Frequently asked questions
How can I tell if this MU09XL battery is compatible with my laptop?
To ensure compatibility, the most reliable way is to check your laptop's original battery. Look for the reference printed on the label; if it matches MU09XL, this battery is the correct one. It is also important to compare the voltage (10.8V/11.1V) and the physical shape of the battery with the product images to guarantee a perfect fit in your equipment's compartment.
Do I need to calibrate the new battery the first time I use it?
Yes, it is highly recommended. To calibrate the MU09XL battery, charge it completely to 100% the first time. Then, use the laptop on battery until it is fully discharged and the device turns off. Finally, charge it back to 100% without interruptions. This process helps the system recognize the battery's real capacity and optimizes its performance.
How much approximate autonomy does this battery offer?
The autonomy of a 4400 mAh battery depends on your laptop's power consumption, which varies depending on usage (browsing, video, games) and power settings. On average, you can expect between 2 and 4 hours of autonomy, but this value is indicative. A powerful processor or a screen with high brightness will reduce the duration.
What warranty does it have and what do 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 does not fit or does not work, you have 14 days to return it. You can manage the return yourself or request home collection for 8.90 € (in Spain and Portugal), which will be deducted from the refund. It is crucial to verify compatibility before purchasing.
