Abstract

A charger includes a control circuit (308) for determining the charge rate and charge capacity of a battery (312). Control circuit (308) switches the rate at which battery (312) is being charged from a first charge rate such as a rapid charge rate (206) to a charge rate which is increasing in charge over time (208). Once battery (312) becomes fully charged, control circuit (308) then charges battery (312) at a third charge rate such as a trickle rate (214).
