A home made battery can be made using the Voltaic method. Professor Alessandro Volta in the 1800s used zinc and copper discs each separated by cardboard soaked in slightly salty water.
By taking two wires, one from the top and the other from the bottom of the pile, you should get a voltage. The capacity will be determined by the size of the discs and the number of pairs of discs. Each pair is called a "cell".
If you get it right you should be able to run a small dc fan or a light a bulb if you choose ones that will run on the voltage the pile produces.
