Open the N64 cartridge

You'll need a 3.8mm Gamebit security screwdriver to open the cartridge. Use it to remove the two screws on the back and open the case.

  

Remove the metal RF shield

Use a small Phillips screwdriver to remove the small screws at the bottom of this casing.

 

Locate the battery

The battery is located on the same side of the cartridge as the microchips.

Take a look at the date code if your battery has one, some are original and from 1998 era (98-12 is December 1998).

No wonder they’re flat now and don’t save games.

 

Desolder the battery tabs

Locate the two large tabs on the other side of the board sticking up from the battery. Heat each up with your soldering iron and use your solder sucker to desolder them.

Solder in the new battery

Your replacement battery has one wide tab and one narrow tab. This makes orientation easier as the battery is not reversible. Solder the new battery in place.

NOTE: The positive + tab is the one on top of the battery.

 

Reassemble everything

As always, assembly is the reverse of disassembly. You're ready to play!
