Frequently asked questions
How do I know if this battery is compatible with my HP laptop?
The safest way is to compare the part number of your original battery. Disassemble the battery and look for a label with codes such as NP03XL, 760944-421, or HSTNN-LB6L. If it matches any on our product page list, it is compatible. You can also check if your laptop model, such as an HP Envy x360 15-U, is on the list of compatible models.
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 device turns off. Finally, recharge it to 100% without interruptions. This cycle helps the system recognize the actual capacity of the new battery.
What warranty does it have and what do I do 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 is not compatible or does not work, you have 14 days to return it. You can manage the return yourself or request a home collection for 8.90 € in Spain and Portugal, which will be deducted from the refund.
How long does the autonomy last with this battery?
Autonomy depends on laptop usage, screen brightness, and running applications. With a capacity of 3750 mAh (43 Wh), you can expect a duration similar to that of the original battery when it was new. For office and browsing use, it should provide several hours of work without needing to be connected to power.
Is the 11.4V voltage compatible if my original battery says 10.8V?
Yes, it is compatible. Lithium batteries have a working voltage range. The values of 10.8V and 11.4V are nominal and are considered equivalent for this type of battery. The laptop's charging system is designed to manage these small variations without any problem.
