Frequently asked questions
Is it necessary to calibrate the battery the first time?
Yes, it is highly recommended. After installing it, charge the battery to 100% and leave it connected for 2 more hours. Then, use the laptop on battery until it is completely depleted and turns off. Finally, perform a full charge to 100% without interruptions. This process helps the operating system measure the real capacity and optimizes its lifespan.
How many hours of autonomy does this battery provide?
The actual autonomy depends on your laptop's power consumption, which varies according to usage (screen brightness, programs, connectivity). With a capacity of 3400 mAh, this battery is designed to match or improve the autonomy your device had when it was new, allowing you to recover mobility lost due to wear.
What warranty does it have and how can I return it if it's not the correct one?
We offer a 3-year warranty for private customers and 1 year for professionals. If the battery is not compatible or you are not satisfied, you have 14 days to return it. You can send it on your own or request a home collection for 8,90 € in Spain and Portugal, an amount that will be deducted from the refund.
