The CMOS battery is a small battery fitted on the motherboard of your computer. It has a life of around five years. You need to use the computer regularly to extend the life of the CMOS battery. The computer power supply increases the availability of a standby current and hence increases the life of the battery.

How long does motherboard CMOS battery last?
CMOS battery
The memory battery (aka motherboard, CMOS, real-time clock (RTC), clock battery) is generally a CR2032 lithium coin cell. This cell battery has an estimated life of 3 years when power supply unit (PSU) is unplugged or when the PSU power switch is turned off.
What happens when CMOS battery dies?
If the CMOS battery dies, settings will be lost when the computer is powered down. You will probably be asked to reset the time and date when you start the computer up. Sometimes the loss of settings will prevent the computer loading the operating system.
When should I replace my motherboard battery?

How long will a 2032 battery last?
Answer: The CR 2032 battery is rated at 210 mah which means that if a 210 mA load was placed on it, it should last one hour. However, when used to provide standby CMOS power it is much less than that, more on the order of 10 microamperes, so it should last about 21,000 hours of actual use.
Why do motherboards have a battery?
All personal computers have a small battery on the motherboard that provides power to the Complementary Metal Oxide Semiconductor (CMOS) chip, hence the name CMOS battery.It provides power even when the computer is off and allows the CMOS to save all the settings [source: Indiana University].
Will a computer boot without a CMOS battery?
You can generally run your PC without the CMOS battery as long as your default CMOS parameters are compatible with the operating system, or as long as you manually set the appropriate CMOS parameters after every time the system loses power.
Does CMOS battery stop PC booting?

Do all motherboards have CMOS battery?
Yes, all personal computer motherboard have a small battery on the board to provides power to the Complementary Metal Oxide Semiconductor (CMOS). That is why it is called CMOS battery.
How long do you leave the CMOS battery out?
Wait five minutes before reseating the battery. Clearing the CMOS should always be performed for a reason – such as troubleshooting a computer problem or clearing a forgotten BIOS password.
Will bad CMOS battery cause shutdown?
If a CMOS battery dies while the system is on, does it have ability to shut your system down? no it wont.. most times when you have a shut off is due to an over heat or a part failure.
Why does CMOS battery fail?
CMOS battery takes care of the BIOS functions of your desktop or laptop. That is exactly it keeps track of date and time even when your system is shut down. A failed CMOS battery can cause your device showing incorrect date.
