The battery is on charge the rest of the time, 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.

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. -- [tim@bigblack ~]$ uname -ipr 2.6.22.1-41.fc7 i686 i386 Using FC 4, 5, 6 & 7, plus CentOS 5. Today, it's FC7.
