CMOS Battery | Reliable Power for Your Motherboard's BIOS Settings

A CMOS battery is a small but critical component that provides backup power to your computer's motherboard, preserving essential BIOS/UEFI settings, system time, and date when the computer is turned off or unplugged. This includes boot order, hardware configuration, and system preferences, ensuring your computer starts correctly every time.

When a CMOS battery fails, you may encounter issues like reset system clocks, BIOS configuration errors, or boot failures. Replacing an old or depleted battery restores stable power to the CMOS memory, preventing data loss and maintaining system integrity.
