Abstract
A method and apparatus for preventing a rechargeable battery in a self-charging electronic device from being charged while the electronic device is resting in a charging cradle comprising placing an isolation element between a first set of electrical contacts on a charging cradle and a second set of electrical connections on a self-charging device. The isolation element preferably comprises a material with a sufficiently high dielectric constant to prevent current from flowing from the first set of electrical contacts to the second set of electrical contacts. Therefore, the rechargeable battery is not subjected to a constant recharging current flow which can limit the total recharge capacity of the battery.
