Obsolescence is a thing of the past relative to the Industrial Motive Power Traction Battery industry….that is, with the exception of the quarter-turn bayonet vent cap which has been in use and unchanged for over half a century.

Hand wrapped and vulcanized hard rubber jars gave way to the rotationally molded polyethylene jars which lacked dimensional stability – these in turn were replaced by the injection molded polypropylene jar. The compression molded hard rubber covers, both industrial and SLI, are a thing of the past having been replaced by the high density polypropylene injection molded cover. Insertable element supports (Bridge-rests) are now replaced by the self-leveling concept molded as an option and integral part of the industrial battery jar. Separators, grid alloys, lead oxides, expanders and tray designs as well as battery containers have all seen improvements over the years……but not the industry standard quarter turn bayonet vent cap relative to O.E.M. production.

The original ¼ turn vent caps were injection molded by Stokes Molded Products in Paterson, New Jersey. At the time, the design was proprietary to Exide which had split their operations into two separate divisions – automotive and industrial. Then in July , 1930 Exide purchased Gould Storage Battery Corporation expanding it’s line into high-capacity industrial motive power traction batteries. In September 2000 Exide acquired GNB. This acquisition allowed Exide to reenter the North American industrial battery market.

Today, Exide Technologies is one of the world’s leading manufacturer of industrial motive power traction batteries and still use the original designed ¼ turn bayonet vent cap as does the Golf Cart, Floor Scrubber and Industrial Battery manufacturers.
