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.
