ABSTRACT:
A battery charger charges a battery in a portable chargeable electronic device, such as a cellular phone, with a long-term-constant current, even while the device is used. The charging current is controlled by circuitry in the portable device, avoiding the need for control circuitry in the battery charger or battery. A battery-charger connector that corresponds to the type of battery in the portable device is keyed to fit only a charger that matches the type of battery, thus assuring proper charging of the battery. Alternatively, a simple contact connects the battery charger to the battery. A belt clip covers the battery-charger connector when the battery charger is disconnected to prevent short-circuiting the battery.
