and you can use other acids to make batteries but you just have to know which ones

A simple demonstration is to take a lemon and stick a strip of copper and another of zinc into it.
You could take some lead fishing weights and smash them flat. Suspend both into sulfuric acid solution (about 25%) careful, this burns. Then you could charge it up, and it will run a small light bulb.
