ABSTRACT:
A battery pack is selectively connectable to electrical equipment and to a battery charger. The electrical equipment or battery recharger decides whether the attached battery pack is a compatible device. If the attached battery pack is determined to be suitable, electrical power is transferred from the battery pack to the electrical equipment or from the battery recharger to the battery pack. To determine whether the battery pack is compatible, the electrical equipment or battery recharger receives an electrical signal, from the battery pack, containing battery information by which the type of battery pack can be distinguished.
