Michael R. Romeo, Jason P. Miller

Abstract

A method of making metal battery grids for lead-acid battery manufacture, as well as a metal battery grid manufacture assembly for lead-acid batteries, are set forth. A cleaning operation is performed to a continuous strip of metal battery grids that is continuously produced. The cleaning operation involves emittance of one or more laser beams via one or more laser assemblies to one or more exterior surfaces of the continuous strip of metal battery grids. Residual lubricants, oils, corrosion, and/or other additives or unwanted contaminants residing at the exterior surface(s) can be partially or wholly removed via the emittance of the laser beam(s). Enhanced surface adherence of a subsequently-applied battery paste material at the exterior surface(s) can result.
