Claim 18:
19. A lead-acid storage battery comprising:
a container with a cover, the container including one or more compartments;
one or more cell elements in the one or more compartments, the one or more cell elements comprising:
a positive electrode, the positive electrode having a positive substrate and a positive electrochemically active material on the positive substrate;
a negative electrode, the negative electrode having a negative substrate and a negative active mass on the negative substrate, with the negative active mass having a composition with a normalized CO2 savings of greater than 2 g CO2/km, the composition comprises a leady oxide, at least one of a natural organic expander material and a synthetic organic expander material, a very fine particle barium sulfate, wherein the very fine particle comprises a range of from less than 0.1 μm to approximately 1 μm, and a first conductive carbon being activated carbon and a second conductive carbon being graphite and each of the first conductive carbon and the second conductive carbon having a surface area between 100 m2/g and 200 m2/g;
an absorbent glass mat separator between the positive electrode and the negative electrode; and
the natural organic expander material and the synthetic organic expander material comprising surface active molecules to provide for reduced deposition of a lead as a non-porous layer proximate to the negative electrode;

an electrolyte within the container;
one or more terminal posts extending from the container or the cover and electrically coupled to the one or more cell elements; and
wherein the battery has a dynamic charge acceptance greater than 0.6 A/Ah.
