A hybrid lead acid electric storage battery uses conventional lead-acid secondary battery chemistry. The battery is a sealed battery or an unsealed battery. The battery has a set of positive battery grids (plates) having cores of thin titanium expanded metal with a thickness, if flattened, preferably in the range 0.2 mm to 0.7 mm and most preferably 0.3 mm to 0.4 mm. The grid cores are of a titanium alloy containing a platinum group metal. The cores are coated with hot dip lead and are not lead electroplated. The negative plates are carbon based assemblies. Each such assembly has a metal core, preferably a sheet of expanded copper, a corrosion shield sealing the metal core, and an outer layer primarily of activated carbon covering the shield.
