Power off and unplug your laptop. Remove the bottom screws, gently disconnect the old battery, and secure the new one. Reassemble and charge fully before first use. Refer to your model’s service manual or an authorised technician for safe installation.
Usage & care tips
Avoid full discharges; keep charge between 20–80% for longevity. Store in a cool, dry place (ideal 15–25°C). Use only Asus-approved chargers. Calibrate monthly by fully charging and discharging once.
