ABSTRACT:
A leak proof horizontal-type venting system for an electric storage battery including an exhaust chamber adjacent an exhaust port, a reservoir chamber for collecting and trapping electrolyte exiting the battery when it is laid on its end or side, and an isolation chamber between the exhaust and reservoir chambers. The reservoir chamber has inner and outer compartments formed by inner and outer partitions which partition each have an opening therein which is not aligned with the opening in the other partition, and which lies in a plane laying above a venting aperture in the floor of the reservoir chamber when the battery is oriented in certain directions and in a plane laying beneath such aperture when the battery is oriented in other directions thereby creating a maze which traps electrolyte within the reservoir chamber when the battery is tilted and becomes air locked.
