Abstract: A plastic battery container for a recombinant sealed lead-acid battery having reduced end wall deflection, the end wall comprising a base portion from which extends a series of integrally molded ribs disposed at approximately +/−45° to the horizontal, substantially all intersection points of the ribs with the base portion having a rounded character to enhance processing characteristics.

Abstract: A removable battery handle and battery casing coupling structure wherein the handle is relatively rigid and includes a central portion, and two downwardly depending arms, the distal ends of the arms each including an attachment button which is supported on the inside surface of the distal end by a shaft, the button being received by a keyhole-shaped aperture in the battery casing end wall, which offers resistance as the shaft moves from the lower, larger portion to the upper, smaller portion of the aperture such that when the shaft is disposed in the upper, smaller portion, the handle is locked to the casing.
