DIY Battery Holder

A battery holder is a compartmentalized device used for holding batteries. It comes as either a plastic case or a mounted plastic holder. Learning to create your own battery holder can save money and make storing batteries easier and more organized. 

What you need:

• Glue gun


• Glue gun glue


• Pliers


• Batteries (best to use dead batteries)


• Dremel cutting tool


• Dremel mat


• Helping hands


• LED or voltmeter
  
  

1. Cut the metal piece twice the size of the diameter of the battery.


2. Bend the metal in a 90-degree angle. If you intend to made make the battery holder with thread, drill a hole through one of the sides of the metal.


3. Make a second piece.


4. Hold together the negative side of one of the dead batteries with one of the metal contacts using the helping hands.


5. Glue the battery and metal together.


6. Repeat with the second battery on the positive side.


7. Trim off the excess glue from the face of the unglued side of the battery.


8. Hold the positive and negative batteries together and glue.


9. Apply the glue so that the batteries are well covered but leave one side open.


10. Pop both batteries out of the holder. You may need to trim off some of the glue first.


11. Shape and refine the battery holder using sandpaper and a utility knife.


12. Cut and shape the open side of the battery holder so that the batteries can easily slip in, do not cut off so much glue that the holder is no longer rigid.


13. Use a voltmeter or an LED to test the holder.


14. Create a metal contact that has a rectangular shape and is a bit longer than the bottom of the battery.


15. Put the negative side of the battery on the metal contact. Do not let the metal contact touch the positive side of the battery.


16. Add some glue between the edge of the battery and the metal first, then glue the bottom of the battery and metal together.


17. Repeat the metal contact and glue process with the positive side of the metal contact and apply the glue.


18. Pop the battery out of the battery holder.


19. Sand and cut to shape and refine the holder.


20. Test with a voltmeter or LED.
