Frequently asked questions

How do I know if this A31N1519 battery is the correct one for my Asus laptop?

The safest way is to check the label on your original battery. Turn off the laptop, remove it, and look for the part number. If it matches A31N1519, this battery is 100% compatible. You can also check if your laptop model, such as an Asus X540SA, is on our list of compatible models.

Is it necessary to calibrate the battery the first time I use it?

Yes, it is highly recommended. To calibrate it, install the new battery, charge it to 100% without interruption, then use the laptop until it fully discharges and turns off by itself. Finally, charge it back to 100% without using the device. This process helps the operating system display the charge level accurately.

What autonomy can I expect from this battery?

Battery life depends on your laptop's consumption (screen brightness, CPU usage, etc.) and the original capacity of the battery it replaces. This battery is designed to offer performance equivalent to the original part when it was new. With moderate use, you can expect several hours of work without needing to be connected to power.

What warranty does it have and how does the return work if it's not compatible?

The battery has a 3-year warranty for individuals and 1 year for professionals. If upon receiving it you find that it is not compatible, you have 14 days to return it. You can arrange the return shipment on your own or request a home pickup for 8,90 € in Spain and Portugal, which will be deducted from the refund.
