Frequently asked questions
How do I know if this MU09 battery is compatible with my laptop?
The safest way is to compare the part number (P/N) of your original battery. Remove the battery from your laptop and look for a label with a code. If it matches 'MU09', it is the correct one. Since this reference may be compatible with several models, if you have doubts, contact us with the exact make and model of your laptop to confirm.
Do I need to calibrate the battery the first time I use it?
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, charge it back to 100% without interruptions. This process helps the system recognize the actual capacity of the new battery.
How many hours of autonomy can I expect from this battery?
Autonomy depends on your laptop's consumption (processor usage, screen brightness, etc.) and the capacity of the original battery. This 4400 mAh battery aims to match or exceed the duration of the original part when it was new. Generally, you can expect between 2 and 4 hours of moderate use.
What warranty does it have and what do I do if it doesn't work or fit?
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 collection for 8.90 € in Spain and Portugal, which will be deducted from the refund.
