I’ve used some non-OEM expanded cell batteries back in the netbook days and they worked okay for about two years before drastically losing their ability to hold a charge. I’d recommend just sticking to OEM parts with proper electrical certifications just to help lower the chance of thermal runaways or things like that.
I ended up making a rather large amount of purchases from GOG: the entire catalog for Prince of Persia, Crysis, Crysis Warhead, Vaporum, Hotline Miami 2, and Men of War: Assault Squad.
I hope you feel better soon Perfect Dark!
