Answer / markandeya

total number batteries=votage required/votage of indivedual
cell
Ah value of indivedual battery=1.5*current*time(hours)

for an example:
votage required is 240
cell voltage is 12
then we require 20 cells.

if load is 1 kVa time is 10 hrs
we need 60 ah is required

Answer / jagdish raval

UPS KVA= 1. Then KVA= VA/1000. So I=KVA*100/V. If the V=48,
Then I=21. The load of UPS is 21Amp and it have run for 10
Hours, So Battery Capacity should 210Ah.
