N64 Controller Pak Battery Replacement
About this video
Why has an N64 Controller Pak stopped holding saved games? The video goes through changing its battery, and the maker adds a notice that the work is done at the viewer's own risk.
Good to know: Leaked battery residue is corrosive. 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 brings burns, fumes and lead.
Why watch it
The maker says plainly that electronics is not their trade. Short at six minutes, it stays on one job, a Controller Pak that has stopped saving games.
