Abstract
A circuit for conditioning a battery having a casing and battery charging terminals for charging the battery from an external power source. The conditioning circuit is preferably contained within the battery casing and comprises a discharging circuit for discharging the electrical charge of the battery and a switching circuit coupled to the battery charging terminals and to the discharging circuit for automatically selecting between a first state, disabling the battery charging terminals from providing charging access to the battery and coupling the discharging circuit to the battery for discharging the battery as long as the battery voltage is above a predetermined voltage level, and a second state, disconnecting the discharging circuit from the battery whenever the battery voltage is at or below the predetermined voltage level and enabling the battery charging terminals for providing charging access to the battery.
