It is a batch of 10 spare batteries for Nintendo Nes cartridges, super nintendo (SNES),Nintendo 64, Sega Mega Drive / Genesis, SEGA 32X as well as a 3.8mm gamebit tip to open the cartridgesNintendo . I also have an ad in my shop at the same price with a gamebit 4.5mm tip for Sega cartridges. (I also have batteries for games from Game Boy, Game Boy Color and Game Boy Advance, look at my ads).

If your cartridge has problems backup, there is a good chance that the internal battery will be exhausted, it must be changed to enjoy its game cartridge again.

Changing the battery is very easy, you have to dry the battery in the cartridge and weld it instead while respecting the meaning.
