Abstract
A method for charging a rechargeable battery pack includes identifying battery capacity, determining sampling interval length according to the battery capacity, and implementing the determined sampling interval length. Also disclosed herein is a method for charging batteries comprising identifying battery capacity, determining current-on period length in duty cycle according to the battery capacity, and implementing the determined current-on period length. Further, disclosed herein is a battery charging apparatus comprising a charger for charging first and second batteries, where the first battery comprises a microprocessor. The charger further comprises at least one terminal for receiving a battery identification signal, so that the charger can distinguish between the first and second batteries. Also disclosed herein is a battery/charger combination comprising a battery comprising first, second and third terminals, at least one cell disposed between the first and second terminals and a microprocessor disposed within the battery between the first and third terminals, a charger connected to the battery via the first, second and third terminals, wherein the microprocessor controls charging of the battery by sending instructions to the charger.
