How to use

Before installation, power down the laptop and disconnect any external power source. Remove the existing battery following the notebook manufacturer's procedure, taking care to avoid static discharge. Align the replacement battery with the battery bay and connector, then seat it firmly until it clicks or locks in place. After installation, connect the mains adapter and allow the battery to charge fully before first use to ensure the battery management system recalibrates. Use the operating system's battery status tools to confirm proper recognition and charging behavior.

Recommendations

Store the battery in a cool, dry place if not used for extended periods and avoid exposure to temperatures above 60°C or below -20°C. For optimal long-term performance, avoid keeping the battery at full charge or fully discharged for prolonged periods; moderate charge levels (around 40–60%) are preferable during long-term storage. Dispose of the battery according to local electronic waste regulations; do not incinerate or puncture the pack.
