ABSTRACT:
A rechargeable power pack is shaped and dimensioned to be inserted in the battery compartment of an electrical device. The top of the power pack is exactly symmetrical with the battery compartment cover which it replaces. The power pack houses rechargeable power cells, and has a peripheral wall spaced apart from the sides of the battery compartment mounting the battery contact terminals. Flexible prongs project from the peripheral walls to provide a wiping contact with either a spiral spring negative terminal or stationary positive terminal of the compartment. A top mounted connector allows recharging of the power pack either during or after the operation of the electrical device.
