Abstract
Abstract A spring contact is compressed against and electrically connected to a terminal of a dry cell battery, and the spring-like compressive force between the contact and the terminal is maintained by an adhesive. The spring contact and adhesive may be used with both single cell and multicell batteries. The spring may be situated between two cells of a multicell battery, with the adhesive adhering the two cells together and maintaining the spring-like compressive force between the contact and the terminals of the adjacent two cells. The terminal which is electrically connected with the spring contact may be a thin foil of metal, and the inner surface of the foil may serve as the negative electrode of a cell; the foil may be a metal selected from the group consisting of a zinc, magnesium, lead, aluminum and alloys thereof. The spring contact may have a burr where it electrically connects with the terminal. Where used between adjacent cells, the spring contact may be soldered or welded to the terminal of one of the cells. The spring contact may be compressed against and electrically connected to the outer terminal of an end cell in a multicell battery. A variety of adhesives, including hot melts and pressure sensitive adhesives, may be used.
