It is a lot of 100 replacement batteries for game cartridges : Nintendo
NES, Super Nintendo (SNES), Nintendo 64, Sega Mega Drive / Genesis, Sega
32X. (I also have batteries for Game Boy, Game Boy Color and Game Boy
Advance games, please look at my other
items).
I can mix the 3 types of batteries if you want. The price won't change,
the shipping fees can change a little bit. Please send me a message for
that.
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.
To open the cartridges, you need a 3.8 mm Gamebit (Nintendo cartridges) or a 4.5 mm Gamebit (Sega cartridges) that you can find in my shop.
I have a lot game/accessories for retro and recent consoles on my shop !
