Frequently asked questions
How do I know if this battery is compatible with my Dell Latitude?
The safest way is to check the part number printed on your original battery. If it matches CP289 or any of the part numbers listed in our compatibility section (such as U817P or W8H5Y), it is the correct one. You can also check if your laptop model, such as the Latitude E4300, is on the list of compatible models.
My original battery is 10.8V and this one is 11.1V, is that a problem?
No, it is not a problem. 10.8V and 11.1V voltages are functionally identical for this type of 6-cell battery (3 groups of cells in series) and are completely interchangeable. Your laptop's charging circuit is designed to manage this small variation without any risk.
Is it necessary to calibrate the battery the first time I use it?
Yes, it is highly recommended. To calibrate it, charge the battery to 100%, then use it until the laptop shuts down due to low battery. Finally, recharge it to 100% without interruptions. This process helps the operating system accurately display the remaining charge percentage.
What warranty does it have and how can I return it if it doesn't fit?
We offer a 3-year warranty for private customers and 1 year for professionals. If the battery is not compatible or you simply change your mind, you have 14 days to return it. You can arrange the return shipping yourself or request a home collection for €8.90, which will be deducted from the refund.
How long does it take for the order to arrive in Barcelona?
All our shipments are made from our warehouse in Spain. For any destination in peninsular Spain, including Barcelona, the delivery time is 24 to 48 business hours if you place your order before 16:00.
