Review on Rechargeable Lithium-Ion Battery Kit With Tool Pack For Nintendo GBA SP/Game Boy Advance SP - 850MAh Capacity by Danny Badasz
Was dead on arrival
I had to through it in the recycling bin because it was dead on arrival (battery was bulging) and I didn't want to risk it blowing up in my face. Not recommended as a replacement.
Pros
- Solid replacement battery & that massively useful tiny screwdriver it comes with is adorable!
Cons
- May not hold up well against intense gameplay sessions
