5 reviews for 12V 8Ah Compatible Battery for APC Back-UPS ES 750 UPS

    So far it’s working great. This is my second battery from MightyMax for this UPS – I think the first one lasted around 1-1/2 to 1-3/4 years before it starting acting up, and almost 2 years before it really needed replacement, but I used to turn off my UPS every night, which I think may have caused it to fail early, since it might not have been charging all the time that it should have been.
    The price is right in any case, and this time I will keep it on all the time so hopefully it lasts longer!

    Once I made sure the battery was fulling charged, I unplugged the UPS and the new battery kept the commuter on for at least 10 minutes. The battery is a great battery and was received ahead of time.

Great battery. Working perfectly in my garage door openers.
Arrived in one day from Amazon
I purchased the Mighty Max ML7-12 12V 7.2Ah battery on Amazon in June 2026 to replace the battery in my APC Back-UPS ES 550, and it worked perfectly. The battery was very reasonably priced, arrived quickly, and was incredibly easy to install.

The fit was exact, the connections were straightforward, and my UPS was back up and running in just a few minutes. Now my modem and Wi-Fi system stay powered during outages and power flickers, which has eliminated the need to constantly reset my network equipment.

If you’re looking for an affordable, reliable replacement battery for a UPS, alarm system, or other backup power application, I highly recommend the Mighty Max ML7-12. Great value, easy installation, and excellent performance so far!
