How to use

Power down the laptop and disconnect any external power source before replacing the battery. Remove the access panel or release the battery latch according to the laptop manufacturer’s instructions, then remove the existing battery and install the replacement battery, ensuring it seats securely and any latches or screws are reinstalled. After installation, connect the AC adapter and charge the battery fully before first regular use to calibrate the battery management system. Use the laptop's power management settings to optimise runtime and battery health.
