My black GBA SP of about 12 years died on me about 4-5 years ago or so. I bought a new lithium-ion battery that said it was rechargeable but I have no idea how to do that (I bought it off eBay). Funnily enough, it actually worked with this new battery until it ran out. Every time I try to charge it, the orange light lights up for 1 and a half seconds and then turns off. I do have a DS and an original GBA that work fine but I'd love to use this once again. Maybe it is time to just accept that it is gone and to probably buy a new one or just use what I have but is there a way to fix this?
