ABSTRACT:
A vent cap for a storage battery, which vent cap includes a base portion and a cover portion which are retained to each other to provide a gas collecting enclosure. The base portion comprises a tray and peripherally extending walls, and is divided into a plurality of cavities by at least one transversely extending rib, which cavities include a first segment having an assembly which communicates with one of the cells of the battery and a second segment which is substantially enclosed to form a holding area and which is separated from the first segment by a plurality of baffles having an aperture which permits limited communication between the first and second segments. The cover portion comprises a substantially planar surface, having a plurality of cup shaped members depending therefrom and which cooperate with the assembly which communicates with the battery cell, and a plurality of slots positioned along an edge of the cover portion opposite the cup shaped members and capable of venting a gas from the second segment to the atmosphere.
