## Long description

Battery HP L02772-001 RTC 3V 220mAh is a lithium coin cell intended as a backup power source for real-time clock (RTC) and CMOS memory in compatible HP equipment. With a nominal voltage of 3V and a 220mAh capacity, this small-format battery provides a stable supply to preserve system settings, time and date when main power is removed. It is suitable for maintenance, repair or replacement tasks on HP motherboards and server hardware that require a dedicated RTC backup cell.
Advantages
The lithium chemistry delivers consistent voltage over its service life and long shelf stability, reducing the risk of configuration loss. Its coin-cell form factor fits standard RTC battery holders used in many HP systems. The 220mAh capacity offers extended backup time compared with lower-capacity cells, and the nominal 3V rating matches common CMOS/RTC circuits for reliable operation.
Suitable for
Restoring RTC and BIOS settings on HP motherboards
Replacing depleted backup cells in servers and workstations
Preventive maintenance of timekeeping and configuration retention
Repair projects that require a compatible 3V coin cell
Key specifications
Chemistry: lithium
Form factor: coin cell
Nominal voltage: 3 V
Capacity: 220 mAh
Primary (non-rechargeable) cell intended for backup use
Designed for low-drain, long-term standby applications such as RTC/CMOS backup
How to use
Power the device down and disconnect it from mains supply before replacing the battery. Locate the RTC coin cell holder on the motherboard or device PCB, gently remove the depleted cell using non-conductive tools if necessary, and insert the replacement with the correct polarity. Reconnect power and verify that the system clock and BIOS settings are retained. Dispose of the removed battery according to local regulations for lithium cells.
Usage recommendations
Store unused batteries in a cool, dry place away from direct sunlight and conductive materials. When installing, avoid shorting the terminals and handle the cell with clean, dry hands or suitable tools. Replace the backup cell promptly if system time resets or CMOS settings are lost to prevent configuration issues.
