Adaptive battery conditioning employs battery chemistry determination to establish how, when and whether to condition a battery. As a result, the conditioning is optimized for the determined battery chemistry. Further, conditioning of a battery that is not conditionable, such as a nonrechargeable battery, is prevented. A device determines battery chemistry in situ from a measurement of a characteristic of an installed battery, and conditions the installed battery in situ. The device can be a battery-powered consumer electronic device or a battery charging and conditioning system that is independent of an electronic device that uses the conditioned battery. A method of adaptive battery conditioning includes determining a chemistry of a battery from a measurement of a battery characteristic, and conditioning the battery according to the determined battery chemistry.

Adaptive battery conditioning employing battery chemistry determination

An apparatus that prevents standard dry cell batteries from being installed in a battery compartment in a reverse polarity arrangement. The battery compartment operationally houses at least one dry cell battery having a cylindrical casing with positive and negative terminal surfaces on opposing ends thereof. The positive terminal surface has a button protruding from the casing. In this aspect of the invention, the battery compartment is configured with positive and negative device contacts disposed in opposing ends of each battery cradle of the battery compartment to contact positive and negative terminals, respectively, of a dry cell battery installed therein. The battery compartment also comprises a reverse polarity exclusion device disposed in each battery cradle. The device is interposed between the positive device contact and a dry cell battery installed in the battery cradle. The device permits the positive terminal button to abut the positive device contact while preventing the negative terminal of the installed battery from abutting the positive device contact.
