ABSTRACT:
A convertible battery handle is provided in which an extended end cap contains a drive spring electrically insulated from the battery circuits to physically hold the rechargeable battery pack or non-rechargeable battery cells in proper position and a coaxial helical spring electrically connected into the battery circuit. The helical spring has a length insufficient to make electrical contact when the handle is utilized with a rechargeable battery pack, but when a pair of non-rechargeable dry cells are positioned in the handle the electrical circuit is completed through the spring. A safety diode is placed in the series with the electrical circuit for the non-rechargeable cells to prevent inadvertent charging of the cells.
