Abstract: GIH-01 A HOLE IN THE TOP OF A BATTERY IS COVERED BY A GAS PERVIOUS, LIQUID IMPERIOUS MEMBER SECURED TO THE TOP IN A MANNER WHICH PROVIDES A LIQUID-TIGHT CLOSURE AROUND THE HOLE. THE GAS PERVIOUS, LIQUID IMPERIOUS MEMBER MAY BE EXTENDED TO AND AROUND THE EDGE OF THE TOP WHERE IT IS CRIMPED BY THE CONTAINER AND WHERE IT FUNCTIONS AS A GROMMET TO PROVIDE A LIQUID TIGHT- CLOSURE AROUND THE OERIMETER OF THE TOP. THE GAS PERVIOUS, LIQUID IMPERIOUS MEMBER MAY BE CRIMPED BETWEEN THE TOP AND AN ELECTRICCALLY CONDUCTIVE CONTACT MEMBER WHICH IS SECURED TO THE TOP. CONSTRUCTIONS ARE ILLUSTRATED IN WHICH THE GAS PERVIOUS, LIQUID IMPERIOUS MEMBER IS ELECTRICALLY NONCONDUCTIVE, WHILE OTHER CONSTRUCTIONS ARE SHOWN IN WHICH THE MEMBER IS CONDUCTIVE.
