A method and apparatus for charging a rechargeable battery in which a constant current (Icc) is first applied until the rated voltage of the battery is reached, followed by a period (Rc) during which a reduced current (Ir) is applied to the battery. The reduced current results in lowering the amount of unwanted heat being dissipated in the charge-current transistor connected to the battery. Finally, a constant voltage (Vcv) is applied to the battery to finish the charging cycle. Reducing the heat dissipation enables the use of smaller less expensive charge-current switch transistors, which for example, are advantageous in applications such as mobile communication devices or other portable electronics assemblies. |
