An advantage of cmos is that it can operate over a wider range of dc supply voltages (typically 2 v to 6 v) than bipolar and, therefore, less expensive power supplies that do not have precise regulation can be used.also batteries can be used as secondary or primary sources for cmos circuits.in addition, lower voltages mean that the ic dissipates less. After replacing the battery in the same orientation, you can replace the computer cover and tighten the screws.

The worse that usually will occur is the bios not saving your settings once your main power has been disconnected (like pulling the main power cable for a certain period, or turning off your system via a power center / strip, etc.) as without a cmos battery to keep the bios data alive, then it wont keep them saved. As long as the battery is showing about 2.92 or higher its fine and still useable.
