After multiple drops from the slot in my finishing and framing nail guns, one of my batteries cracked open, exposing the cells inside. With a few household materials, it's easy to repair the damage and correct the problem.
Step 1: Gather Materials
You're going to need:
-Something spongy that you can cut into a little piece
-Hot Glue(Liquid Nail or epoxy is better if you have it and will keep the battery secure if you drop it again)
