Abstract
A lithium-ion battery (126) is normally charged using a constant current/constant voltage charge regime (206, 210), where the battery is charged to a preselected normal voltage level (210) whereupon the voltage is maintained at the limit while the charging current diminishes. The battery charge capacity can be selectively increased by charging the battery to an enhanced voltage level (212). The enhanced charging mode is selected by a user via a device user interface (112), or alternatively by a broadcast command (304) transmitted to the device.
