A Backup battery is a secondary power supply. It is usually a direct current battery to provide power to your appliance in the absence of main power supply.
Computer systems also have a Backup battery inside the UPS. The devices that use Backup battery normally get its power from a sustainable alternating current (AC) source or from solar cells (DC). The backup battery will give power to your electronic appliance only in the case of main power failure otherwise the battery will charge from the same primary circuit.
