Frequently asked questions
How can I be sure that this QK643AA battery is compatible with my HP laptop?
The most reliable way is to compare the part number. Remove your current battery and look for a label with a code. If it matches QK643AA, this battery is the correct one. You can also compare the physical shape and voltage (10.8V/11.1V). If you have doubts, contact our technical support with the exact model of your laptop.
Is it necessary to calibrate the new battery the first time it is used?
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 with the battery until it is completely depleted and the device shuts down. Finally, recharge it to 100% without interruptions. This process helps the system recognize the battery's actual capacity.
