Abstract
A method of assembling a bipolar lead-acid battery includes assembling the electrochemical components necessary to provide the necessary voltage and capacity, maintaining the electrochemical components under the desired compression and then sealing such electrochemical components as a unit utilizing various assembly components. The resulting bipolar battery in the preferred embodiment includes an electrolyte fill/vent box that seals the top of the electrochemical component unit and a vacuum box that seals the bottom surface.
