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.

Lead-acid cells and batteries

A sealed lead-acid cell or battery includes positive plates made from an alloy consisting essentially of lead, from about 0.025% to about 0.06% calcium, from about 0.3% to about 0.9% tin, and from about 0.015% to about 0.045% silver.

Sealed lead-acid cells and batteries

A lead-acid storage battery for starting, lighting and ignition applications is disclosed which minimizes convection-induced, heat transfer from the vehicle underhood environment surrounding the battery to the battery itself and comprises an injection-molded, integral plastic container, or a two-piece container, having a multi-wall configuration in which an inner container includes the cell elements of the battery and at least one outer container spaced from the inner container provides at least one fluid compartment for allowing fluid flow through the fluid compartment to achieve the desired thermal regulation, the fluid flow path being created by a series of spaced fluid baffles.

A continuous method for making starting, lighting and ignition lead-acid battery positive plates and the resulting battery is disclosed which utilizes a direct cast alloy strip wherein the alloy consists essentially of lead, from about 0.02 to 0.05% calcium, from about 0.3 to about 0.5% tin, and from about 0.02 to 0.05% silver, the percentages being based upon the weight of the alloy strip, as well as related alloys utilizing calcium and strontium or strontium in place of calcium.
