## Summary description

Lithium coin cell CMOS battery Lenovo CR2016, compatible with part number 5B11C73716, designed to power the motherboard real-time clock (RTC) and preserve BIOS settings when the main power is off. Compact CR2016 form factor provides reliable low-current backup for laptops and desktops. Easy to install replacement to restore system timekeeping and BIOS configuration.

## Long description

Lenovo CMOS battery CR2016 is a lithium coin cell designed to provide long-term low-current backup to a computer motherboard's real-time clock (RTC) and preserve BIOS/UEFI settings when the main power is disconnected. The CR2016 form factor is compact and compatible with many laptop and desktop systems that require a 3V coin cell for RTC and CMOS memory retention. This replacement coin cell restores system timekeeping, retains configuration data and helps prevent boot errors related to lost BIOS settings.
Advantages
The CMOS battery offers stable 3V output and low self-discharge, ensuring reliable retention of motherboard settings over extended periods without external power. Its compact CR2016 size makes it suitable for tight battery compartments on modern laptops and small-form-factor motherboards. As a drop-in replacement for compatible RTC coin cells, it enables simple, cost-effective maintenance and minimizes the risk of CMOS-related system errors.
Suitable for
 Replacing depleted RTC/CMOS battery in laptops
 Maintaining BIOS/UEFI settings on desktops and small-form-factor PCs
 Restoring system clock and preventing date/time related errors
 Use in embedded systems and motherboards requiring a CR2016 3V coin cell
Key specifications
 Chemistry: Lithium manganese dioxide (Li-MnO2)
 Nominal voltage: 3 V
 Cell type: Coin cell (CR2016 form factor)
 Typical capacity: low mAh range suitable for RTC backup
 Operating temperature: typical commercial range for motherboard batteries
 Physical dimensions: nominal diameter ~20 mm, thickness ~1.6 mm
How to use
Power down the computer and disconnect it from mains power. If present, remove the internal battery and ground yourself to avoid electrostatic discharge. Locate the motherboard coin cell holder, gently release the retaining clip and remove the old battery, noting its polarity. Insert the CR2016 replacement with the correct orientation so the positive side faces outward as indicated on the holder. Re-secure the retaining clip, reconnect power and start the system. Enter BIOS/UEFI to confirm saved settings and update the system time if necessary.
Usage recommendations
Store spare CMOS batteries in a cool, dry place and handle them with clean, dry hands. Replace the coin cell promptly when system time resets, BIOS settings are lost, or the device displays CMOS-related error messages. Dispose of used lithium coin cells according to local battery recycling regulations.
