ABSTRACT:
A recombinant lead acid battery is provided having positive and negative plates coated with active material and separated by a compressible separator material containing an electrolyte. A casing provides structural support for the plates and encases the battery's components. The battery is preferably a recombinant lead acid battery with its plates being formed of lead foil sheets. The casing is reinforced and arranged to i) maintain a substantially evenly distributed compressive force on the separator material and ii) maintain a constant spacing between the plates. The battery is arranged to maintain a compressive force of at least eight psi on the plates which has been found to significantly reduce the incidence of premature capacity loss (PCL). By way of example, compressive forces in the range of 8-14 psi work well for conventional separator materials. In one embodiment, the casing includes a plurality of reinforcing support pins extending between upper and lower casing members through the plates and separator material for maintaining the evenly distributed pressure. Plates may be slacked one above another to provide a plurality of cells. A method of making the battery is also described.
