Abstract
A lead-acid battery includes a compartmented case and a polarity of electrochemically lead-acid cells serially connected via respective positive and negative terminals. Each cell includes planar positive and negative plates and resides in one compartment of the case. The battery further includes an electrochemically inactive cell serially connected with the electrochemically active cells and being intermediately disposed respecting the electrochemically active cells. Plates of the inactive cell preferably have connecting lugs extending therefrom which align with corresponding connecting lugs of the positive and negative plates of the active cells. Rigid homogeneous foam separates the inactive cell plates from one another and fills the inactive cell compartment thereby providing support for the inactive cell plates.
