Hi,
I've installed a UPS for my house (220V mains), connected with a 12V car battery. In my area the daily power outage is 4 hours, max 1 hour at any one time and UPS remained fine providing backup during this.
Yesterday I noticed that UPS is charging the battery for 6 hours while still charging it and battery is very hot. I opened the cell cover and saw water boiling inside, situation doesnt look good and I disconnected the UPS.
I believe UPS is overcharging the battery and there is some problem in the cut out (when ups should stop charging), so can I fix it by opening the ups? Any one knows if its a simple matter of adjustment?
I am a non-electrical person, have developed some basic circuits of telephone bell, fm transmitter many years ago.
