How to use

Power down the laptop and disconnect the mains adapter before replacing the battery.

Use the replacement battery with the original or approved Dell power adapter and avoid exposure to extreme temperatures or moisture. Charge and store the battery in a cool, dry place and perform occasional full charge/discharge cycles to help maintain accurate capacity reporting. If the battery shows swelling, overheating, or abnormal behavior, discontinue use and follow proper electronic waste disposal procedures.
