Product information

Description

Lenovo 5B10S34066 lithium CMOS coin cell battery delivers a nominal 3V output and 220mAh capacity to maintain BIOS/CMOS settings and the real-time clock on compatible Lenovo motherboards. Intended as a motherboard backup power source, this coin cell supports stable retention of configuration data when the main power is disconnected and is suitable for use in laptops and desktops that require the same electrical parameters and physical format.

Advantages

This lithium CMOS coin cell offers a consistent 3V voltage and 220mAh capacity to provide long-term backup for system settings. Its compact coin form factor is designed for direct replacement in motherboards that accept CMOS coin cells, ensuring proper fit and electrical contact. The battery is tailored for low-drain standby use typical of BIOS and clock circuits, minimizing self-discharge and helping to preserve stored settings during extended power-off periods.

Suitable for

  • Maintaining BIOS/CMOS settings and real-time clock on compatible Lenovo systems
  • Replacing depleted motherboard backup batteries in laptops
  • Replacing depleted motherboard backup batteries in desktop PCs

Key specifications

  • Chemistry: lithium
  • Form factor: coin cell
  • Nominal voltage: 3V
  • Capacity: 220mAh
  • Intended use: CMOS/BIOS backup and real-time clock retention

How to use

Power off the system and disconnect it from mains power before replacing the CMOS battery. Open the device chassis or access panel to locate the existing coin cell on the motherboard. Remove the old battery from its holder, noting polarity and orientation, and insert the new coin cell with the correct polarity to ensure proper contact. Reassemble the device and restore power. After replacement, check BIOS settings and system clock and reconfigure if necessary.

Usage recommendations

Use this battery only in devices that specify a 3V lithium coin cell with similar capacity and form factor. Dispose of the old battery according to local battery recycling regulations. If BIOS settings reset persist after replacement, consult the device manual or technical support to verify compatibility and correct installation.
