Abstract: A battery pack is provided with an improved charger interface through the use a contact carrier assembly. The non-conductive contact carrier aligns and retains a plurality of charger contacts. The carrier aligns a first portion of each charger contact along a back surface of the battery pack housing and further facilitates alignment of another portion of each charger contact within bottom apertures of the housing thereby allowing each contact to extend across perpendicular back and bottom surfaces of the housing with improved ruggedness. Improved sealing is also provided by sealing the back of the carrier.

Abstract: A method and apparatus for controlling access to one or more memories in a rechargeable battery includes a switching circuit that connects the memory to a device data contact, and disconnects the memory from a charger data contact, when the rechargeable battery is connected only to a device powered by a battery. The switching circuit, however, connects the memory to the charger data contact and disconnects it from the device data contact. In some embodiments a second memory that contains a subset of the data in the first memory is connected to the device data contact when the first memory is connected to the charger data contact.
