## Summary description

IBM 02K7078 CR2032 is a 3V lithium coin cell battery designed for real-time clock (RTC) backup in compatible IBM and third-party devices. It provides long-term, low-drain power to preserve system time and BIOS settings when the main power is removed. Suitable for servers, desktops, motherboards and embedded systems that use a CR2032 RTC battery.

## Long description

IBM 02K7078 CR2032 is a 3V lithium coin cell battery designed to provide reliable low-drain power for real-time clock (RTC) backup and BIOS parameter retention in compatible IBM and third-party devices. The battery's standardized CR2032 size and nominal 3V output make it suitable for maintaining system time and basic settings when the main power source is removed. It is intended for use in servers, desktops, motherboards and a range of embedded systems that accept CR2032 RTC cells.
Advantages
The IBM CR2032 battery delivers a steady nominal voltage of 3V with low self-discharge characteristics, ensuring long shelf life and extended time between replacements in low-drain RTC applications. Its coin cell form factor provides simple, space-efficient installation in standard CR2032 holders on motherboards and devices. The chemistry and construction are optimized for stable voltage under light continuous loads typical of clock and CMOS memory circuits.
Suitable for
 RTC backup on motherboards in servers and desktops
 BIOS/CMOS setting retention in PC systems
 Embedded systems and industrial controllers that use CR2032 cells
 Small electronics requiring a 3V coin cell with long shelf life
Key specifications
 Cell type: Lithium manganese dioxide (CR2032 pattern)
 Nominal voltage: 3 V
 Diameter: 20 mm (typical for CR2032 cells)
 Thickness: 3.2 mm (typical for CR2032 cells)
 Operating temperature range: suitable for typical indoor electronics environments
 Low self-discharge for long storage life
How to use
Install the coin cell into the device's designated CR2032 holder with the correct polarity: flat side marked with the voltage/label typically faces up and the contact spring or pad connects to the negative side. Ensure the device is powered off and follow anti-static precautions if working on an exposed motherboard or electronic board. After installation, verify that system time and BIOS settings are retained by checking the RTC and BIOS configuration during boot.
Usage recommendations
Store unused batteries in a cool, dry place away from direct sunlight and heat sources. Replace the battery when the system indicates low battery for RTC/BIOS or when timekeeping becomes inaccurate. Dispose of used lithium coin cells according to local battery recycling and hazardous waste regulations.
