NES Game Battery Replacement and Cleaning
About this video
NES save battery replacement is the job here, along with cleaning the cartridge contacts. The channel also mentions cells with solder tabs for anyone who prefers to solder the battery in.
Good to know: Leaked residue is corrosive. Use a cell with tabs fitted, solder only the tabs, never put an iron on the cell, and never short or charge it. Soldering means burns, fumes and lead. The channel sells the battery and bit.
Why watch it
The maker lists the 3.8mm bit needed to open an NES cartridge and a tabbed battery option, so the tool list is worth reading before you open anything.
