Abstract :
In this paper, prevalent use of flooded lead acid batteries as a backup for energy with Uninterrupted Power Supply Systems (UPS) in homes is investigated. An analysis for two different UPS Battery configurations and their comparison with battery life is presented. In one configuration, inverter and battery charger of UPS, which is connected to a battery have good power factors and design. In the second configuration, inverter and battery charger of UPS have poor power factors and design but is connected to the same battery. Based on developed economic model and battery life comparison illegal use of flooded batteries is identified.
