Axelford Posted November 9, 2019 Hello, I recently bought a bulk lot and to my surprise found a 4.5 battery box. I have a motor to go with it which is great, but inside the box it’s missing one metal contact. I am thinking of soldering but that might melt the plastic. Any ideas? btw the contact is circled in red in the photo. Share this post Link to post Share on other sites
sed6 Posted November 9, 2019 I would repair that by using a short popsicle stick to span the area the contact should be. I could affix a spring or something metal to the popsicle stick to make contact with the battery. Then solder a wire from the new spring to the backside of the tab it should go to. You could solder on that curved portion of the tab without melting the plastic. Good luck! Share this post Link to post Share on other sites
