Frequently asked questions
Do I need to calibrate the new battery the first time I use it?
Yes, it is recommended. To do this, charge the battery to 100% with the laptop turned off. Then, use it on battery power until it runs out and the device shuts down on its own. Finally, charge it back to 100% without interruptions. This process helps the system recognize the actual capacity of the new battery.
How many hours of autonomy can I expect from this battery?
Autonomy depends on usage, screen brightness, and running applications. With a capacity of 3900mAh (44Wh), you can expect a duration similar to that of the original battery when it was new, typically between 2 and 4 hours for standard office use.
What warranty does it have and what do I do if it doesn't work or fit?
The battery has a 3-year warranty for private individuals (1 year for professionals). If it is not compatible or has any defect, you have 14 days to return it. You can send it on your own or request a home pickup for 8,90 € in Spain and Portugal, the cost of which will be deducted from the refund.
