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.

Thanks Dale, Actually its working now off a car battery but still
need a circuit diagram so I can modd it
so inverter runs all time.. These ups's are a cheap source of sine
wave inverters!
