Frequently asked questions
Do I need to calibrate the battery the first time I use it?
Yes, it is highly recommended. To calibrate it, charge it to 100%, then use the laptop until the battery discharges to 10-15%, and finally, fully recharge it without interruptions. This process helps the operating system recognize the new battery's actual maximum capacity.
How long will this battery's charge last?
Battery life depends on your laptop's power consumption and your usage (screen brightness, running programs, etc.). With 49 Wh of energy, this battery offers a duration similar to that of your original equipment's battery when it was new, restoring its portability.
What warranty does it have and what do I do if it doesn't fit or doesn't work?
The battery has a 3-year warranty for private customers and 1 year for professionals. If upon receipt it does not fit or does not work correctly, you have 14 days to return it. You can manage the return shipment on your own or request home collection for 8,90 € in Spain and Portugal.
When will I receive the battery if I order it today?
Orders are prepared the same day if placed before 16:00 (15:00 on Fridays). For Spain and Portugal, shipping takes 24-48 business hours. For France, it's 2-3 days, and for the rest of the EU, between 2 and 5 business days.
