A lead acid battery grid made from a lead based alloy containing calcium, tin, and silver having the following composition: calcium above 0.06 and below 0.082 %, tin above 1.0 % and below 1.2 %, silver between 0.005 and 0.020 %, and optionally containing up to 0.025 % aluminum. To enhance corrosion resistance and reduce grid growth, the grid optimally may contain 0.005 to 0.05 % copper as an alloying element complementary to and as a replacement for part of the silver, provided the silver content does not fall below 0.005 % and no more than a trace of aluminum is present. |
