## Summary description

Replacement CR2032 3V coin cell battery compatible with Lenovo RTC/CMOS applications, model FRU04Y1784. Designed to preserve system time and BIOS settings when the main power is disconnected. Suitable for service, repair and maintenance of Lenovo laptops and motherboards that use a CR2032 RTC battery, offering long shelf life and stable voltage for reliable timekeeping.

## Long description

Replacement CR2032 3V coin cell battery designed for Lenovo RTC/CMOS applications. This battery provides a stable 3V output to maintain system time, BIOS settings and CMOS memory when the main power is removed. It is intended as a direct substitute for standard CR2032 cells used in many Lenovo laptops and compatible motherboards, offering long shelf life and consistent voltage under typical RTC loads.
Advantages
The CR2032 3V battery delivers stable nominal voltage and low self-discharge for extended shelf life and reliable timekeeping. Its standard coin-cell form factor makes installation straightforward in supported RTC/CMOS holders. The battery's chemistry offers consistent performance across typical operating temperatures encountered in laptop and desktop chassis, supporting accurate BIOS/clock retention during power-off periods.
Suitable for
Replacing depleted RTC/CMOS batteries in Lenovo laptops and compatible motherboards
Service and repair tasks where maintaining BIOS settings and system clock is required
Maintenance of small electronics that accept a CR2032 coin cell for backup power
Key specifications
Cell type: CR2032 lithium coin cell
Nominal voltage: 3 V
Typical capacity: around 200–240 mAh (varies by manufacturer)
Form factor: 20 mm diameter, 3.2 mm thickness (standard CR2032 size)
Chemistry: lithium manganese dioxide (Li-MnO2)
Operating temperature: suitable for typical laptop and motherboard ambient ranges
How to use
Power down the device and disconnect mains power and battery packs before replacing the RTC/CMOS cell. Access the RTC holder on the motherboard or laptop service area following the device manufacturer’s disassembly instructions. Remove the old CR2032 cell from its holder, noting polarity, and insert the replacement with the correct orientation so the positive (+) side faces the designated contact. Reassemble the device and reconnect power, then verify system time and BIOS settings in the firmware interface and adjust if necessary.
Usage recommendations
Store unused batteries in a cool, dry place away from direct sunlight and metal objects. Replace the RTC/CMOS battery promptly when system time resets or BIOS settings are lost. Dispose of used lithium coin cells according to local regulations for battery recycling and hazardous waste.
