My CyberPower 1500AVR endured after a long power instability in the past weeks, must have been on the way out. (about 7-9 years)The batteries no longer held a charge nor the UPS were charging them. Batteries are about a year old, but they are good and holding charge from an external SLA charger.
I found thread 785895 and it helped determining what components were damaged.
On this unit the charger circuit just got overheated to and extent I could not see was components where what.
Like I wrote in that thread the traces are in good condition and the UPS was powering up and providing protection until the batteries no longer held a charge. Because this board is hard to get a replacement, I was thinking of repairing the section that got damaged by removing the components and filling with epoxy resin and re-drilling the holes. Also I have a stock of capacitors that if all works the ones on the board will be replaced.
I like this unit better than the new model. I think it can be accomplished. Opinions Welcome.
