Understanding CMOS Battery Lifespan: How Long Do They Last?
Learn how long CMOS batteries last and factors that influence their lifespan.
0 views
CMOS batteries generally last 5 to 10 years. Their lifespan can depend on factors such as system usage and power quality. Regular use of your computer can help extend the battery life, as the system draws less power from the CMOS when it is powered on. If your system clock starts losing time or BIOS settings get reset regularly, it’s time to replace the CMOS battery.
