More Information
Summary:A lead acid cell including a positive plate or grid has been discovered involving Pb/Ca/Sn/Ag alloy. An interaction between tin and silver which lea ds to optimum tin and silver levels which are substantially different than thos e indicated in the prior art. The described optimum tin and silver levels results in a positive alloy with superior mechanical properties and improved corrosion resistance which leads to superior battery life in present day SLI applications. In a preferred manner, the alloy includes lead, tin in the ran ge of about 0.8 % - 1.1 %, silver in the range greater than 0 to about 0.017 % with a tin to calcium ratio greater than about 12:1.
