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.
