Abstract: The pole bolt protruding through the cover aperture is surrounded by a section of shrink tubing. Adhesive is provided between bolt and tubing. A cap is placed over the bolt resting on the upper edge of the aperture, and a cast body fills the space between cap and shrink tubing.

Abstract: A lead storage battery terminal is constructed of copper or aluminum sleeving, which may be clad with lead, and is sealed into the terminal aperture in the battery lid. The bottom of the sleeve is closed and permanently attached to the lead pole bridge.

Abstract: An electric storage battery is disclosed having a case to retain electrolyte up to a given preferred level, cover means for retaining the electrolyte within the case, said cover means having defined therein at least one bore, said bore comprising at least one constricted section, probe means for sensing the preferred level of the electrolyte, said probe means being disposed through the cover, and resin means for chemically sealing at least a portion of said probe means with said cover means. In addition to the above, the present application discloses an inter-relationship between the remainder of the probe and the bore which allows for the introduction of resin between the surfaces of the probe and bore to create an effective seal between the probe and battery cover. Finally, a unique configuration of probe and bore is disclosed which produces a strong electrolyte tight seal between the probe and battery cover.

Abstract: The terminal pin assembly for a battery including an elongated cylindrical pin having a first end for extension exterior of the battery and a second end for extension interior of the battery where the second end has a larger cross-sectional area than the first end. Header means are included forming one end of the battery and defining an opening through which the pin extends such that the opening has a diameter larger than the first end of the pin. Bracket means are mounted on the interior side of the surface of the header means and extend inward from the surface, with the bracket means having a diameter larger than the opening in the header means. Sealing means are provided and are mounted on the exterior end of the pin and have a diameter essentially equal to the bracket means, whereby the bracket means is forceably enclosed about the sealing means.

Abstract: The plates of each polarity of an alkaline battery are connected by a sheet metal connector which passes through a slot in the bottom of a well formed in the battery lid, and which is supported by means of a pair of ears projecting from the connector which rest on the lid. Each connector is secured against vertical movement by abutment of the ears against the upper surface of the lid and by abutment of a respective plate strap to which each connector is welded against the lower surface of the lid. Horizontal movement in one plane is prevented by the provision of a shoulder on the lid on each side of each ear, and in the other plane by abutment of the connector, or the ears, against the edge of the well or a further shoulder respectively. The slots are sealed by means of a sealant which fills the wells. Upstanding ribs are provided on the upper surface of the lid so as to increase the length of the leakage path between neighboring cells.
