## Long description

CMOS Battery Lenovo 20VF 5B10S34080 is a motherboard backup coin cell designed to maintain BIOS settings and the system clock when the main power supply is disconnected. It supplies a stable low-current source to the motherboard’s CMOS memory so time, date and BIOS configuration are retained during storage, transport or maintenance. The battery is intended for Lenovo systems that require a compatible coin cell for reliable retention of firmware settings.
Advantages
The coin cell provides consistent low-current output suitable for long-term standby duty, ensuring that BIOS memory and real-time clock remain powered between uses. Its compact form factor fits directly into compatible motherboard holders without modifying the board, and the design supports easy replacement during repairs or upgrades. Using a matching backup battery reduces the need to reconfigure system settings after power loss.
