Abstract
A cash register power supply system is disclosed which isolates the work system from the battery charging system. A battery charger charges one of two batteries while the other battery drives a cash register. A timer and switching mechanism switch the batteries between charge and work systems at regular time intervals. Thus, the work system is isolated from the house current and the possibility of power surges which can affect the cash register memory.
