There is only one motherboard battery, and it will permit the bios to retain your saved settings.

Hi newcomer and welcome to the Tom's hardware forum.

The CMOS battery is used for the mobo to keep the settings that u save in the BIOS like the date, time and OC preferences. All mobos have this battery and like a normal battery have a life time.
