Abstract

A battery includes at least one rechargeable battery cell that is operable to store energy. An electronics unit is coupled to the at least one rechargeable battery cell, wherein the electronics unit is operable to control an operating condition of the battery, and wherein the electronics unit is inoperable when the energy stored in the at least one rechargeable battery cell is insufficient to operate the electronics unit. A detector component is coupled to the electronics unit and operable to determine that the electronics unit is inoperable. A charge discharge component is coupled to the at least one rechargeable battery cell, wherein in response to the electronics unit being operable, the charge discharge component is operable to provide a charge to the at least one rechargeable battery cell through a first charge path. A trickle charge component is coupled to the detector component and the at least one rechargeable battery cell, wherein in response to the detector component determining that the electronics unit is inoperable, the trickle charge component is operable to provide a charge to the at least one rechargeable battery cell, through a second charge path that bypasses the …
