Hi all. I have a CyberPower 1500AVR that has stopped charging its batteries. I replaced the batteries thinking this was the issue as the originals were several years old but the new batteries are the same. With the unit on and the batteries connected, I read 20.5 volts at the battery connectors. Not sure if that is helpful or not. I assume this is just what's left in the batteries after having the unit powered on for a day or so. There are no signs of damage on the board aside from some slight heat blackening of red and black wires just above the viper22a ic. The two caps in the photo, circled in red, both have a brown solution on their exterior which I assume is glue and not leaked from within.
I've read other threads where some caps and the viper22a ic were replaced as a fix. Any help would be greatly appreciated and let me know what I can provide in assistance. Thanks and regards.
