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. Remove the battery from your laptop and look for a label with a code. If it matches HSTNN-Q73C, this battery is the correct one. You can also compare the physical shape and voltage (10.8V or 11.1V) with the images and specifications on this product page.
Is it necessary to calibrate the new battery?
Yes, it is highly recommended. To calibrate it, charge the battery to 100% the first time. Then, use it until the laptop turns off due to low battery (approximately at 5%). Finally, charge it back to 100% without interruptions. This process helps the system recognize the actual capacity and optimizes its lifespan.
What battery life can I expect from this battery?
Battery life depends on your laptop's power consumption (CPU usage, screen brightness, etc.) and the original capacity. With 4400 mAh, this battery aims to match or exceed the duration of the original battery when it was new. Generally, you can expect between 2 and 4 hours of moderate use, but this is an estimate.
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 (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 yourself or request a home collection for 8.90 € in Spain and Portugal, which will be deducted from the refund.
