Abstract
A unique alloy comprising lead with small additions of zinc and tin is used to make grids for lead acid cells. The alloy as produced is softer than is desirable. It is hardened by mechanical working. When properly worked, it has a strength and stiffness approaching that of other low alloy lead materials currently in use as storage battery grids.
