Frequently asked questions
How do I know if this battery is compatible with my HP laptop?
To ensure compatibility, the most important thing is to verify the part number of your original battery. Remove the old battery and look for a label with a code. If the code is 'HSTNN-I91C', this battery is correct. Also compare the voltage (10.8V or 11.1V) and the physical shape with the product images. The laptop model is not sufficient, as the same series can use different batteries.
Is it necessary to calibrate the new battery upon installation?
Yes, an initial calibration cycle is recommended. Once installed, charge the battery to 100% without interruption. Then, use the laptop on battery power until it completely discharges and the device turns off. Finally, recharge it to 100% without using the laptop. This process helps the operating system recognize the battery's actual capacity and display accurate percentages.
What autonomy can I expect from this 4400mAh battery?
Actual autonomy depends on your laptop's power consumption (screen brightness, CPU usage, running programs) and power settings. A 4400mAh battery is a standard capacity that should provide between 2 and 4 hours of moderate use in most compatible devices. This is an estimate, not a guaranteed value, as it varies greatly with each laptop and usage.
What is the warranty and how do returns work if it's not compatible?

Additionally, you have 14 days to return the product if it is not compatible or if you simply change your mind.
