Game Boy micro - Replacing the Rechargeable Battery
Please read before attempting to replace the battery:
- Do not use an unlicensed battery. For information on ordering a battery directly from Nintendo, please click here.
- Always perform a full charge before the first use with the new
battery.
- You will need a small philips head screwdriver -- sometimes
called a jeweler's, micro, precision, or miniature. The best size
tends to be #00. This is a very small screwdriver that can be
purchased in most hardware stores.
- Remove all games, the AC Adapter, and turn the system off before
attempting to remove the battery.
- Using a small philips head screwdriver -- sometimes called
a jeweler's, micro, precision, or miniature (#00) -- unscrew the
small philips head screw on the left side of the Game Boy micro.
Once the screw is completely loose, remove the battery cover.

- Remove the battery pack from the battery compartment and carefully unplug the battery connector from the Game Boy micro. For
assistance in disposing of Lithium Ion batteries, it is also a
good idea contact a local solid waste disposal facility.


- Carefully plug the connector from the new battery into the socket. To fully insert the plug, it might be necessary to use a blunt-tipped object, such as one of the ends of the Faceplate Ejector Tool.
Important note: Do not use any type of metal object to insert the plug as this may cause permanent damage to the system.

- Replace the battery pack, making sure to fold the loose wire into the small gap between the battery and the plug, then replace the battery cover.
- Replace the battery pack and battery cover, and use the screw you previously moved to secure the battery cover onto the Game Boy micro.
- After replacing the battery, the new battery must be charged for approximately 2 1/2 hours before the Game Boy micro can be used.
