"but what is the "CMOS" battery"
http://en.wikipedia.org/wiki/CMOS_Battery
That's the long answer.
The short answer is that its a battery that allows your BIOS settings to be saved. Its usually a battery that's about the size of a nickel. Its very easy to find on most desktop motherboards, often harder to find on notebook motherboards.
They're usually held in with a small clip that can be released with a fingernail. Removing it for an extended period of time will cause any settings made in the BIOS to be lost and restored to their defaults.
