There have been multiple times where I have needed a 9v battery lead/clip but did not have one. Just the other day I was working on a project that I wanted to hook a 9v up to and like before I did not have any 9v battery clips, so I made my own.
I made my battery clip out of a dead 9v battery. The first thing I did was take some pliers, and after finding where the battery casing ends meet, start to pry at the casing at the top of the battery. I continued to work at opening up the 9v casing to the point in which I could slide out the piece of plastic that has the 9v battery terminals on it. When I got this out I threw away the mangled up casing along with the dead cells that were in the casing.
Now it’s time to solder. I got two pieces of stranded wire to solder onto the 9v battery terminals we just saved from the dead battery. I soldered each wire to the back side of one of the terminals. When soldering the wire I realized that what used to be the battery’s positive terminal would snap onto a 9v battery’s negative terminal, and vice versa. So I planned my wire colors accordingly.
At this point the battery clip is done, but to make mine look cleaner I took some 1/2″ diameter heat shrink and stuck it over the clip. After shrinking it with a heat gun, I used an Exact knife to cut around each terminal. I think this made it look a little more professional.
