How to use
Power down the device, disconnect external power and remove any battery or power cables as required by the device manufacturer. Locate the coin-cell holder on the system board, carefully release the old cell from the spring or clip, and observe polarity before inserting the new Dell XXHK0 3V lithium coin cell. Ensure the positive (+) side faces the correct orientation in the holder, seat the cell fully, and restore power. After replacement, verify system time and BIOS/UEFI settings and adjust if necessary.
Usage recommendations
Store unused cells in a cool, dry place away from direct sunlight and heat sources. Do not attempt to recharge, short-circuit, puncture, or expose the battery to fire. Dispose of used batteries according to local regulations for battery recycling or hazardous waste. When replacing the cell on a system board, follow electrostatic discharge (ESD) precautions and refer to the device service manual for model-specific instructions.
