Frequently asked questions
How do I know if this NP03 battery is compatible with my HP laptop?
To ensure compatibility, check the part number printed on your original battery. If it matches NP03 or any of the equivalents listed such as NP03XL, 760944-421, or HSTNN-LB6L, this battery is correct. You can also verify if your laptop model, such as the HP Envy x360 15-U, is on the list of compatible models. The voltage (11.4V) must also be similar.
Is it necessary to calibrate the new battery the first time?
Yes, it is recommended. To calibrate it, charge the battery to 100% with the laptop turned off. Then, turn it on and use it with the battery until it is completely depleted and the device turns off. Finally, recharge it to 100% without interruptions. This process helps the operating system display the charge level accurately.
What is the battery warranty and what happens if it doesn't work or fit?
The battery has a 3-year warranty for private customers and 1 year for professionals. If upon receipt it does not fit or does not work correctly, you have 14 days to return it. You can manage the return shipping on your own or request a home pickup for 8.90 € in Spain and Portugal, which will be deducted from the refund.
