Abstract

In a battery configuration including a casing (14) having a bottom, side and top surfaces, the top surface having a plurality of cell openings (22) therein, an improved flowpath is provided for liquid electrolyte when the battery is tilted onto any of its side surfaces. The flowpath includes a cover chamber for each cell opening defined by a substantially rectangular peripheral wall surrounding a cell opening; a cylindrical wall (24) surrounding and substantially concentric with the cell opening and located within the substantially rectangular wall, the cylindrical wall interrupted by a relatively small circumferential gap (26), and a wall (34) extending between the cylindrical wall and the adjacent side of the peripheral wall, the wall tangential to the cylindrical wall and adjacent the gap. A porous polytetrafluoroethylene disc (42) seated in the battery cover vent openings prevents spillage even if the battery casing is inverted.
