5. Troubleshooting a loose battery

Due to differences in printer resolution, there's a chance you may end up with a slightly 'loose' battery – meaning it moves around within the holder when you shake the module side-to-side. If this is the case for you, the looseness could compromise the contact between the battery and the stripped blue wire end.

There is a super easy fix for this! Use a small square of scotch tape to tape the stripped blue wire end to the center of the bottom negative (-) side of the battery. Then slide it back into place in the holder, positive (+) side up. This should fix any possible contact issues.
