Most GBA games utilize SRAM to save game data. For those who don’t know, SRAM is simply a computer chip that saves game data. However, some Game Boy Advance games utilize a battery to store save data and for other functions.
So why does this matter? Well, not all batteries last forever, so when your GBA battery dies, all your save data will be lost! Also, you will not be able to save your game progress anymore.
Replacing a dead GBA game battery will require you to open the cartridge and solder on a fresh battery.
Here’s the list of GBA games that require a save battery:
- Baseball Advance
- Boktai 2: Solar Boy Django
- Bomberman Tournament
- Breath of Fire
- Breath of Fire II
- Castlevania: Circle of the Moon
- Castlevania: Harmony of Dissonance
- Dragon Ball Z Collectible Card Game
- Hamtaro: Ham-Ham Heartbreak
- Kirby: Nightmare in Dream Land

Note: Only the early releases of Metroid Fusion and Metroid Zero Mission use a save battery. The re-releases utilized SRAM.
