ABSTRACT:
A power supply circuit is provided for a battery powered real time clock in a microprocessor based computer system. The power supply circuit monitors the output of the original battery and provides a warning indication when the battery output begins to drift or fade. A replacement battery may then be connected to the circuit. The circuit then substitutes power from the replacement battery for that from the original battery.
