Mighty Max 12V 9Ah Rechargeable Battery Replacement for APC Back-UPS XS1500

it'sokay: I've purchased these replacement batteries for APC UPS', they tend to only last a year before APC warns there's an issue and doesn't pass the voltage test and needs to be replaced. They're okay.

Michael R: I received a pair of these that did not appear to be fully charged. The company happily sent me a replacement set and they work wonderfully.

Amazon Customer: Came charged. Easy to replace my original battery. Working ok so far. Just need to see how long it lasts. I bought a second one for my next UPS. Thanks

bjluna: So far so good. I taped the batteries together with duct tape and hooked up to the existing cables in my back up battery unit (APC Back-UPS xs1500). The batteries were partially charged (less than 20%), but charged them overnight and everything worked fine. I've been using the unit for a couple of months and it has not been put to a power outage test yet. The good news is that I have not had to think about the back up battery at all since installing the fresh batteries. It is nice to be able to simply replace the batteries at a fraction of the cost of replacing the back up unit/surge protector.
