I only know a few things about batteries, and here they are.

1. If you put the end of a 9 volt battery on your tonge it will shock you
2. It contains battery acid and copper
3. If you break a battery open and it gets on your skin, it will burn your skin.
4. They can be so small that they can sit on a dime, and so big they can power a car.
5. They are used for most modern day electronics
6. Some are rechargable!

What I would like to know about batteries.
How do they work?
When was the first one made?
How big is the worlds biggest battery?
Who discovered how to make batteries?
How do you make them?
