Hey! the lithium battery in my GBA SP has finally begun to lose its charge. After a solid 6 or 7 years of use, it only lasts about a good hour or so before needing to be plugged back in. Which is understandable.
That being said, I use my GBA for LSDJ (and potentially in the future, nanoloop), so I'm looking to buy a replacement. I've checked out a couple of batteries on deal extreme however their reviews have me wondering whether or not it's a good deal even for a low price...
So I wanted to ask, has anybody bought replacement batteries before? What would they recommend? And how long would these batteries last?
