Always check the part number printed on your original part before ordering; if in doubt, contact us with the exact model of your device.
To ensure compatibility, check the part number on your original battery. If it matches HSTNN-W99C, FP06, H6L26AA, or any of the other part numbers listed on our product page, it is the correct one. You can also verify if your laptop model is one of the HP ProBook 440, 450, 455, or 470 series from the G0 or G1 generations.
Yes, it is recommended to perform an initial calibration cycle. Charge the battery to 100%, let it rest for an hour, then use it until the laptop shuts down due to low battery (approx. 5%). Finally, charge it back to 100% without interruptions. This helps the system recognize the actual capacity and optimizes its performance.
Autonomy depends on laptop usage, screen brightness, and running applications. With 4400 mAh, you can expect a duration similar to that of the original battery when it was new, typically between 2 and 4 hours for standard office use. Your equipment's power consumption is the determining factor.
The battery has a 3-year warranty for private customers and 1 year for businesses. Additionally, you have 14 days to return it if you are not satisfied. You can manage the return shipping yourself or request a home pickup for 8.90 € in Spain and Portugal, which will be deducted from the refund.
