ABSTRACT:
Many post seals for lead-acid batteries make use of compression seals. These seals, when used on the positive post, are often subject to abnormal anodic corrosion. The invention is a lead-acid battery in which the positive post is made of a tin-lead alloy (generally from 0.1 to 1.2 weight percent tin). The use of such an alloy at the positive post greatly reduces the rate of anodic corrosion.
