A lead-acid cell or battery includes positive plates made from a lead-based alloy containing calcium, tin, and silver in amounts selected based upon the type of application and the plate fabrication method utilized, starting, lighting and ignition battery grids being directly cast and having calcium present in an amount of 0.03% to 0.050%, tin in an amount of 0.65% to 1.25%, and silver in an amount of from 0.018% to 0.030%, and the grids used in sealed, lead-acid cells comprising, when made by gravity casting, from about 0.035% to 0.055% calcium, 0.95% to 1.45% tin, and 0.018% to 0.030% silver, and, when made by continuous strip casting, calcium in the range of from 0.030% to 0.050%, tin in the range of from 0.95% to 1.25%, and silver in the range of from 0.017% to 0.030%, all of the alloy percentages being based upon the total weight of the grid.
