Abstract
Abstract A battery terminal comprises a thermally and electrically conductive bar. Means are provided to connect one end of the bar to an electrical cable and the other end of the bar to cells of the battery. The bar leads out through a battery casing and heat dissipating means fastened to the battery casing. The heat dissipating means are in good thermal contact with and electrically insulated from the lead out bar.
