Abstract
A battery charger (12) and battery pack (14) are each provided with a wireless communications device, (24) and (28) respectively, to communicate over a wireless channel (32). The battery charger (12) receives charging information from a memory (30) housed in the battery pack (14), and commences a recharge process in accordance with the received information when the battery pack (14) is electrically coupled to the charger (12). The charger may update the information contained in the battery'"'"'s memory (30) during the recharge process.
