Frequently asked questions
How do I know if this battery is compatible with my Asus laptop?
The safest way is to check the part number of your original battery. Remove the bottom cover of your laptop and look for a label on the battery. If the code is C31N1339 or one of the equivalent ones listed, this battery is correct. It is also compatible if your equipment belongs to the ZenBook UX303, TP300, or Q302 series.
Is it necessary to calibrate the new battery the first time?
Yes, it is highly recommended. To calibrate it, charge the battery to 100% with the laptop turned off. Then, turn it on and use it normally until it is completely depleted and the equipment turns off. Finally, recharge it to 100% without interruptions. This process helps the system recognize the battery's actual capacity.
What autonomy can I expect from this battery?
Autonomy depends on laptop usage, screen brightness, and running applications. With a capacity of 3625 mAh (41 Wh), you can expect a duration similar to that of the original battery when it was new, typically between 3 and 5 hours for standard office and browsing use.
What warranty does it have and what do I do if it doesn't work or doesn't fit?
The battery has a 3-year warranty for private customers (1 year for professionals). If upon receipt it does not fit or does not work, you have 14 days to return it. You can manage the return on your own or request a home pickup for 8.90 € in Spain and Portugal, which will be deducted from the refund.
