Frequently asked questions
How can I be sure that this B31N1912 battery is compatible with my ASUS laptop?
To confirm compatibility, the most important thing is to verify the part number of your original battery. Disassemble your laptop's casing and look for a label on the battery. If the code is B31N1912, this is the correct part. Additionally, compare the connector (it must be 7-pin) and the physical shape with our product images. This battery is compatible with models such as the ASUS E410MA, E510KA, and L410MA.
Do I need to calibrate the new battery after installing it?
Yes, for optimal performance and accurate charge level reading, we recommend an initial calibration. After installation, charge the battery to 100% without interruption. Then, use the laptop until it is completely depleted and shuts down on its own. Finally, charge it back to 100% without using the device. This cycle helps synchronize the battery with the system.
What autonomy can I expect from this battery?
Autonomy depends on laptop usage (screen brightness, running programs, connectivity). With 42Wh capacity, this battery is designed to offer a duration similar to that of the original battery when the laptop was new. You can expect several hours of office use or web browsing on a full charge.
What warranty does it have and what do I do if it doesn't work or isn't the correct one?
The battery has a 3-year warranty for private customers and 1 year for professionals. If upon receipt it is not compatible or has any defect, you have 14 days to return it. You can manage the return shipment on your own or request a home collection for 8.90 € in Spain and Portugal, which will be deducted from the refund.
