A charger (302) determines the voltage baseline of a battery (306) and establishes a voltage range based on the voltage baseline of battery (306). Once the rapid charge rate has terminated and the trickle charge rate commenced, charger (302) monitors the voltage of the battery in order to make sure the battery is not being depleted. If the battery voltage is above the established range, the trickle charge rate is decreased, and if the battery voltage is below the voltage range, the trickle charge rate is increased.
