Abstract
A process of preparing a continuous cast lead-based alloy strip for use in the manufacture of a battery grid of a lead-acid battery, the process comprising mechanically deforming, at a deformation temperature in a range of about 15 to about 150° C., a continuous cast lead-based alloy strip having a thickness of tthat is in a range that is from about 0.6 to about 2 mm to reduce the thickness of the strip to a thickness of tthat is in a range that is from about 0.4 to about 1.5 mm such that the reduction in thickness is in a range of about 10 to about 50%, wherein the lead-based alloy comprises lead and silver and is essentially free of calcium, and wherein the silver is at a concentration that is in a range of about 0.003 to about 0.015 weight percent.
