Frequently asked questions
How do I know if this 451-10478 battery is compatible with my Dell laptop?
The safest way is to check the part number printed on your original battery. If it matches 451-10478 or any of the compatible ones like GW240, RN873, or M911g, it is the correct one. You can also check if your laptop model, such as Inspiron 1525 or 1545, is on the list of compatible models.
Is it necessary to calibrate the battery the first time I use it?
Yes, it is highly recommended. To calibrate it, charge it to 100%, let it rest for an hour connected, then disconnect the charger and use the laptop until the battery drops to 5-10%. Finally, recharge it to 100% without interruptions. This helps the system recognize the real capacity of the new battery.
How many hours of autonomy can I expect from this battery?
The actual autonomy depends on your laptop's power consumption, screen brightness, and the applications you use. A new 4400mAh / 49Wh battery like this typically provides between 2 and 4 hours of moderate use, although this value is always an estimate.
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 collection for 8.90 € in Spain and Portugal.
