• Secure and restore power: Reattach any back panels or covers you removed. Reconnect the charger and power on the notebook to confirm proper boot and operation. If the device does not recognize a new battery, consult your notebook’s manual or support for compatibility confirmation.
• Initial charge and care: Allow the battery to reach a full charge before heavy use, and avoid exposing the battery to extreme temperatures during charging. For best results, perform the first charge with the notebook powered down and then gradually reintroduce regular work tasks as the battery settles in.
• Disposal and care: When the battery reaches the end of its life, follow local regulations for battery recycling. Do not puncture or incinerate the battery, and store it in a cool, dry place away from metal objects and moisture when not in use.
