Frequently asked questions
How can I be sure that this C31N1821 battery is the correct one for my Asus laptop?
To confirm compatibility, the most reliable way is to verify the part number of your original battery. Remove the bottom cover of your laptop and look for the label. If the printed code is 'C31N1821' or '0B200-03210100', this battery is correct. You can also confirm that your laptop model is one of those listed: ZenBook S13 UX392, UX392FA, or UX392FN.
Is it necessary to calibrate the new battery the first time it is used?
Yes, an initial calibration cycle is recommended. Charge the battery to 100% with the laptop turned off. Then, turn it on and use it on battery power until it completely discharges and the device shuts down. Finally, recharge it to 100% without interruptions. This process helps the system recognize the new battery's actual capacity and display the charge percentage accurately.
