Just confirmed it on a Brazilian 12C (CNA 81306005) and it worked as expected. It's a CR2032 one, so it's CMOS.
One thing comes to mind though: back when this calculator was acquired (my wife was doing her MBA) a professor warned about being tempted to buy the Platinum version, as it would yield wrong results and, if that happened in a test, it'd result in the student failing. I think that, back then, the Platinum was the first to run on ARM emulation.
