Abstract
A rechargeable power cell having no voltage across its positive and negative power terminals unless the power cell is inserted into a device configured to accept the power cell is described. The power cell includes a battery management processor and battery insertion detection circuitry that cooperate to determine when the power cell is inserted into the device and then drive an electronic switch to provide for conduction of current from the power cell to the positive terminal of the cell.
