Is my UPS Battery is Faulty?


#1

I purchased New Desi UPS and Excide 180 Plus Battery.
I was checking Battery constantly with Multimeter.
UPS cutted Battery from charging around 14.3 Volts.
But battery voltages drops with in 3 hour from 14.3 to 12.58.
And it ramained on 12.58 Volts.
Is battery is faulty?

Your battery is OK. During charging, battery voltage goes up beyond nominal 12 volts to 14.5 volts or even higher, but it drops in a few hours to roughly 12.6 volts if charging is stopped.
