Frequently asked questions
How do I know if this UM08A31 battery is compatible with my Acer laptop?
To ensure compatibility, the most reliable way is to remove your current battery and check the part number printed on the label. If it matches UM08A31 or any of the more than 60 part numbers listed on our product page, it is the correct one. You can also check if your laptop model, such as Aspire One A150 or D250, is on the list of compatible devices.
Is it necessary to do anything special the first time I use it?
Yes, we recommend an initial calibration cycle to optimize its performance and lifespan. Charge the new battery to 100%, then use the laptop until it turns off due to low battery. Finally, recharge it to 100% without interruption. This process helps the operating system recognize the battery's actual capacity.
How many hours of autonomy can I expect from this battery?
Actual autonomy depends on your laptop's power consumption (screen brightness, CPU usage, Wi-Fi) and the tasks you perform. With 4400 mAh, this battery is designed to restore or even exceed the original autonomy of the device when it was new. Generally, you can expect several hours of office use or web browsing.
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 (1 year for professionals). If the battery is not compatible or has any defect, you have 14 days to return it. You can arrange the return shipping yourself or request a home pickup for €8.90 in Spain and Portugal, which will be deducted from the refund.
