It is a lot of 10 replacement batteries for game cartridges : Nintendo NES, Super Nintendo (SNES), Nintendo 64, Sega Mega Drive / Genesis, Sega 32X and a 3.8mm Gamebit to open Nintendo cartridges. I also have for the same price an annunce with a 4.5mm Gamebit to open Sega cartridges. (I also have batteries for Game Boy, Game Boy Color and Game Boy Advance games, 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 !
