What battery does my motherboard need?
CMOS battery The memory battery (aka motherboard, CMOS, real-time clock (RTC), clock battery) is generally a CR2032 lithium coin cell.
Do motherboards still have CMOS battery?
CMOS RAM requires a battery; the settings would otherwise be lost when the PC was switched off. Modern computers don’t use CMOS RAM anymore. Meanwhile, modern UEFI motherboards store settings on flash memory or on the computer’s hard disk drive. No battery is necessary on these systems, but you’ll often find it anyway.

Can I use any CR2032 as CMOS battery?
But they are for the most part, simply Lithium coin cells of 3 V output usually 2032 or similar. Common sizes that can be used for CMOS backup applications are 1632, 2025 and 2032.
Why is there a 2032 battery in my computer?
Every PC motherboard has a battery. That battery serves two purposes: to feed the configuration memory (also called CMOS) and to feed the real time clock of the computer (the one that show the date and the time). To buy one of these batteries, all you have to do is to look for a model CR2032 one.
Can PC work without 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.
What happen if CMOS battery died?

How long do motherboard batteries last?
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 do I know if my CMOS battery is bad?
