Is your Nintendo Gameboy Advance GBA game no longer saving your games? This is the correct replacement coin battery you need.
You will also need a triwing screwdriver (sold on our website) to open the GBA game cartridge.
Instructions on how to perform the replacement using black electrical tape are on our website under Repair Center. No soldering required.
If you can solder, we also offer this battery with solder tabs. Or, you can order the game battery replacement service and let us do it for you, and clean your game contacts at the same time.
