7/11/23 - We have noted that our new batch of batteries has a fitment issue due to height clearance. This can cause the battery cover to not sit flush with the shell. The supplier suggests pressing the battery with mild pressure to reduce height. Returns/Refunds are not accepted for this product. Please see product photos for example of the fitment issue you may experience.

This Rechargeable Battery Pack delivers up to ten hours (varies depending on your console) of non-stop fun on your Game Boy Advance® SP system.


  • Fit will be tight initially upon install but this is intentional. The SP batteries are not designed to be removed for years upon initial insertion. 
  • 850mAh 
  • 3.7V


  • 1x Battery


  • This product is not designed, manufactured, sponsored, endorsed, or licensed by Nintendo® of America Inc in the United States and/or other countries.

So far so good

Gonna see how it fares after a few charging sessions but it brought my system right back to life

Ramiro L
Failure after two months

Started to bloat and even cracked my battery cover after light to moderate use. Unsafe to use (for me)

Thanks for your review! Please reach out to us at so we may look into this further with you.


Battery thicker then space within shell allows for. The battery cover does not sit flush on YOUR shell when installed correctly with this battery

Great Battery

The first time fit was a little snug because the battery's wrap was a touch loose but a little creasing in the corners fixes that. From a functionality standpoint it's perfect. No random restarts, no overheating and it charges as it should. Recommended!

Good so far, but battery door isn't flush now.

I bought this battery to put in a -001 SP. The capacity is higher than an OEM battery which is nice. The battery fits in the console and the battery door closes over it, but the corners of the door stick up a little. For me, this isn't a deal breaker but I can see it being so for some people. Haven't tested the battery life and charging time yet but I don't have a reason to think those won't be satisfactory.

All ribbon cables should have no bends or creases in them. If you are unsure how to perform a dry run, please contact our support team and we will be happy to help. Backlight kits that have been installed are not eligible for replacement or return. If a backlight/LCD is returned and shows any signs of having been installed, it will not be eligible for a refund.
