Possible MH Engine Battery with Amp Hours Too? UPDATE

Don't all batteries have a cranking amp rating as well as an amp hour rating, whether or not it's on an external label? Most batteries can do both, start a car, and/or power DC appliances, albeit at different rates of discharge and at varying efficiencies, depending on the physical limitations of the battery itself? Some batteries do one task better than the other, but they can all do both, as far as I know, within physical/chemical capacity limits.
