Frequently asked questions
Is it necessary to calibrate the new 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 on battery until it is completely depleted 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 correctly.
How many hours of autonomy can I expect from this battery?
Actual autonomy depends on many factors, such as screen brightness, processor usage, and running programs. With a capacity of 4100 mAh, you can expect a duration similar to that of the original battery when it was new. Generally, this translates to several hours of office use or web browsing.
What warranty does it have and what do I do if it doesn't work or isn't the correct one?
The battery has a 3-year warranty for private customers (1 year for professionals). If upon receipt it is not compatible or has any defect, you have 14 days to return it. You can manage the return yourself or request a home collection for 8,90 € in Spain and Portugal, which will be deducted from the refund.
