Frequently asked questions
Is it necessary to calibrate the new battery the first time?
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 normally until it completely discharges and the device turns off by itself. Finally, charge it back to 100% without interruptions. This process helps the system recognize the battery's real capacity and optimizes its lifespan.
What autonomy can I expect from this battery?
The actual autonomy depends on your laptop usage, screen brightness, and running applications. With a capacity of 49 Wh, this battery is designed to offer a duration similar to the original when it was new. Light office or web browsing use will provide several hours of autonomy.
What warranty does it have and how does the return process work?
The battery has a 3-year warranty for private customers and 1 year for professionals. If you are not satisfied or it is not compatible, you have 14 days to return it. The return shipping is at your expense, or we can arrange a home collection for 8.90 € in Spain and Portugal, which will be deducted from the refund amount.
