I bought an APC UPS ages ago, cheap. The batteries were stuffed and
when replaced it worked fine. Until the batteries died again :)

The most obvious question is... have you checked the batteries? They
seem to be reliable units and as APC charge a fortune for replacement
batteries most people just replace the whole unit.
