Abstract: This present invention provides a method for creating a gas restrictive interface between a battery case partition formed in a battery case and a battery plate strap, which extends through the partition in a series connection and is part of a battery cell block, which is received within the battery case. The battery case partition includes a notch having a sealing material disposed thereon so that when a heated battery plate strap is positioned within and across the notch, a first gas restrictive interface results between the battery plate strap and the case partition. A battery case lid having a partition tab extending therefrom forms a second gas restrictive interface with top surface if the battery plate strap by being received and secured within the notch of the battery case partition. The bottom edge of the partition tab includes the sealing material to complete the gas restrictive interface.

Abstract: An electrical storage battery is supported on a tray which is secured to a frame member. The tray and battery have interlocking notches which maintain the battery relative to the tray. A heat shield is positioned to cover the battery and secured to the tray. The securement structure includes a slot in the tray, retaining tab on the heat shield and a retaining clip. The retaining tab is inserted in the slot in the tray. The retaining clip passes through a slot on the heat shield and engages the slot in the tray to restrict movement of the retaining tab. The periphery of the heat shield is supported on three sides in grooves on the tray.
