ABSTRACT:
A separator for a valve regulated lead acid battery is composed mainly of fine glass fibers and also contains inorganic powder, beaten natural pulp, and heat-weldable organic fibers. The heat-weldable organic fibers have a fineness of 1.5 d (deniers) or less and a fiber length of 1 mm or more, and the amount of the heat-weldable organic fibers is from 3% to 15% by weight. A valve regulated lead acid battery employs the separator.
