Abstract
The present invention is an apparatus and method which allows a smaller size battery to be adapted for use in a device which uses larger size batteries, thus saving energy costs. The apparatus can be mass produced from recycled in-expensive materials and is far less costly to manufacture than existing battery conversion devices.
Claims19
An apparatus comprised of:
- a foam tubular member having an outer diameter greater than 26.2 mm adapted to receive and secure at least two batteries having diameters less than 14.5 mm, said foam tubular member adapted to receive a first conductive end cap having an inner surface, outer surface, and a protuberance affixed to said outer surface and a second conductive end cap having an inner surface, outer surface, and a protuberance affixed to said outer surface;
- wherein said first conductive end cap is attached to a first end of said foam tubular structure and said second conductive end cap is attached to a second end of said foam tubular member.
An apparatus comprised of:
- a lightweight foam tubular member having an outer diameter greater than 26.2 mm adapted to receive and secure at least two batteries having diameters less than 14.5 mm, said foam tubular member adapted to receive a conductive end cap having an inner surface, outer surface, and a protuberance affixed to said outer surface;
- wherein said conductive end cap is permanently attached to said foam tubular member so that said protuberance faces toward the center of said foam tubular member.
A method of manufacturing a battery conversion apparatus comprising the steps of:
- creating a foam tubular member with an outer diameter greater than 26.2 m from at least one modular unit, said foam tubular member having a first end and a second end;
- adapting said foam tubular member to receive and secure at least two batteries having diameters less than 14.5 mm;
- creating a first conductive end cap and a second conductive end cap, each of first conductive end cap and said second conductive end cap having a protuberance;
- and
- attaching said first conductive end cap to said first end of said foam tubular member so that said protuberance extends into said foam tubular member.
