1. A method for dynamically charging a battery having a voltage, comprising the steps of:
- determining a dynamic baseline voltage for the battery after the battery has been charged for a predetermined period of time;
establishing a voltage range based on the dynamic baseline voltage;
charging the battery at a predetermined charge rate;
monitoring the voltage of the battery; and
adjusting the rate at which the battery is being charged if the voltage of the battery falls outside of the voltage range.

Abstract
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.
