How to Replace Game Boy, Game Boy Color & GBA Save Batteries Properly

A customer recently asked if I had a video showing proper Game Boy save battery replacement, so I made a full walkthrough covering both Game Boy Color and Game Boy Advance cartridges. In this video, I show how I remove and replace solder-tab save batteries using proper tools, flux, solder wick, and safe soldering technique. I also cover the difference between common Game Boy cartridge batteries like CR2025 and CR1616, why tabbed batteries should be used, and why I do not recommend soldering directly to a standard coin cell battery. This is intended as a practical repair guide for anyone working on original Game Boy, Game Boy Color, or Game Boy Advance cartridges that no longer hold a save.
