if we want to increase the back up time of an UPS what
should we do ?
if we want to decrease the charging time of a
battery/batteries attached with the UPS what should we do ?
Answer Posted / khaleeq us salam
if we want to increase the charging of a battery first we
have to make sure that the battery have enough AH. then we
should know that there is a internal circuit in a UPS. we
can increase the charging time of a battery through that
circuit.
