ABSTRACT:
A battery unit charger system is provided which includes a charger (110) for supplying charge current and a battery (120) having a memory (122) for storing battery-related information. The charger (110) includes a controller which exchanges the battery-related information with the memory (122) and in response thereto, controls overall operation of the charger (120). The battery (120) includes a common battery port (126) for selectively receiving charge current and for exchanging data with the charger (120). The controller cuts off the supply of charge current when data is being exchanged with the memory through the common port (126).
