Abstract
Positive grids for lead-acid batteries for SLI, industrial battery, and electric vehicle batteries are disclosed in which the positive active material paste pellet openings have a reduced area and the number per square inch of the grid area are increased, the individual areas and the number of paste pellets varying with the intended application, and the preferred embodiments including reduced distances from the center of the paste pellet to the adjacent grid wires, as well as an optimized amount of positive active material per area of the grid wire surface area so as to allow enhanced electrical performance, if desired, or substantial savings in grid weight while achieving electrical performance commensurate with conventional lead-acid cells and batteries.
