What Is A Lemon Battery?

A lemon battery is made up of two metallic electrodes comprising of two different metals. Lemon battery is just a small experiment which shows how batteries work. Although the lemon battery is not strong enough to make a light bulb work, however it is strong enough to power up a LED (Light Emitting Diode).

The lemon battery is also a very common experiment which is projected in many science textbooks around the world.

To make a lemon battery you need two different metallic objects, most commonly used objects are a Galvanized Nail, a Copper Coin and a juicy lemon. Although potatoes and apples can be used, but lemon is preferred as it has more acidic value.

The lemon used in the experiment should be disposed of immediately as it becomes poisonous because of the dissolved copper salts.
