Abstract
Disclosed are a method of manufacturing a lead (or lead alloy) plate lattice for a lead-acid battery, featured in that a melt of lead or a lead alloy is continuously extruded under temperatures lower by 10 to 100.degree. C. than the melting point of lead or the lead alloy, followed by subjecting the extrudate to cold rolling under temperatures lower by 50 to 230.degree. C. than the melting point of lead or the lead alloy with the total draft rate set at 10 to 90% and subsequently cooling and processing the cold rolled extrudate so as to manufacture a plate lattice, and a lead-acid battery comprising the particular lead (or a lead alloy) plate lattice.
