Review on Rechargeable Lithium-Ion Battery Kit With Tool Pack For Nintendo GBA SP/Game Boy Advance SP - 850MAh Capacity by Julio Solano

This got here its affordable, and it works like brand new when I first got my GBA SP but better. The original SP battery was 600 mah, this is 850 mah, this last longer than the original battery. And can go for 6-8 hours of gameplay (depending on how much volume you use). I love it and if you have a GBA SP and it needs a new battery come get this one.
