how to calculate AH of a battery?

Answer Posted / ravikumar josyula

AH capacity of the battery is the current required to
discharge the battery from its full charge voltage to full
discharge voltage and the time taken to do so.FCV of a cell
is : 2.2 or 2.3 volts , FDV is :1.9v.
If we know the no plates of a battery then can calculate
the capacity as above. Otherwise full charge it and the
discharge it to full discharge voltage.mutiply the time
taken to get fully discharged in hours and the current
drawn in amps.
