Hi Folks
I have a APC BACKUPS-RS550. This was lying idle for over a year. Now when i checked it was not working (no power). Checked the battery and found it to be dead( zero Volts). So i replaced it with a new battery.
Now it powers on and functions properly, but the battery does not charge so the UPS works till the battery voltage falls and then dies. I need to figure out why it is not charging. I checked the onboard fuses and it seems fine. The caps also dont seem to have any issues (atleast visually). can anyone help identify why it is failing to charge.
The pic of the PCB is attached. Any adivce on how to troubleshoot the issue ?
