ABSTRACT:
A battery separator for use in deep cycle traction batteries, such as golf cart batteries. The separator is formed of a microporous, mainly polymeric layer, preferably in the form of a synthetic paper; a glass mat layer adjacent one surface of the microporous layer; and a coating on one or both sides of the mircoporous layer/glass mat combination. The coating is preferably formed of natural rubber which positively affects top-of-charge behavior and reduces the possibility of antimony poisoning, thus providing for longer and improved battery performance and life.
