Most motherboards use a 2032 battery.
A slot on the motherboard intended to hold the CMOS battery.
There are none. One is a battery which is used to provide passive power to the CMOS chipset to keep it from clearing itself.
CMOS battery
The CMOS RAM battery is commonly referred to as the "CMOS battery." It is typically a small coin-cell battery, often a CR2032 lithium battery, that powers the CMOS (Complementary Metal-Oxide-Semiconductor) memory. This memory stores BIOS settings and system time when the computer is turned off. If the CMOS battery fails, users may experience issues with system settings and time retention.

BIOS (basic input output system) is the menu system programmed into the firmware of your motherboard which allows you to change its settings and input some basic hardware information. CMOS (copper metal oxide semiconductor) is a type of battery. It is the type of battery most commonly used on motherboards to power the circuit which remembers the BIOS settings and system time. Without a CMOS battery, this data will be lost every time the system is powered off. In common nomenclature, these two phrases are often used interchangeably. Some people will refer to the BIOS menu as the CMOS menu, and will refer to the CMOS battery as the BIOS battery.
Chances are that the CMOS Battery on the motherboard is dead and needs to be replaced. Without this battery, the computer can not remember the CMOS settings when the power is turned off.
You would dispose of such as you do any other battery.
