900 mAh Battery for Game Boy Advance SP

Huge Improvement

I recently pulled my old GBA SP out of storage and the original battery was still functional but could only hold a charge for maybe an hour or so. Since swapping out the OG battery with this 900 mAh battery I've enjoyed several long gaming sessions before even seeing the low battery light. The new battery is physically smaller than the original but the included adapter allows it to fit basically perfectly. Highly recommend.

Works and fits(kinda) as advertised.

the bracket is a little thicker than original battery. Trimmed it with an exacto knife and it fits decently. Other than that, it was plug and play.

The battery's contact pad was loose. I put it in my Game Boy Advance SP to test it out, and it works, but I'm really cautious about the idea of leaving it in for an extended period of of time.
