ENCLOSED LEAD STORAGE BATTERY

摘要

PURPOSE:To prevent leakage of liquid without excessively limiting the volume of electrolyte nor requiring independent foam barrier board by providing a double tube section coaxially with an exhaust port below the exhaust port while making notches at the unmatched positions of double tube section. CONSTITUTION:Double structural tube sections 3, 4 are provided coaxially below an exhaust port 2 while notches 3a, 4a are made respectively in the tube sections 3 and 4 at the unmatched positions. When employing such double tube structure below the exhaust hole, an enclosed lead storage battery which will never leak the liquid at any position can be obtained.
