Method for making battery plates
A method of making a plurality of battery plates includes forming a strip including a plurality of battery grids. Each battery grid includes a grid network bordered by a frame element and includes a plurality of spaced apart grid wire elements. Each grid wire element has opposed ends joined to one of a plurality of nodes to define a plurality of open spaces in the grid network. The method also includes deforming at least a portion of a plurality of the grid wire elements such that the deformed grid wire elements have a first transverse cross-section at a point intermediate their opposed ends that differs from a second transverse cross-section taken at at least one of their opposed ends. The method also includes applying a lead alloy coating to the strip, applying battery paste to the strip, and cutting the strip to form a plurality of battery plates.
