Frequently asked questions
Is it necessary to calibrate the battery the first time?
Yes, an initial calibration cycle is recommended. Charge the battery to 100%, let it rest for 2 hours connected, then use the laptop on battery until it turns off or hibernates (around 5%). Let it rest for 5 hours powered off and finally charge it to 100% without interruption. This helps the system recognize the battery's real capacity.
What is the warranty and what do I do if it doesn't work or fit?
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 send it at your own expense or request a home collection for 8.90 € in Spain and Portugal, which will be deducted from the refund.
