Frequently asked questions
How do I know if this CP284 battery is compatible with my Dell laptop?
To ensure compatibility, the most reliable way is to remove the original battery and check the printed part number. If it matches CP284 or any of the equivalent PNs such as U817P, W8H5Y, or XX327, it is the correct one. You can also verify if your laptop model, such as the Dell Latitude E4300 or E4320, is on our list of compatible models.
Is it necessary to calibrate the new battery the first time?
Yes, an initial calibration cycle is recommended. Charge the battery to 100%, let it rest for an hour, then use it until the laptop shuts down due to low battery (approx. 5%). Finally, charge it again to 100% without interruptions. This helps the system recognize the actual capacity and optimizes its long-term performance.
What autonomy can I expect from this battery?
Actual autonomy depends on laptop usage (screen brightness, running programs, Wi-Fi). With 4400 mAh and 49 Wh, this battery offers a duration similar to the original when it was new. You can expect several hours of office use or browsing, although this time will be reduced with more intensive tasks.
What warranty does it have and what do I do if it doesn't work or fit?
We offer 3 years warranty for private customers and 1 year for professionals. If the battery 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.
