Abstract: An anti-spill arrangement is disclosed for a liquid electrolyte battery. The device comprises a chamber configuration or arrangement for containing electrolyte associated with a battery cell, when a battery is tipped toward or onto any one of its sides. The chamber arrangement has an inlet in communication with an associated battery cell and an outlet in communication with a vent to atmosphere. The chamber arrangement is such that regardless to which side a battery having the device is tipped, electrolyte flows from the associated battery cell into the chamber arrangement to a level which blocks further electrolyte flow through the inlet. The chamber arrangement is such that the contained level of electrolyte remains spaced from the outlet of the arrangement. Thus, this type of device precludes flow of electrolyte out of the anti-spill device when the battery is tipped to any one of its sides.
