1 battery at a time to the OEM wire harness, optionally use some packing take to tape the two batteries together into a single ‘pack’ then slip it back into your battery backup and plug it back into the units connector and that’s it – battery replaced. So far it seems to work well but only time will tell the longevity of these batteries.

  10. Richard R Kazmierzak –

    This battery went into a small UPS, it worked great, it is half the price of the original battery. I can not speak to how long it will last as I just installed it.

  11. Marin Digital –

    I’m able to get 3-5 years on these batteries in my UPS.

  12. Steven C. –

    The battery is working fine. The price is good and we got it fast. Time will tell if it holds up.

  13. Comprador –

    This is a replacement battery for an APC UPS and was much less expensive than buying a replacement from API. It is made in China, but so was the original API battery.

  14. sarai virgili –

    works well

  15. It’s super effective! –

    Decent replacement UPS battery. Not like these type of batteries are advanced to begin with so… Works fine so far.

  16. ShadeTree Mechanic –

    Works fine — hopefully it will last as long as the original did (over 5 years)!

  17. David –

    Fit right in and plugged right in, was already charged, back in business.

  18. FPM –

    Would it fit in the battery space in my Energizer UPS? Yes, it did!

  19. Frederick P. Mcatee –

  21. M. Stephens –

    Took only minutes to install, works like a charm.

  22. Tom Sargeant –

    Perfect fit, works great

  23. Tom Sargeant –

    Perfect fit, works great

  24. Robert F. –

    Installed this in a battery backup for my LED front porch and driveway lights

  25. ZIM OLSON –

    Tired of buying replacement UPS . Price keeps going up. Batteries keep wearing out. In desperation looked to and found this. Wife now has a brand new UPS in her corner office. Working for number of months now.

  26. Jack H. –

    Too bad I took a month to get around to installing the battery; 1 year warranty doesn’t cover me anymore. I’ll be buying a second battery and hoping it lasts longer than this did this time.

  27. GEH – Worthington –

    HIGHLY RECOMMENDED. EXCELLENT

  28. GEH – Worthington –

  29. Robert G. Wolff –

    fits like the original and does its job.

  30. Richard L. Moreland –

    Putting new batteries in a UPS backup is a very cheap way to bring that unit back to brand new. New battery lasts 3 to 5 years and about 20% of a new unit. thanks, rich

  31. Web Customer –

    Well packaged, 30 second replacement – UPS is good as new again!

  36. Len –

    I FOUND THIS BATTEY TO BE A WELL MADE BATTERY AND PRICED WELL BELLOW THE COMPETITION.

  37. Robert Matcham –

    For the cost of this battery, it performs as well if not better the the Brand named battery it was designed to replace. Do not hesitate…go ahead and save your money and buy this battery.

  38. Phil –

    The fit is perfect, and the battery seems to work fine (just installed and tested) I wish that I had read that it has T1/F1 terminals since the original battery and UPS were T2/F2. Works, but not the best connection to use mismatched connectors. My fault for not seeing that but the terminal difference does not make the battery an exact replacement, only an acceptable one.

  39. Samuel bryan –

    Very good & fast service.

  40. Richard Morin –

    Perfect fit and performs like new.

  41. Peter –

    My APC battery expired a few weeks ago. I found a replacement battery on and received the Mighty Max within a few days. It was identical to the old battery. Simple installation and the unit was online again! I highly recommend this battery. I has been running for a few weeks with no issues. This is a great five star***** product. Highly recommend

  42. Stan Zborowski –

    Perfect replacement for the original battery. Very happy with this product. I would definitely use them again.
