CR2032 Battery holder - sanity check

[DonFL]

You need both coin inserted. It seems it gets 6v dropped to 2.85v and this works.

So you're saying its not meant to be two 3V cells in parallel, its meant to be 6V, and then regulated on-board?

I'm very leery of that in that the AAA battery holder looks like its 2 AAA cells, so 2x1.5V, a 3V output...would expect the 2032 holder to be the same design since its intended for the the very same function. Schematic for the 1 GB board that's posted on the wiki also indicates, if I'm interpreting the schematic correctly, 3V for RTC, with a direct connection to the PMIC chip, which also shows a spec of 3V max for RTC input.
