A lead-acid battery having a unique arrangement for making electrical connection to the battery. The arrangement includes L-shaped lugs molded into the upper surface of the casing. The lugs have cylindrical apertures extending horizontally therethrough for mating with the connector posts of the battery plates. Threaded pin terminals insert through a receptacle which is slidably mounted with a slot in a side wall of the battery. The pin terminals are threaded into nuts which are cast within the L-shaped lugs.
