Terminal straps are positioned within a battery container via multiple formations formed integral to the battery container. The unique formations provide for positive location of the terminal straps relative to the battery container and the battery container lid simplifying the manufacturing process and improving product quality.

Method and apparatus for positioning a battery terminal strap

A cast strap for a lead-acid battery is made of a lead-based alloy consisting essentially of from about 2.5 to 3.5 wt. % antimony, about 0.01 to 0.5 wt. % arsenic, about 0.01 to 0.5 wt. % tin, about 0.008 to 0.1 wt. % selenium, and the balance lead. The content of at least one of arsenic, tin and selenium is within the following ranges: about 0.075 to 0.5 wt. % tin, about 0.1 to 0.5 wt. % arsenic, and 0.021 to 0.03 wt. % selenium. For lead-based alloys containing antimony, arsenic, tin and selenium, increased additions of antimony, arsenic, and selenium generally have a favorable effect on long term corrosion resistance of battery straps in a lead-acid battery environment, whereas tin has an unfavorable effect such that increased amounts of tin dramatically lower high temperature corrosion resistance. The unfavorable effects of tin on corrosion resistance are moderated by adjustment of the levels of the other three elements, particularly arsenic, which can provide a predictable level of increase in corrosion resistance for a given arsenic content. A family of alloys highly suitable for use as cast-on battery straps and intercell connectors has been developed based upon these relationships.
