Frequently asked questions
Is it necessary to calibrate the battery the first time it is used?
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 with the battery until it is completely depleted and the device turns off. Finally, recharge it to 100% without interruptions. This process helps the operating system recognize the actual capacity of the new battery and display the charge percentage accurately.
What warranty does it have and what do I do if it doesn't work or 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 manage the return on your own or request a home collection for 8,90 € in Spain and Portugal, which will be deducted from the refund. Please contact our customer service to start the process.
How long does the battery last approximately?
Battery life depends on the laptop model, its power configuration, and its usage (browsing, video, gaming, etc.). With 4400 mAh, you can expect a duration similar to that of the original battery when it was new. To maximize duration, we recommend adjusting screen brightness and configuring your operating system's power plans.
