Abstract

A battery charger (230) is provided for charging a battery (210) at high temperatures. The charger (230) includes a thermistor (236) for monitoring the ambient temperature and a rapid charger (232) for providing the charge current to the battery. When the ambient temperature exceeds a high threshold temperature and when the battery (210) needs to be charged at this temperature, the battery charger (230) rapid charges the battery until the battery temperature reaches a cut-off temperature. The cut-off temperature is a temperature having a fixed level above the ambient temperature.
