Frequently asked questions
How can I be sure that this C21N1634 battery is the correct one for my Asus laptop?
To confirm compatibility, the most reliable way is to check your laptop's original battery. Look for the part number printed on the label; if it matches C21N1634, this is the correct part. You can also check if your laptop model, such as a VivoBook X542UA or F542UQ, appears in our list of compatible models. Comparing the shape and connector with the product photos is a good final check.
Is it necessary to calibrate the battery the first time I use it?
Yes, for optimal performance, an initial calibration cycle is recommended. Once installed, charge the battery to 100% without interruption. Then, use the laptop on battery power until it completely discharges and turns off by itself. Finally, charge it back to 100% without using the device. This process helps the system recognize the new battery's actual capacity.
What warranty does it have and what do I do if it's not compatible or doesn't work?
We offer a 3-year warranty for private customers (1 year for professionals). If the battery is not compatible or has any defect, you have 14 days to return it. You can arrange the return shipping yourself or request a home pickup for 8.90 € in Spain and Portugal, which will be deducted from the refund. Our technical team is available to assist you.
