Frequently asked questions
How can I confirm that this C21N1401 battery is the correct one for my Asus laptop?
The safest way is to remove your current battery and check the part number printed on it. If it matches C21N1401 or any of the listed compatible part numbers, it is the correct one. You can also check if your laptop model (e.g., X455LA) is on our list of compatible models. If you have any doubts, contact our technical support.
Is it necessary to calibrate the new battery upon installation?
Yes, it is highly recommended. To calibrate it, charge it to 100%, then use the laptop until it turns off due to low battery (5-10%), and finally recharge it to 100% without interruptions. This helps the system recognize the battery's actual capacity and optimizes its long-term performance.
How many hours of autonomy can I expect from this battery?
Autonomy depends on laptop usage, screen brightness, and running applications. This 4775mAh battery is designed to restore the original autonomy your device had when it was new. We cannot provide an exact figure in hours, but it will recover the portability lost due to the wear of the old battery.
