ABSTRACT:
A battery positive grid is continuously cast of lead and thereafter cold worked to reduce its cross sectional thickness to change the microstructure of the lead and provide enhanced corrosion resistance and other properties needed for positive grids. The as cast thickness is reduced by not more than ½ or 2 to 1, to produce a positive grid with a lead weight of 0.5 to 2.1 grams per square inch of the area of the plan of the cold worked grid which improves the life of a battery in which it is used. A battery negative grid is continuously cast of lead and thereafter cold worked to reduce its cross sectional thickness 1.2:1 to less then 1.5:1 to increase the ultimate tensile strength needed for a lighter negative grid with a lead weight of 0.3 to 0.9 of a gram per square inch of the area of its plan.
