Abstract: A leak resistant battery manifold vent for a battery. The battery manifold vent includes a vent housing having an interior volume, at least two cell vents, and at least one atmospheric vent. The interior volume comprises a labyrinth system, fluid collection chamber, and vent collar. The labyrinth system has at least two fluid passageways coupling the cell vents and the atmospheric vent. The passageways include more than one fluid baffle. A fluid baffle causes a constriction of the fluid passageway extends from only one of a top portion and a bottom portion of the vent housing. The passageway is coupled by a crossover vent providing fluid communication between the two passageways. A fluid collection chamber is fluidly coupled to the passageways. The chamber has at least two orthogonal dimensions which are larger than two corresponding dimensions of the passageway. A vent collar causes a constriction adjacent the cell vent.
