Frequently asked questions
How do I know if this RU586 battery is compatible with my Dell laptop?
The safest way is to remove your current battery and check the part number printed on it. If it matches RU586, GW240, RN873 or any of the others in the compatibility list, it will work. You can also check if your laptop model, such as Inspiron 1525 or 1545, appears in our list of compatible models.
Do I need to calibrate the new battery the first time I use it?
Yes, an initial calibration cycle is recommended. Charge the battery to 100%, then use it continuously until the laptop warns of low battery (approximately 5-10%) and shuts down. Finally, recharge it to 100% without interruptions. 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 varies depending on laptop usage, screen brightness, and running applications. With a capacity of 4400 mAh (49 Wh), you can expect a duration similar to that of the original battery when it was new, which is usually between 2 and 4 hours for office use or web browsing.
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 and 1 year for professionals. If upon receipt it is not compatible or has any defect, you have 14 days to return it. You can manage the return shipping on your own or request a home pickup for 8,90 € in Spain and Portugal, which will be deducted from the refund.
