Hi All,
I have an Inverter device connected to 135Ah 12V Battery (Lead Acid) and AC mains input of course. It works fine when there's AC loss. It's set to UPS mode and hence my PC does not restart when there's AC loss.
Last few days I have observed a peculiar behavior
1. The battery is many a times in Charging mode. Even if it's consumed just for a minute of AC loss, the charging time is as high as 2 - 3 hours. Earlier it used to be hardly 5 minutes of charging if AC loss is just a minute or two.
2. Battery is noticeably warm to touch.
3. Even if fully charged and there's no AC loss, the inverter randomly starts charging it again for long period like an hour
The charging voltage is about 14 V and standby is around 13 V.
Inverter has never given low-battery indication yet
Are these signs enough to conclude that the battery is worn out? It's more than 3 years old and completely out of warranty.
Can a fault exist in Inverter circuit causing this behavior?
Thanks
