Abstract
In a system for charging a rechargeable battery, an electrical device powered by a rechargeable battery has a body that fits into a receiving cavity in a charging base for recharging the battery. The electrical device is provided with a retractable charging terminal mechanism that causes a terminal leading to the rechargeable battery to protrude from the body of the electrical device to make contact with a recessed electrical contact in the base when the electrical device is seated in the base cavity and retracted back into the body of the electrical device when it is removed from the base cavity.
