Abstract
Apparatus for charging a NiCd battery in a portable electronic apparatus, specifically a radio telephone. A charger includes a trickle charge circuit and fast charge circuit which can be selectively enabled by a switch under the control of a signal Vc generated by a voltage generator within the telephone. The charge mode may be selected automatically from within the telephone, e.g. depending on the charge state of the battery as detected by the charge state sensor. Additionally or alternatively the charge mode may be selected manually by depressing appropriate keys on the telephone. Preferably the charge mode is enabled by selecting an appropriate menu which is indicated visually on the display area of the telephone. This charging apparatus facilitates the adoption of a battery charging regime which optimizes battery life.
