Product information

Description

Replacement CMOS/RTC coin cell battery for Lenovo systems, model C 82K2 E3. This externally mounted coin cell is intended to maintain BIOS settings and the system clock when the main power is disconnected. The battery provides backup power to preserve configuration data on compatible Lenovo motherboards and older desktop or laptop systems that use an external coin cell holder. It is a compact solution for restoring timekeeping and BIOS parameter retention after power loss or during motherboard servicing.

Advantages

The coin cell offers reliable long-term backup power for the real-time clock and BIOS memory, helping to avoid loss of system settings and time drift. Its form factor matches compatible Lenovo external holders for straightforward replacement without modifying the motherboard. The battery is lightweight and easy to handle, enabling fast swap-outs during repairs or maintenance. Because it is designed as a direct replacement, it reduces the risk of connectivity or fit issues that can occur with non-compatible cells.

Suitable for

  • Preserving BIOS/RTC settings on Lenovo motherboards that use an external coin cell holder
  • Replacing an aging or depleted CMOS battery in older desktops and laptops
  • System maintenance, repairs, and motherboard servicing where external coin cells are used

Key specifications

  • Type: External CMOS/RTC coin cell for motherboard use
  • Function: Provides backup power for real-time clock and BIOS settings
  • Form factor: Externally mounted coin cell compatible with Lenovo external holders
  • Typical use environment: Desktop and laptop motherboards requiring an external RTC battery

How to use

Power down the computer and disconnect it from mains power before attempting replacement. Locate the external coin cell holder on the motherboard or chassis and carefully remove the depleted cell according to the system manufacturer's access method. Insert the replacement coin cell with the correct polarity orientation, ensuring a secure fit in the holder. Reconnect power and check BIOS/UEFI settings and system clock; update date and time if necessary. Follow static-discharge precautions and the device manufacturer's service instructions while handling internal components.

Usage recommendations

Store spare batteries in a cool, dry place and replace the coin cell promptly when BIOS warnings or clock drift are observed. If the system uses CMOS-protected passwords or customized BIOS settings, record settings before replacement. Consult the Lenovo hardware manual for model-specific removal and insertion instructions to avoid damage to the holder or motherboard.
