How to Make a Lemon Battery

When life gives you lemons, the EEME team makes batteries! We then used the lemon batteries to power one of our hands-on projects - Project Genius Light.

Check out the video of Operation: Lemon Batteries:

If you want to build your own lemon batteries, here are the parts your need:

  • Lemons - the bigger, the juicier the better!
  • Zinc - we bought galvanized roof flashing from Home Depot and cut smaller pieces out ourselves with metal shears. You can also use galvanized nails.
  • Copper - we bought the thinnest copper rod from Home Depot in the electrical department.
  • Wires - we used 24 gauge stranded wire. Any color works. You will need wire strippers to strip the ends of the wire to expose the metal strands/core.

The video should show and tell what you need to do to make the batteries. We tried to keep the video short and to the point. For more information about how the electronic components and circuits work, check out our online lessons and monthly hands-on projects.

In the meantime, share this cool project with friends and family. Drop us a note if you have any questions or feedback!

Enjoy and happy building!
