    Not easy to install in my stairlift and did not solve my problem. Have called for service. Needed to change the batteries so I have no complaints about this product.

    Bought two of these batteries to see if I could get the Bruno Stairlift my house came with up and running. I was able to replace the old batteries with these and the lift worked with no issues.

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!
POWER PROVIDER!! Love It.
