Abstract: A thin film or coating containing an oxide of silicon or aluminum or both is deposited over lead or lead alloy battery components that will be in contact with the acid electrolyte greatly reducing the corrosion of the lead components during battery use. In one embodiment, the coating of film may be applied using a colloid of silica or alumina in a binder such as room temperature vulcanized rubber. In another embodiment, the coating of film is deposited by a direct silane polymerization of an oxidized lead surface by silicic acid forming the film. The substantial reduction of component corrosion eliminates leaking around the terminals and thereby increases the service life of the lead acid battery.

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.
