Frequently asked questions
Do I need to calibrate the new battery the first time I use it?
Yes, it is highly recommended. To calibrate it, charge the battery to 100%, then use it until the laptop shuts down due to low battery (or reaches 5%). Finally, recharge it to 100% uninterruptedly. This process helps the operating system recognize the battery's actual capacity.
What warranty does it have and what do I do if it doesn't work or doesn't 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 send it on your own or request a home collection for 8.90 € in Spain and Portugal, which will be deducted from the refund.
How long does it take to arrive if I order it today?
Orders are prepared on the same day if placed before 16:00 (15:00 on Fridays). Shipping to Spain and Portugal takes between 24 and 48 working hours. For other European Union destinations, the usual delivery time is 2 to 5 working days.
