Batteries are made of mostly lead but have a host of all sorts of nastier chemicals and heavy metals mixed in. Yah it can be done but what are you doing with all the environmentally nasties left over from the process.
Zinc is not as big an issue as some people make of it. 2-3% is a non issue and actually adds hardness. Too much zinc and lead will become a porridge.
