Frequently asked questions
Is it necessary to calibrate the battery the first time I use it?
Yes, it is highly recommended. To calibrate the new battery, charge it completely to 100% with the laptop turned off. Then, turn it on and use it on battery until it is completely depleted and the device shuts down. Finally, recharge it to 100% without interruptions. This process helps the system recognize the battery's actual capacity and optimizes its lifespan.
How many hours of approximate autonomy does this battery offer?
Actual autonomy depends on the exact laptop model, its usage (browsing, video, office work), and power settings. A 2200 mAh battery like this typically offers between 1.5 and 3 hours of moderate use, aiming to restore autonomy similar to what the original battery offered when new.
What warranty does it have and what should I do if it doesn't work or doesn't fit my laptop?
The battery has a 3-year warranty for private customers (1 year for professionals). If upon receipt it is not compatible or has any defect, you have 14 days to return it. You can arrange the return shipment yourself or request a home pickup for 8.90 € in Spain and Portugal, which will be deducted from the refund. Contact our customer service to start the process.
