Frequently asked questions
How can I be sure this battery is compatible with my HP laptop?
The most reliable way is to check the part number (P/N) of your original battery. Remove the battery from your laptop and look for a label with a code similar to 718675-421. If the code matches, this battery is the correct one. The laptop model can be misleading, as the same series may use different batteries. Checking the part number is the guarantee of compatibility.
Is it necessary to calibrate the new battery the first time I use it?
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 the battery is completely discharged and the device turns off by itself. Finally, recharge it to 100% without interruptions. This initial cycle helps the system recognize the battery's actual capacity and optimizes its performance and lifespan.
What autonomy can I expect with this 4400 mAh battery?
Autonomy depends on your laptop's consumption (screen brightness, CPU usage, etc.) and the age of the device. A new 4400 mAh battery should provide a duration similar to that of the original battery when it was new, typically between 2 and 4 hours for standard office use. It is a standard capacity to restore the original functionality of the device.
What warranty does it have and what do I do if it doesn't work or doesn't fit my laptop?
The battery has a 3-year warranty for private individuals (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. It is important to verify compatibility before purchasing.
