A method of making battery plates of pure lead battery grids for lead-acid battery manufacture is presented. The method has been shown to resolve issues that have long-persisted in the battery manufacture industry involving the use of pure lead material for battery grids. According to an implementation, several processes are performed in succession in order to make pure lead battery grids feasible in commercial and mass production, among them: a continuous casting process to produce battery grids of pure lead material, a compression rolling process of the cast pure lead battery grids, and a battery paste application process to the cast and rolled pure lead battery grids. The pure lead material of the continuous strip of pure lead battery grids can consist of lead (Pb) material in an amount that ranges approximately between 99.85 percent (%) to 99.999% of the overall constituent elements of the pure lead material.
