Frequently asked questions
How can I be sure that this 917724-855 battery is compatible with my HP laptop?
To confirm compatibility, you must remove the original battery from your laptop and verify that the part number printed on it matches 917724-855. Even if your laptop model is compatible, manufacturers sometimes use different batteries in the same series. Comparing the part number is the safest method.
Is it necessary to calibrate the new battery the first time I use it?
Yes, it is highly recommended. To calibrate it, charge it to 100%, leave it connected for 2 more hours, then use it until the laptop shuts down due to low battery (5-10%), and finally, charge it again to 100% without interruptions. This synchronizes the battery meter with its actual capacity.
How many hours of autonomy can I expect from this battery?
Autonomy depends on your laptop's consumption (screen brightness, CPU usage, etc.) and the device's condition. This 3500 mAh battery offers a capacity similar to the original when it was new. You can expect several hours of moderate use, but we cannot guarantee an exact figure in hours.
What warranty does it have and what do I do if it doesn't work or isn't the correct one?
The battery has a 3-year warranty for private customers and 1 year for professionals. If it is not compatible or has any defect, 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.
