Abstract

A flooded lead-acid battery includes a pasting substrate embedded into an active material of at least one surface of either the positive plates or the negative plates of each respective plurality, wherein the pasting substrate has an initial thickness. The pasting substrate thickness has a compressed thickness within the container that is at least 10 to 20 % less than the initial thickness. The pasting substrate may comprise a blend of fibers. The pasting substrate may be a non-woven substrate comprising glass fibers. It has a weight of 23 g/m2 to 31 g/m2. The glass fibers comprised are more than 50 wt.-%.
