A (e.g., 12-volt) lead acid battery having prismatic and wound prismatic battery cells that are arranged relative to one another within a standard battery casing to avoid wasted space whereby to improve the overall volumetric efficiency of the battery relative to conventional batteries having thick grids or cylindrical cell configurations. According to a first preferred embodiment, each battery cell includes a plurality of cathode and anode electrode plates, wherein each plate is manufactured from an electrically-conductive flexible foil covered on opposite sides thereof by one of a positively or negatively charged material. According to a second preferred embodiment, each battery cell includes flexible, electrically-conductive cathode and anode electrodes that are prismatically wound in an oval (i.e., flat) configuration, such that the battery cell is longer along the major axis thereof than along the minor axis. The batteries of this invention are capable of increasing their stored energy capability and maximizing their power performance by avoiding unused or wasted volume within the battery casing so as to improve the stored energy capacity and cold-cranking power.
