Battery terminal system

Abstract

A lead terminal post extending upward through the top of an insulator wall of a battery includes a plurality of flat vertical sides fused continuously from its top to below the top of the insulator wall, to a harder, metallic, cap having a plurality of flat vertical sides. The metallic cap is covered with a plastic cap that extends below the metallic cap, below the top of the insulator wall, and is sealed to the insulator wall. A terminal bar having parallel walls extends from a flat wall of the cap, through the plastic cap, normal to the flat wall, and contains a removably mounted connector having a leaf spring connection with the terminal bar and an element within the connector adjacent to and connected to the leaf spring, that prevents horizontal rotation of the connector on the bar. A plastic overseal on the connector makes a seal with the plastic cap when the connector is fully mounted on the terminal bar. The terminal bar may be a dedicated electrically negative terminal for carrying starter current, and may have a connector fastener.
