ABSTRACT:
A side terminal battery includes a terminal having a plug formed of relatively deformable lead disposed within an aperture formed in the battery casing, and a one-piece battery terminal insert embedded within the lead so as to be accessible from the exterior of the battery. An interior, closed-ended cavity, opening through the exposed end of the insert, is formed within the insert and includes interior threads for engaging a threaded battery connector fastener. The interior threads terminate before reaching the closed end of the cavity such that a true indication of battery connector fastener tightness is provided. The closed end wall of the insert forms a barrier between the end of the fastener and the interior of the battery casing, and a plurality of serrations on the outer surface of the insert permit the insert to rotate within the lead plug when a torque in excess of a predetermined maximum is applied to the insert. Thus, multi-level protection against battery damage is provided in the event a fastener of excessive length is utilized, or in the event the fastener is over-tightened within the battery terminal.
