  1. Jerry Crowle

    perfect replacement

  2. Joe

    Replaced a 5-6YO factory battery with this. Direct replacement. Will see how long something can run once battery is fully charged. The unit I’m using it in doesn’t have a detailed status light but I had it plugged in for 5 minutes and I plugged and it seemed the unit stayed on. I use this with a security camera system so the cameras will run a bit if power goes out.

  3. Yaya

    I just purchased this battery for my ES-550, so will try to update on longevity later. I measured my old APC battery and the case measured 6 X 3-3/4 X 21/2 in. I was wondering if the 4 in. measurement displayed is including the battery poles? Anyway I bought it because it’s far cheaper than original and if it doesn’t fit I’ll keep it anyway as a spare for other 12V gear I have. Also buying because one of the reviews said it fit they’re ES-550.

  4. Aaron

    Fit my model perfectly and wasn’t crazy expensive like the big name brand models it works just as well if not better

  5. shivalm

    No issues with the installation of the unit. Very easy setup!

  6. Craig KC

    Fairly easy to install. Tested and works fine as backup power. Have not checked how long it will power backed up devices yet.

  7. MemTN Dad

    The battery works great. I have an older model APC ES500 and needed to replace the battery. After installing, it says that it should keep everything running for 17 minutes. Much cheaper alternative than the APC branded batteries. I also updated the APC Powerchute software since I was using the version that originally came with the UPS.

  8. Baker

    Perfect replacement for my APC Back-UPS ES 750.

  9. Edna M. Hanson

    Even after installation, the unit still beeps every day or couple of days. It’s a new battery replacement, and we’ve done this before with no issues.

  10. Alan D.

    I expect these types of batteries to last around 5 years, especially if they’ve been drained to near dead a few times (storms and wind can wreak havoc with power where I live). My ES-550 was was starting to fail the previous battery on the self tests. Received this quickly, installed it, let it charge a day and put the UPS back into use. Passes the tests and keeps the devices running. Since I’ve only recently obtained this, I can’t speak to how long it will last for me yet.

  11. Paul Sellers

    Battery came quickly, charged quickly, used in backup for computer, running smoothly

  12. S. Hope

    Haven’t had it that long but it’s working allright

  13. FJLTop Contributor: Cooking

    My husband is building a remote control brush mower, affectionately called his robot. This battery was used in the project and it does quite well.

  14. F. A. Cecere

    Perfect fit easy to install. 2 minutes

  15. Tony

    Installation was easy, it got an old ups back up and running and the price was good. I haven’t had it long, so longevity, I can’t say yet.

  16. Sal1953

    The battery worked perfectly for a replacement to my APC backup. Only time can tell if it has a good functional life but so far so good.

  17. Phil W

    So far still a green light and works fine. Pleased with price, prompt shipping and comparability for my UPS.

  18. Chuck G.

    Easy to set up and is keeping my camper battery well maintained. Very pleased with the product.

  19. Gene Fischer

    Reasonably priced, perfect fit.

  20. $mistreatya

    So far the battery performs as it should, I haven’t had it very long but ,as I said, so far so good! I would recommend this battery!

  21. Demetra T. Rowan

    This was used on an old UPS and was easy to install

  22. DoubleA

    Replaced the original battery with the Mighty Max. It’s been running without any issues for a month. It was easy to switch out. It arrived very securely packaged. I would highly recommend to anyone looking to extend the life of their APC battery backup.

  23. Paul G.

    This replacement for the OEM battery worked fine for me.Note: After installing this new batter I still got a red flashing light on my APC-UPS ES 550 and a notice in PowerChute saying the battery needed to be replaced. However, removing the battery, disconnecting all connected devices, unplugging the APC, and then holding down the power button for around 10 seconds to discharge the unit, before reinstalling the battery, solved that problem.

  24. Ryan Nurmela

    My biggest concern was whether this would work for half the retail cost of the official replacement. It worked!!!!!!!

  25. Michael G. Drew

    Replaced APC backup battery and works great.

  30. J Lock

    It was a easy install into my APC Back-UPS ES 550, It works, the beeping has stopped. Cant comment on the longevity because I just installed it.

  38. George T

    This battery fit nicely into my old APC ES-550. The terminals are the F1 type, a little narrower than the F2 which were on the original battery – but this wasn’t a problem. No complaints!

  39. R. CushmanTop Contributor: Magic: The Gathering

    I bought some UPS from a thrift store and have been replacing the batteries as I bring them into service. This one is an APC Back-UPS ES 550. This battery installed easily and after charging it overnight I put a computer and monitor on the battery side and pulled the plug. It ran fine for fifteen minutes and would have ran longer but I just wanted a quick test.

    Ordering painless, delivered as promised, installation fast, and the product was a perfect replacement. Hopefully I’ll have have several more use from my UPS. 100% uneventful ~ and that’s a GOOD thing!

  45. tspia

    I have 2 APC UPS units (ES500 and ES750) and this battery fits both perfectly. Like the original battery, it is also inconveniently snug for attaching the terminals and slipping into the cases.

    THIS IS 2ND ONE I PURCHASED FOR MY 5 APCs

  54. Robert L. Jesse

    Brought this to replace a battery in a Fios box – not sure why that isn’t Verizon’s responsibility?? Anyway – easy to install and works but evaluation will depend on how long it lasts.

Mighty max brings the battery backup back.
Arrived well packed in unopened sturdy box. Was replacement for identical Mighty Max battery I ordered 2 years ago. Taking 1 star off because didn’t include the needed terminal clips - was able to use the old battery’s clips
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
