This invention includes an adaptor that facilitates reconditioning and charging
of non-smart batteries in smart chargers. The adaptor includes a mechanical and
electrical interface to the host-side of a non-smart battery, thereby bypassing
any protection diode. The adaptor further includes at least one memory device that
identifies the adaptor to a smart charger as an adaptor. Upon insertion, the smart
charger reads the memory device in the adaptor begins the reconditioning process.
The reconditioning process includes discharging the non-smart battery to a predetermined
voltage stored memory device. The smart charger then waits a predefined period
and begins charging the non-smart battery, preferably at a constant current. Charging
is terminated at a V-peak inflection. Upon completion of charging, the smart charger
may trickle charge for a time, and then indicates charge is completed.
