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!
