  1. pbpvol

    Works just like the super-expensive battery AT&T wanted to sell me when the other one failed. My son installed it for me in 5 minutes and so far, so good. I guess I won’t know for sure until the electricity goes out, though. When that happens , if this battery fails, I will write a follow-up review. So if there is no part 2 of this review, you know it works! 🙂

  2. Front & Center

    I am pleased that the battery’s physical dimensions were right for the Belkin Battery Backup unit. Installation was quick and true to what the instructions stated.

  3. Bruce Andrews

    Replaced battery that had been in service many years. They DO wear out, you know! Installation was easy – I looked online for instructions (I don’t remember the URL). Back in business.

  4. Johnnywisc

  5. bonny o.

    Very good

  6. Roger J Owens

    Battery works fine. As it turns out my Bellingham UPS was defective. Be aware this batter is non-returnable.

  8. William Bowman

    UPS was beeping. Needed new battery (10 years old). Quick to get, price good, easy to replace battery.

  9. Randall W.

    These seem to last about 18 months. Not great but twice as long as others I’ve purchased.

  10. AaronHe

    Very easy to install; took mere seconds. Working great after one month; I tested it on my 27 Mac too.

  11. SW

    This is my second time to replace this battery. Seems to last a couple of years and then dies.

  12. Dona C

    Easy just unsnap and slide out disconnect. Replace reconnect, slide back snap cover back.

  13. Marla A. Le Blanc

    This battery was a great replacement for my AT&T Belkin Battery Back-Up Unit Rev B. The company and their customer service dept were great and responsive to my inquiry and questions. The battery is a little difficult to replace, as the connectors on the unit itself were difficult to remove from the old battery. I would definitely order from this company again.

  14. Chingas Lee

    Great price. Fit and works fine. True test will be useful life.My Gateway UPS backup has 1/4 terminals and this battery has 1/8 terminals but it worked.

  15. Harold R. Noblitt

    Delivered on time . Replaced Belkin Backup Battery.

  16. PHILIP M.

    My Belkin AT&T Uverse battery died after 9 years of usage. After researching this replacement battery online, beat all of the competition. It arrived safely and it was easy to install. Definitely worth the money vs. buying a new unit

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
