Frequently asked questions
Is it necessary to calibrate the new battery the first time it is used?
Yes, an initial calibration cycle is recommended. Charge the battery to 100% with the laptop turned off. Then, turn it on and use it on battery power until it is completely discharged and the device shuts down. Finally, charge it back to 100% without interruptions. This process helps the system recognize the new battery's actual capacity and display the charge percentage accurately.
What warranty does this battery have and what happens if it doesn't work or fit?
We offer a 3-year warranty for private customers and 1 year for professionals. If the battery is not compatible or has any defect, you have 14 days to return it. You can arrange the return shipping yourself or request a home pickup for 8.90 € in Spain and Portugal, which will be deducted from the refund.
