How to use

Power down the laptop and disconnect any external power source.

Reconnect AC power and allow the system to recognize the new battery; the operating system or BIOS may display charging status and battery level. Calibrate the battery if recommended by the laptop manufacturer by fully charging and then fully discharging once or twice. Follow normal charging practices and allow the battery to complete charge cycles occasionally to maintain accurate capacity reporting.

Usage recommendations

Store the battery at moderate temperature and partial charge if not in use for extended periods. Avoid exposure to extreme heat or cold. Use the laptop’s original charger or a manufacturer-approved replacement and keep firmware and power management drivers up to date to ensure safe operation and correct battery reporting.
