Abstract
A battery housing includes a contact cage forming a longitudinal cylindrical enclosure having a lateral opening. A leaf spring is included having first and second compressible ends, in which the first end is received by the contact cage through the lateral opening. A longitudinal insulating cup is also included having opposing cylindrical openings, in which the second compressible end of the leaf spring is received by the insulating cup through one of the cylindrical openings. The leaf spring forms a positive terminal in the battery housing and is held in position by the contact cage and the insulating cup.
