A circuit (130) for preventing corruption of battery-specific data transferred from a battery-specific data element (108) to a battery charger (110) when a battery (100) is electrically coupled to both the battery charger (110) and to a load (120), includes a charger connection sensor (116) and an interrupter circuit (134). The charger connection sensor (116) is capable of sensing when the battery (100) is connected to the battery charger (110). The interrupter circuit (134) is responsive to the charger connection sensor (116). The interruptor circuit (134) electrically couples the battery-specific data element (108) to a load side battery-specific data node (124) when the charger connection sensor (116) indicates that the battery is not connected to the battery charger (110), and electrically uncouples the battery-specific data element (108) to the battery-specific data node (124) accessible by the load (120), when the charger connection sensor (116) indicates that the battery (100) is connected to the battery charger (110).
