Desktop
There is a computer at my job that presents this message:
"Alert: System Battery Voltage is low. Press F1 to continue or F2 to enter set-up." Is this related to the CMOS or is this another problem. Thanks for any advice.

Assuming that this is a desktop system, I would agree that the BIOS is monitoring the CMOS battery and the battery is low and needs to be replaced.
Most likely the battery is a CR-2032 Lithium coin cell.
IF you leave AC power connected while changing the battery, you should not loose your CMOS settings.
On nearly all ATX systems, the CMOS battery is only used when power is physically shut off to the computer power supply, or in the case of a power outage.
Otherwise, as long as the power supply is plugged in, there is 5 volt DC power on the motherboard at all times.
