Abstract
A circuit for preventing corruption of battery-specific data transferred from a battery-specific data element to a battery charger when a battery is electrically coupled to both the battery charger and to a load includes a charger connection sensor and an interrupter circuit. The charger connection sensor is capable of sensing when the battery is connected to the battery charger. The interrupter circuit is responsive to the charger connection sensor. The interrupter circuit electrically couples the battery-specific data element to a load side battery-specific data node when the charger connection sensor indicates that the battery is not connected to the battery charger and electrically uncouples the battery-specific data element to the battery-specific data node accessible by the load when the charger connection sensor indicates that the battery is connected to the battery charger.
