ABSTRACT:
A battery separator for use in flooded cell and recombinant type lead acid batteries. The separator has a relatively thin backweb (between about 0.002 inch and about 0.008 inch). A plurality of submini-ribs extend from one or both planar faces of the backweb. The submini-ribs are substantially parallel to the longitudinal side edges of the backweb and are substantially evenly spaced across the width of the backweb. The submini-ribs are relatively short in height (between about 0.003 inch and about 0.009 inch above the adjacent planar surface of the backweb) and relatively closely spaced together (between about 0.025 inch and about 0.050 inch).
