Frequently asked questions
How do I know if this 3XO21 battery is compatible with my Dell laptop?
The safest way is to check the part number printed on your original battery. If it matches 3XO21, U817P, W8H5Y, or any of those listed on the product sheet, it is compatible. You can also check if your laptop model, such as the Dell Latitude E4300 or E4320, appears in the list of compatible models.
Do I need to calibrate the new battery the first time I use it?
Yes, it is highly recommended. To calibrate it, charge it to 100% the first time. Then, use the laptop until the battery is completely depleted and the device turns off. Finally, recharge it to 100% without interruptions. This process helps the operating system recognize the actual capacity of the new battery.
How many hours of autonomy will this battery provide?
Autonomy depends on laptop usage (screen brightness, running programs, etc.). With a capacity of 49 Wh, you can expect a duration similar to that of the original battery when it was new, which is usually 2 to 4 hours for office tasks and web browsing.
What warranty does it have and do I do if it doesn't work or fit properly?
The battery has a 3-year warranty for private customers and 1 year for professionals. If upon receipt it is not compatible or you detect 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.
How long does it take for the order to arrive at my address?
Orders are prepared on the same business day if placed before 16:00 (15:00 on Fridays). Delivery in Spain and Portugal takes between 24 and 48 business hours. For other European Union countries, the delivery time is 2 to 5 business days.
