This is a video describing a common problem with an APC XS 900 back up power supply. The problem starts with your supply having an overload alarm. You reset it and it comes back after a minute or so. Replacing the battery will not fix it as the problem is related to the internal fan not spinning like a new fan. The fan still spins but there is some friction inside and this causes the CPU to think there is a problem and gives the alarm on the UPS supply.
