Rechargeable cell holder
Abstract
Abstract An improved rechargeable cell is provided comprising an inner cell having a metallic casing with positive and negative electrodes and an electrolyte within the metal casing. An external non-metallic cylindrical case surrounds the metal casing. The non-metallic case has external dimensions, i.e. diameter and length which conform to conventional predetermined cell sizes such as C size and D size cells. The non-metallic case is provided with internal means to center the inner cell therein. An electrode connector coaxially positioned on the internal cell protrudes through a centrally formed aperture on one end wall of the non-metallic case. An enlarged second electrode connector which is attached to the opposite end of the internal cell has an exterior diameter substantially equal to the internal diameter of the non-metallic casing. These elements cooperate to position the internal cell within the non-metallic casing.
