The explosion attenuating vent cap for storage batteries according to the present invention features an electrolyte drain and baffle design adapted for maximizing return to the battery of any liquid which may enter the vent from vibration, tilting, overheating, overcharge and the like. The vent barrel(s) include a step to assist in closure of the fill openings, and baffles within the vent prevent accumulation of electrolyte within the cap. The arrangement of the entrance to the gas escape passage (leading through an explosion attenuation device such as a disc of microporous polymer) is located on the center lines of the barrel and at the highest possible location within the vent to minimize the intrusion of electrolyte into the attenuation material. This location of the entrance prevents accumulation of electrolyte at that location. Preferably, the vent cap is of the ganged variety, i.e. useful for simultaneously capping three or more fill openings of the battery.

A vent cap for a battery of the type which includes a battery cover having electrolyte fill holes and electrolyte which may, during use, spew, spill, evolve or be pumped from the fill holes, the cap comprising: a chamber having a floor and plural barrels arranged linearly and extending from the floor and arranged to be inserted into the fill holes, the floor having a generally planar portion from which the barrels extend and an inclined portion arranged to facilitate drainage of any electrolyte entering the chamber to the planar portion; and the chamber including a flame arrestor having an entrance for gases which may enter the chamber through the barrels and an exhaust port, the entrance being located generally above a line extending through the centerline of the barrel openings.
