Seems fine so far

Works great so far, holds a charge much longer than my old battery. However the packaging was a bit strange, it came wrapped in plastic and foil and the screwdriver was rolling around loose in the envelope, there was no other packaging to speak of. But if it works it works I guess.

Exactly what you’re looking for.

These are great replacement batteries for Gameboy Advance SP. They seem to last a long time and don’t take too long to charge. I ended up buying two because they’re so great. The shipping was pretty fast.
