Answer Posted / pritam
i think it is not possible because i have already
experimented with that idea if increasing battery ah but
after discharge of battery it is not possible to charge the
60 ah battery with the ups inbuilt charging system as if ups
charging current is 1 ah then it will take 60 hour to charge
the battery.
to overcome this u need to charge the battery by using
external charger and cutoff the up charging process
