Frequently asked questions
Is it necessary to calibrate the 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 with the battery until it is completely depleted and the device turns off. Finally, recharge it to 100% without interruptions. This process helps the system recognize the actual capacity of the new battery and accurately display the charge percentage.
How many hours of autonomy can I expect from this battery?
Autonomy depends on your laptop's consumption (processor usage, screen brightness, etc.) and the capacity of the original battery. This 4400 mAh battery is designed to match or exceed the autonomy of the original battery when it was new. Generally, you can expect between 2 and 4 hours of moderate use, but this value is indicative.
What warranty does it have and what do I do if it doesn't work or doesn't fit my laptop?
We offer a 3-year warranty for private customers (1 year for professionals). If the battery is not compatible or has any defect, you have 14 days to return it. You can manage the return shipping on your own or request a home pickup for 8.90 € in Spain and Portugal, which will be deducted from the refund. Please contact our customer service to start the process.
