Battery RTC BAT CR2016 Lenovo 30mm 2‑pin

RTC BAT CR2016 Lenovo 30mm 2‑pin is a replacement backup battery designed to provide standby power for real-time clock (RTC) and CMOS memory in compatible Lenovo devices. The CR2016 form factor with a compact 30 mm length and an integrated 2‑pin connector offers a direct fit for systems that require a small-profile coin cell with a detachable connector. This module maintains BIOS timekeeping and configuration settings when the main power source is removed.

Advantages

The battery module combines the familiar CR2016 chemistry and size with a two-pin connector for straightforward motherboard connection, allowing for simple replacement without soldering in many systems. Its compact construction supports installation in tight spaces on notebook and desktop motherboards. The design provides stable long-term standby voltage suited for RTC and CMOS retention tasks, reducing the risk of lost settings or incorrect system time after power loss.

Suitable for

• Motherboard RTC and CMOS backup in compatible Lenovo laptops and desktops
• BIOS configuration and system time retention during power outages or battery removal
• Repair or maintenance tasks that require replacing depleted motherboard backup batteries
• Service environments where a compact, connectorized coin cell is preferred for quick replacement

Key specifications

• Cell type: CR2016 lithium coin cell format
• Overall length: 30 mm (module length including connector)
• Connector: 2‑pin plug for motherboard header connection
• Primary function: RTC and CMOS backup power
• Mounting: inline connector suitable for tight motherboard placements

How to use

Power down the device and disconnect it from mains and external power sources before attempting replacement. Locate the existing motherboard backup battery and carefully disconnect the two‑pin connector. Remove the old module from its holder or cable, then connect the new RTC BAT CR2016 Lenovo 30mm 2‑pin by aligning the connector with the motherboard header and pressing gently until seated. Reassemble any covers or components removed for access and restore power to verify that system time and BIOS settings are retained.

Recommendations

Store unused batteries at room temperature in a dry environment and avoid exposure to high heat or direct sunlight. Dispose of depleted batteries according to local regulations for lithium coin cells. If unsure about compatibility, consult the device service manual or a qualified technician to confirm connector pinout and mounting before installation.
