Answer / s p sharma

Load is always in amps. Storage capacity of the battery is
in AmpereHours. mSo if we have a battery of 150 AH and we
are drawing a load of 1 KW with 5 Amps as load then it will
give you a backup of 30 hours i.e 30 x 5 = 150AH.

Answer / k.prakashchandra

AH represents the stored energy which is equal to V
(battery)*AH watt hrs.
