Li-Ion Rechargeable Battery Replacement for Game Boy Advance SP

The installation went off without a hitch, I didn't have to force or squish anything or hook it up to an external charger... Fits in an original AGS-001 just like the O.E.M. battery did!

Bought the battery as a replacement for the original battery that had started failing and now everything is working perfectly :)

Was worried about whether or not the battery would fit because of other reviews, though mine went in without any struggle [I've had more trouble changing the batteries in Wiimotes lol]. My SP is an AGS-001; if you have an AGS-101, this battery will probably not fit, though there's other batteries out there designed for the AGS-101

Overall excellent battery, excited to finally start playing again

867/850mAh on my tester.

Fits perfectly in my original shell... what more is there to say?

I got this it works and the battery life seems as advertised but it was an extremely tight tight fit in my ags 101

The batteries are indeed long lasting but they barely fit inside the battery slot on a lot of my GBA SPs and require a very tight squeeze to fit inside.

Warning do not use this battery back on your original shell housing as it will literally crack your entire back piece in half of how tight the fitting is. Upon squeezing the pack in it just cracked in half, so disappointing losing my original shell..
