Frequently asked questions
How do I know if this C665H battery is compatible with my Dell Latitude?
The safest way is to remove your current battery and check the part number printed on the label. If it matches C665H or any of the part numbers listed as compatible (U817P, W8H5Y, etc.), this battery is the correct one. You can also check if your laptop model, such as Dell Latitude E4300 or E4320, is on the list of compatible models.
Do I need to calibrate the new battery the first time I use it?
Yes, it is 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 discharged and the device turns off. Finally, recharge it to 100% without interruptions. This process helps the operating system recognize the battery's real capacity and display the charge percentage accurately.
How many hours of autonomy can I expect from this battery?
Autonomy depends on your laptop's consumption (screen brightness, CPU usage, etc.) and the wear of other components. This 4400mAh battery is designed to offer a duration similar to that of the original battery when it was new. Generally, you can expect between 2 and 4 hours of moderate use, but this value is indicative.
What warranty does it have and what should I do if it doesn't work or fit properly?
The battery has a 3-year warranty for private customers (1 year for professionals). If upon receipt it does not fit or does not work correctly, you have 14 days to return it. You can manage the return yourself or request a home collection for 8.90 € in Spain and Portugal, which will be deducted from the refund. Contact our customer service to start the process.
How long does it take for the order to arrive at my address?
All our orders are shipped from Spain. For Spain and Portugal, the delivery time is 24-48 working hours.
