Abstract:
A lead-acid battery grid made from a lead-based alloy containing, in addition to lead, tin at a concentration that is at least about 0.500%, silver at a concentration that is greater than 0.006%, and bismuth at a concentration that is at least about 0.005%, and, if calcium is present in the lead-based alloy, the calcium is at concentration that is no greater than about 0.010%.
