It is a replacement battery for Pokemon Gold, Silver and Crystal and a 3.8mm Gamebit to open the cartridge. (I also have batteries for other Pokemon games and for Nintendo NES, Super Nintendo (SNES), Nintendo 64, Sega Mega Drive / Genesis and Sega 32X cartridges, please look at my other items).

If your game have saving problems, it's because the battery is empty, you need to change it to fix the problem.

Changing the battery is very easy, you have to desold the battery on the cartridge and sold this one in the same place respecting the polarity.



I have a lot game/accessories for retro and recent consoles on my shop !
