Lead-acid cells and batteries and positive plates for such cells and batteries are provided. The positive plate comprises a grid supporting structure having a layer of active material pasted thereto, the grid supporting structure comprising a lead-based alloy consisting essentially of lead, from about 0.02% to about 0.06% calcium, from about 0.2% to about 3.0% tin, and from 0.01% to about 0.02% silver. A positive plate in accordance with the invention has excellent mechanical properties, is satisfactory for use in lead-acid cells and batteries, and imparts enhanced electrical performance to cells and batteries using such positive plates. |
