ABSTRACT:
An air-vented battery cell containing liquid electrolyte is rendered leakproof against spillage during shipping and during usages when the cell is tilted from a vertical position in any direction to a horizontal position, as when used on a marine buoy, by providing the cell with a vent reservoir across the top thereof having a liquid connection with the cell at only one corner thereof and having a vent tube in the reservoir at the top part thereof, leading through one end wall diagonally to nearly an opposite corner portion thereof. In three tilt positions of this cell at 90.degree. intervals from a vertical to a horizontal position, a limited flow of electrolyte into the reservoir is well below the inner open end of the vent tube, and in the fourth such tilt position the electrolyte in the reservoir enters the vent tube through only a small length, typically 10-20% thereof, with the result that the cell is protected against any leakage from shaking thereof while tilted and is provided further with a reserve against leakage through the vent tube if an increase in gas pressure occurs within the cell while it is so tilted.
