How to Make a Lemon Battery?

Making a battery is one of the interesting concepts in the school curriculum. Are your children familiar with batteries or their benefits? If not, you can teach kids to make batteries using lemons at home. To teach them how to make a lemon battery, you can conduct science experiments for kids. These experiments enable children to experiment with the things easily accessible to them and make something creative. With this experiment, kids can learn how the lemon acts as an electrolyte to produce electricity from them. 


Batteries are devices that convert chemical energy into electrical energy. A chemical reaction occurs between the two metals and the electrolytes to produce electricity. You can teach kids how to produce electricity with the help of lemon batteries. You can make these batteries at home to demonstrate how chemical reactions take place to produce electricity using lemons. Conducting these science experiments for toddlers or kindergarten kids can develop an interest in performing experiments and learning science with utmost dedication. 

Easy Science Projects: How to Make a Lemon Battery?

How would you teach kids to make a battery at home? The best way would be to provide materials that are easily accessible and convenient for kids to use. You can teach kids how to make a lemon battery by conducting a small experiment. Little ones must know how a battery works and its benefits in today’s world. You need to provide instructions or procedures to kids that are extremely easy and understandable for them to follow. Did you know that a lemon can produce about 9 volts of electricity? To teach the mechanism of how electricity is produced from lemons, you can perform the experiment given below.

Aim of the Project 

The project aims to perform and observe the experiment using lemons and materials easily available at home under the guidance of elders. 

Materials Required 

  • Two lemons
  • Two copper strips or wires
  • Two galvanized nail
  • Two wires 
  • A voltmeter


  • Take two galvanized nails and insert them into each of the lemons. 
  • Take two copper strips or wires and insert them into each lemon. 
  • Take a wire and connect its ends to a nail of one lemon to a copper wire of another. 
  • Take a wire with one end connected to the voltmeter and the other end to a nail of one lemon to a copper wire of another. 
  • Observe and record the changes. 


In this experiment, kids can observe that lemon juice consisting of citric acid, acts as an electrolyte responsible for producing electricity. It converts chemical energy into electricity as the chemical reactions allow the flow of electrons from one metal to another through a circuit.
