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: A multi-station machine for filling storage batteries has an unloading station, a loading station and a filling station. At the unloading station, a filled battery case is removed from a pivotally mounted cradle assembly including an acid container. At the loading station, adjacent the unloading station, the battery case is loaded in the cradle assembly in a vertical orientation and then tilted to and latched in an angular orientation. At the filling station, the battery case and acid container are further tilted to a horizontal orientation, the container is filled with acid and then returned to the tilted and latched orientation. When all of the cradle assemblies are filled with battery cases and acid container are filled with acid, the cradle assemblies, are spun at a speed sufficient to rotate the assemblies to a more tilted orientation to cause centrifugally induced flow of the acid into the battery case while simultaneously unlatching the cradle assemblies.
