Abstract
A unique method and apparatus for charging a battery enables the safe and efficient charging of a battery (102) which may be removed during charging. An electronic device (106) may not be adapted to be powered by the external power supply (114) without a detachable battery, or more importantly, the internal circuitry (200) may be damaged when the detachable battery is removed while the power supply is attached. Also, a battery may not be properly charged if a battery is replaced in the middle of a charging program for the battery. By periodically interrupting (306) the charging current, a device may turn itself off before circuitry or components are damaged if a battery is removed, and reset the charging program to correctly charge a battery if the battery is replaced.
