J. Battery capacity required I*1.8 (safety factor) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ AH
Note: AL1024ULACM power supply is designed to work with batteries up to 65AH. Please note, line [I]
must not exceed 36AH. You have to reduce either stand-by current consumption or stand-by time in
order to comply with requirement.
To determine actual battery size please round line [J] to the nearest larger standard battery size.
