Battery IBM RTC 92P0986 — Rechargeable 3.6V 2200mAh RTC/CMOS Backup Battery

Replacement IBM RTC battery model 92P0986 is a rechargeable 3.6V 2200mAh backup power source designed to maintain real-time clock (RTC) and CMOS settings in compatible servers and motherboards. The battery supplies stable voltage to retain timekeeping and system configuration when main power is removed, supporting maintenance, repairs, and system refurbishment where an IBM-specified RTC backup is required.

Advantages

This rechargeable 3.6V battery offers high capacity and long shelf life for reliable RTC and CMOS backup. Its rechargeable chemistry reduces the need for frequent replacements and supports multiple discharge/charge cycles when used in systems that provide charging functionality. The compact cylindrical module is engineered for compatibility with server and motherboard RTC battery compartments, providing consistent voltage output and minimizing risk of data loss or clock drift during power outages.

Suitable for

• Maintaining system time and CMOS settings in IBM-compatible servers and motherboards
• Routine maintenance and replacement during repairs or refurbishment
• IT asset lifecycle management where long-term RTC backup is needed
• Laboratories or test benches replacing depleted RTC backup cells

Key specifications

• Nominal voltage: 3.6 V
• Capacity: 2200 mAh
• Rechargeable chemistry suitable for repeated charge/discharge cycles
• Compact cylindrical form factor for in-board RTC/CMOS compartments
• Designed for long-term timekeeping and configuration retention during power loss

How to use

Power down the system and follow the manufacturer’s service instructions for safe access to the RTC/CMOS battery compartment. Remove the depleted battery carefully, observing polarity and any retention clips. Install the replacement battery with correct orientation and secure any fasteners or holders. If the host system provides charging for the RTC battery, power the system to allow the battery to reach normal operating charge. Verify system time and CMOS settings after installation.

Recommendations

Store the battery in a cool, dry place away from direct sunlight and heat sources. Do not short-circuit, disassemble, or expose the battery to fire. When replacing the RTC battery, confirm compatibility with the host motherboard or server documentation. Dispose of depleted cells according to local battery recycling regulations.
