SEALED LEAD-ACID BATTERY SEPARATOR

摘要

A separator for a valve-regulated lead acid battery consists mainly of fine glass fibers. The separator includes inorganic powder in an amount of 5 to 30 % by weight and natural pulp in an amount of 3 to 20 % by weight, and has a density of not less than 0.165g/cm<3>. The separator sufficiently suppresses the occurrence of electrical short circuits between the positive and negative electrode plates.
