A battery can make your bios/system clock slow but I'm not sure about making it fast. Any clock that runs on a battery should slow as the battery loses juice. Could it perhaps be getting to much juice and thus making it fast? If not could be something w/in windows messing w/ your system clock. Also since this is only when your system is already running that kinda does take the cmos batter out of the picture anyways.
