  • Battery with vent cap assembly
    Patent number: 6461758
    Abstract: An improved vent cap system for use in an electrochemical battery is provided which includes a ring flange for forming a ring seal between the vent cap assembly and the fill tube. When the vent cap assembly is positioned in the battery housing, the ring flange and the fill tube deform to create a seal therebetween to provide a fluid tight seal.

  • High current low resistance double latching battery switch
    Publication number: 20020031700
    Abstract: A switch for controlling the supply of current from a battery cell in a cell cavity to a battery terminal in a battery casing is disclosed. The switch includes a mounting base, a first buss bar connected to the mounting base and connectable to the battery cell, a second buss bar connected to the mounting base and connectable to the battery terminal, and a relay having open and closed positions. The relay includes a third buss bar that places the first buss bar and the second buss bar in contact to provide current from the battery cell to the battery terminal when the relay is in the closed position. The relay is moved into a latched open position when a first winding of a coil of the relay is energized by electricity, and is moved back into a latched closed position when a second winding of the coil is energized.

  • Battery terminal bushing having frontal access to battery termination
    Patent number: 6258481
    Abstract: A battery is delineated comprising, in combination, a battery cover having a Cast on Strap (COS) post extending into an aperture located in a top surface of the battery cover; and a battery terminal bushing, integrally coupled to the battery cover, having a first portion fitting about and coupled to the COS post, and having a second portion extending away from the first portion approximately orthogonally. The second portion of the battery terminal bushing extends through the battery cover and is accessible via an aperture located on a side surface of the battery cover, thereby providing frontal access to battery termination.
