A system and method to identify whether a removable battery pack inserted into a battery-powered device is an authorized battery pack for the device. Battery-powered devices may include a battery-powered drill, saw, flashlight or other type of device. The battery-powered device may send an authentication query to the battery pack. If the battery-powered device does not receive a valid reply from the battery pack, the battery-powered device may verify that the battery-powered device is still within a phase-out period that allows the battery-powered device to use a battery pack with an invalid authentication. If the phase-out period has expired, the battery-powered device may disable the use of the battery pack with an invalid authentication. If the phase-out period is still running, the battery-powered device may allow the use of the battery pack with an invalid authentication, but only for a limited number of battery pack recharge cycles.

Multi-cell battery packs can be made safer with certain features that mitigate the consequences of cell failure. Parameters of a cell are monitored to determine when the cell should be disconnected from the pack in case of a fault. The battery is reconfigured to continue operating in a safer mode. An over-charging prevention system reduces the maximum voltage that remaining battery pack can be charged to, so that the cells do not overcharge. Additional circuitry allows the disconnected cell to be periodically reconnected to the battery pack to determine if its conditions have sufficiently improved. The cells also include components for self-powering these cell functions while it is disconnected from the rest of the circuit.
