Earlier quoted context omitted.
FWIW, I have a 5 year old dell XPS whose battery I could both find an replace easily. That is one of the advantages of the bigger name brands, replacement parts are generally a lot easier to find.
Yeah, but is it OEM? Even big names like Dell don't support their parts for that long, and you have to resort to getting sketchy third-party parts from China, or rolling the dice on a used OEM part.
