Frequently asked questions
How can I tell if this battery is the correct one for my HP laptop?
The safest way is to remove your current battery and compare the part number printed on it with the list of compatible references on this product page, such as NP03XL, 760944-421, or HSTNN-LB6L. If your number matches, this battery is compatible.
Is it necessary to calibrate the battery the first time it's used?
Yes, it is highly recommended. To calibrate it, charge the battery to 100% with the laptop turned off, then use it normally until it is completely depleted and the device shuts down. Finally, charge it back to 100% without interruptions. This helps the system recognize the battery's true capacity.
How many hours of autonomy can I expect from this battery?
Autonomy depends on laptop usage (screen brightness, running programs, etc.). This 43 Wh battery is designed to restore the original autonomy your device had when it was new. Its duration will be similar to that of the factory battery in its early days.
What warranty does it have and what do I do if it doesn't work or fit?
We offer a 3-year warranty for private customers (1 year for professionals). If the battery is not compatible or has any defect, you have 14 days to return it. You can arrange the return shipment yourself or request a home collection for 8,90 € in Spain and Portugal.
