Abstract: An improved manifold vented battery cover is disclosed. The disclosed battery cover has an improved manifold construction which is defined by the assembly of mated inner and outer members. In addition, the disclosed cover includes an external terminal post having a repositioning portion encapsulated within the mated inner outer members.

Abstract: A basket apparatus for clamping a plurality of plate stacks sufficient to form one multi-celled, lead acid storage battery during the casting of the lug commoning straps in each stack is provided. As configured it comprises a frame defining a plurality of internal cavities each configured to hold one of said stacks and a set of individually biased movable clamping plates, one in each of said cavities, each adapted to hold the stack firmly in position during the casting operation. The individual biasing permits firm gripping regardless of any variability in plate or stack thickness.

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.

Abstract: A novel mold having a plurality of channels for casting battery straps and posts on groups of battery positive and negative plates, the mold being equipped with a projection on at least one end of each of the channels, the projections extending into the channels of the mold toward the opposite end of the channel. The lengths of the mold channels are slightly less than the lengths of rows of positive or negative lugs so that the elements of the battery group are gently compressed or squeezed together. The end walls of the mold channels extend beyond the main mold body, a portion of the extended walls being beveled in a direction away from the mold channels.

Abstract: A maintenance free battery having explosion resistant characteristics for multi-celled battery containers. A battery cover has a main body with an elongate recess therein extending across its length. Within the first recess there are a plurality of vent well openings extending into the cells of the battery, and a plurality of vent plugs filling each opening which provide for the escape of gas and retard the escape of electrolyte. A recess plate fits snugly within the recess, the plate attaching to each of the vent plugs. Provisions are made to insure that the ends of the plate seal off the ends of the recess to prevent the leakage of gas between the plate ends and recess end walls.
