The Nintendo Game Battery Replacement Kit includes a Nintendo 3.8mm Gamebit Security Tool used to open NES SNES & N64 games for easy access for cleaning and repair and a coin battery to replace your old one. If your games no longer save this is the kit for you!
Illustrated instructions on how to replace the battery are on our website under the "Repair Center" section at the middle of the top bar on the home page.
These batteries do not need to be soldered in place, please read our Repair Guide for how-to. If you would prefer to use the game batteries with the solder tabs welded on, we also offer those.
Optional magnetic bit handle fits both 3.8mm and 4.5mm bits, and any standard 1/4" hex shank bit. The 3.8mm game opening security bit in the kit is difficult to hold
with just your fingers. If you don't have a magnetic screwdriver
handle that accepts interchangeable 1/4" hexagonal shaft bits, or a
power driver or power drill, you may want to add our magnetic bit
handle to your order.
