Step 1: Tools and Supplies
Flat head screwdriver
A 9 volt battery with a metal case (I recommend Duracell)
Two small bits of wire
Step 2: Open the Case
Use your screwdriver and pliers to carefully pry back the top of the case and empty all the contents of the battery.
Step 3: What You'll Find Inside
What should come out of the battery is 6 AAAA cells, the bottom cover, the top cover, and the case itself. If you had lollipops, a small rodent, and a sock come out of the battery then you may have done something wrong.
Step 4: Making the Battery Clip
Heat up your soldering iron and solder two your two wires onto the contacts on the back of the top cover.
Step 5: The Case
The Battery case can have many purposes. Some examples are: Flashlights, Holders for small electronic parts. Use your imagination. Check out my other instructable on how to turn it into an electric hand warmer/heater https://www.instructables.com/id/Electric_Hand_Warmer/
