A method of encasing batteries where the battery electrodes are assembled with spacers maintaining the electrodes in a spaced relationship to define an electrolyte cavity. In practicing the method, the electrode assembly is immersed in a body of molten casing material whereby the casing material solidifies to form a web between the electrodes and define the electrolyte cavities. The supports for the assembly during immersion extend across the electrodes and are coated with casing material so that upon removal of the supports transverse tubular manifolds are defined. A single port to the manifold and the plurality of electrolyte cavities is also provided upon removal of the supports.
