It's been a very long time since I've seen a rechargable battery for the
BIOS memory power on a PC.  All the ones I've seen use a watch battery
cell.

NB:  I mean Personal Computer, when I say PC.  I don't work with real
servers, and I wouldn't call them a PC.

There's still plenty of CMOS technology around, but I haven't looked
into what's actually used with the BIOS, these days.

Out of the motherboards that I've looked at, the power to that section
has been diode and resistor coupled.  It'd be difficult to produce a
dead short to the supply from the battery terminals.

You wouldn't want to short some of those button cell batteries, they can
get damn hot.
