Frequently asked questions
How can I be sure this battery is the correct one for my HP laptop?
The most reliable way is to turn off your laptop, remove the battery, and look for the part number printed on it. Compare that code with our 'Compatible Part Numbers' list. If your code, such as CP03XL or HSTNN-LB8E, is on the list, this 929066-421 battery is the correct one.
Is it necessary to calibrate the battery the first time I use it?
Yes, for optimal performance, we recommend an initial calibration cycle. After installing it, charge the battery to 100% without interruptions. Then, use the laptop until it fully discharges and turns off. Finally, charge it back to 100%. This helps the operating system recognize the actual capacity.
What warranty does it have and what do I do if it doesn't fit or doesn't work?
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 send it on your own or request a home collection for 8.90 € in Spain and Portugal, which will be deducted from the refund.
