Lemon Battery Kids Can Make
The goal of making a lemon battery is turning chemical energy into electrical energy, creating enough electricity to power a small LED light or a watch. You can also use limes, oranges, potatoes or other acidic foods. This experiment can be educational for children, with adult supervision.–Sciencing, Lemon Battery Facts
Simple Lemon Battery Made with Household Materials
When your kiddo comes home with news that it is science fair time at school a quick, easy, and educational option is the lemon battery. Recently, our two older kids, ages 7 and 9, presented ‘Lemon Power’ to their classmates and they were all awe struck.
Who wouldn’t be fascinated by using a lemon as a battery?

The process is simple and fun for the entire family.
Supplies You Need to Make a Lemon Battery
- 4 lemons
- 4 galvanized nails
- 4 pieces of copper (you can even use a copper penny, copper strip or copper wire)
- 5 alligator clips with wires
- A small light to power up
How to Do a Lemon Battery Experiment
Roll and squeeze the lemons to release the lemon juice and pulp inside.
Insert one galvanized zinc nail and one piece of copper or copper coin into each lemon with a small cut.
Connect the ends of one wire to a galvanized nail in one lemon and then to a piece of copper in another lemon. Do this with each of your four lemons until you have them all connected. When you are finished you should have one nail and one piece of copper unattached.
Connect the unattached piece of copper (positive) and the unattached nail (negative) to the positive and negative connections of your light. The lemon will act as the battery.
Turn on your light and voila you have powered up using lemon power.
Fruit Battery Science Experiment
Once the light turns on and your littles realize that it is being powered by the lemon battery they created, have your camera ready because the smile on their face will be priceless.
The end result is not only a greater understanding but also a greater appreciation for the lemon whose uses far exceed being used to simply make lemonade.
