The Apple Battery Exchange site lists the A1601 model with a serial number range of "6C519 - 6C552 ending with S9WA, S9WC or S9WD." My battery is A1601, ser. no. 6C5244 ending with S9ZD. I'm in the clear, right? Sorry for the dumb question, but I'm a dumb guy. And paranoid about household objects that can turn my home into fiery doom.
