I talked with a friend's dad yesterday. He worked at a plant that recycled batteries till it shut down about three years ago. He confirmed to me that most of the plates in the batteries have zinc, and copper in them. As well as several other alloys. The real problem in melting them down is the sulfuric acid that turns to a gas. When it contacts any moisture it goes back into its acid state. That means lungs, and eyes for humans. If it contacts the eyes they will be gone in minutes. If it hits the lungs the person would most likely be dead in a short time.

'They are just not worth the risk involved. Not only that the acid is still in the metal. The ingots that they get from melting the alloy down is used to make more batteries. It is not good for anything else. If used to make bullets it would be highly corrisive in the barrel of a gun. Like pitted with rust in a few minutes based on what sulfuric acid does to steel.
