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!

Ordered as a replacement battery for a 2016 Honda PCX150. Received with a charges which was a nice plus. Battery was fully operational when received and installed. Only issue is in the terminal attachments in that the “keeper” nut would not stay stationary within the battery terminal hubs when trying to screw the terminal to the cable(s). Had to shim and/or tape them in place in order to start the bolts and complete the attachment to the battery terminals. Otherwise appears to be a good replacement battery. Would purchase another when the time comes,

Battery was received from UPS in a beat up box with a lot of dirt and ink stains on the outside of the box. The inner box with the battery was unharmed. This was an Amazon ship and the packaging was not up to their standard.
