A lead-acid battery is disclosed. The lead-acid storage battery has a container with a cover, the container including one or more compartments. One or more cell elements are provided in the one or more compartments. The one or more cell elements include a positive plate, the positive plate having a positive grid and a positive electrochemically active material on the positive grid; a negative plate, the negative plate having a negative grid and a negative electrochemically active material on the negative grid, wherein the negative electrochemically active material comprises barium sulfate and an organic expander; and a separator between the positive plate and the negative plate. Electrolyte is provided within the container. One or more terminal posts extend from the cover and are electrically coupled to the one or more cell elements.
