The simplest way to check the CMOS battery's health is to use your computer itself as the test device. The battery's whole job is to back up the BIOS settings when the computer loses power, so if you deliberately cut power to your computer, you'll know if it's doing that job. It'...
What is a CMOS Battery? A CMOS (Complementary Metal-Oxide-Semiconductor) battery is a small, coin-shaped battery found on a computer’smotherboard. It provides power to the CMOS chip, which stores important system information such as the date, time, and hardware settings in the CMOS memory....
Related: How to Check Your BIOS Version and Update it How to Test Your CMOS Battery Now, the fastest way to test your CMOS battery is by checking its voltage with a digital multimeter. To do that, though, you'd have to open your PC's case and remove the battery, and you'd need...

4. Remove the CMOS battery 5. Leave the system in this state for 4 hours. 10 minutes is enough in most cases but if that yields no result then to be absolutely certain CMOS is clear I recommend 4 hours. 6. Place the "Clear CMOS" jumper back in its original position 7. Replace the...
CMOS Checksum Error CMOS Battery Failure System battery voltage is low If your PC frequently displays an error message about the BIOS settings being cleared, there's a high chance your CMOS battery has been depleted. CMOS coin cells typically have a lifespan of three to five years, so even ...

As the CMOS battery is primarily responsible for powering the RTC, it may lead to incorrect date and time on your PC. While this can be overcome by synchronizing your PC’s date/time with the Internet, it is a crystal-clear symptom of a failing CMOS battery. ...
