Yes.To be solid.

Some D batteries are made up of alkaline, zinc-carbon, lithium iron disulfide, nickel cadmium, and nickel-metal hydride.
Batteries typically use metals such as zinc, lithium, and nickel in various forms like compounds or alloys to generate electrical energy. The type of metal used depends on the specific battery chemistry and its intended application.

Yes. but it isn't the only metal used for batteries.
They reduce the use of metal used to make them. (i.e. when you get disposable batteries the metal is disposed) but if you recharge batteries, it will reduce the costs of making.
I imagine metal detectors are different. Mine uses two 9 volt batteries.

Zink
Nickel nimh stands for "NIckel Metal Hydride"
Metal isn't used at all, Automotive Batteries are made of plastic with lead plates, if it were just metal it wouldn't leas as the battery works off of electrolysis is the case was made of metal if would be corroded and eventually leak out all the acid. so to answer you question... NONE only lead for the internal plates, Stainless may potentially be used but lead is a cheaper and more common material in batteries
Galena is lead sulfide, an important source of the metal lead. Storage batteries, like the one in your car, have lead plate and posts- so it is likely that part of your battery was MADE from galena.
