Abstract

See full text

A life safety device includes a battery assembly with a rechargeable battery. Extended shelf life is achieved by annually initiating an over-discharge protection mode in which a battery protection circuit prevents current flow from the battery. The life safety device remains in the over-discharge protection mode until the device is connected to a charging power source at the time of installation. The battery assembly then exits the protection mode and enters its normal mode of operation.
