Abstract
An apparatus for minimizing self-discharge of a smart battery pack is provided. During initial storage of the smart battery pack (), prior to be being charged, a self-discharge protection circuit () disables smart battery circuitry (). A minimal current drain is maintained while the smart battery circuitry () is disabled. Upon coupling of the smart battery pack () to a charger, the protections circuit () enables the smart battery circuitry (). Battery packs having to be shipped with partially drained cells as part of shipping precaution requirements are no longer faced with the additional drainage problem previously caused by the smart battery circuitry () during storage.
