Game Cart Backup Battery


Replacement battery to restore save game memory functionality in classic game cartridges

Is your game cartridge not remembering your save games? It’s likely the backup battery inside the cartridge has dried out and run out of juice! Pop it open and replace the old battery with one of these replacements to restore battery saving features.

Before ordering, please open your cartridge and verify the battery type needed. We have attempted to group battery types by systems, but can’t inspect absolutely every cartridge!

These replacement batteries come with pre-welded tabs, and are a solder-in replacement, so you will need some minimal soldering skills and tools to complete this change.

Compatible Systems

Nintendo 64, Nintendo Gameboy, Super Nintendo
