How To Replace a Gameboy Cartridge Battery

About this video

How do you replace a Game Boy cartridge battery? The maker solders in a fresh CR2025 cell, using flux, a 3.8mm bit, tweezers and isopropyl alcohol for tidying the joints.

Good to know: Use a cell with solder tabs already fitted and solder only the tabs, never put an iron on the cell itself, and never short or charge it. Soldering means burns and fumes, old solder contains lead, and isopropyl is flammable.

Why watch it

The maker insists on soldering the new cell in, rules out the electrical tape method, and says the battery size depends on the game.
