Battery paste additive and method for producing battery plates

Abstract

A battery paste additive, and process for making the same comprising micronized seed crystals of tetra basic lead sulfate, is added to battery paste and results in accelerated curing time and other improvements in battery performance. The battery paste additive may be used to produce positive or negative battery plates and may be use with conventional mixing, pasting and curing processes and equipment.
