Abstract
For recovering and reconditioning a smart battery, a functionally dead condition of the battery is detected. The battery includes an electronics unit. The electronics unit is operable for controlling an operating condition of the battery. In the functionally dead condition of the battery, the electronics unit becomes inoperable. While in this condition, a current limited trickle charge is provided to the battery such that the path of the trickle charge bypasses the inoperable electronics unit. Upon the battery receiving a sufficient amount of charge, the electronics unit regains control. The electronics unit reconditions the battery by recharging it to a fully charged state.
