Abstract
A method for making a plurality of lead-acid cells requiring a constant width, a height varying from a maximum to a minimum to accommodate plates of varying height and a cell depth to accommodate a minimum to a maximum number of plates is disclosed which utilizes blow molding to form a jar precursor which is cut to the height desired, and, in its preferred aspects, including use of a mold and insert sets which simplify tooling and change-over time, as well as a cover and jar design which simplifies the heat sealing of these components.
