A lemon battery is a simple battery made for the purpose of education. Typically, a piece of zinc metal (such as a galvanized nail) and a piece of copper (such as a penny) are inserted into a lemon

Step 1: Potato Battery Homemade

Potato battery with zinc (left) and copper electrodes. The zinc electrode is a galvanized machine screw. The copper electrode is a wire. Note the labels − and + marked on the potato indicating that the copper electrode is the positive terminal of the battery. A short screw and nut connect the electrodes to the copper wires that have black and red insulating plastic coatings.

Step 2: Orange Battery DIY
