Product description
The battery with reference X855G is a replacement component specifically designed to restore autonomy in Dell Latitude laptops. It operates at a nominal voltage of 11.1 V and offers a capacity of 4400 mAh (equivalent to 49 Wh), thanks to its internal configuration of 6 Lithium-Ion (Li-Ion) cells. This technology ensures a prolonged lifespan and the absence of memory effect.
This component is the ideal solution for replacing a defective or depleted original battery, allowing the device to function again without needing to be permanently connected to power. It includes protection circuits against overcharge and over-discharge to ensure the safety of both the component and the laptop.
Before making a purchase, it is recommended to verify the part number printed on your laptop's original battery to ensure full compatibility.
It is essential to check that the part number of your original battery matches X855G or any of the listed compatible part numbers. The voltage difference between 10.8V and 11.1V is nominal and fully compatible in 6-cell batteries, so it does not affect the equipment's operation.

Frequently asked questions
How can I tell if this battery is correct for my Dell Latitude?
The safest way is to remove the current battery from your laptop and look for the part number printed on the label. If it matches X855G or any of the codes in the 'compatible part numbers' list (such as U817P or W8H5Y), this battery is correct for your device.
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% with the laptop turned off. Then, turn it on and use it normally until the battery level drops to 10-15%. Finally, charge it back to 100% without interruptions. This initial cycle helps the operating system recognize the real capacity.
My original battery indicates 10.8V, is this 11.1V one compatible?
Yes, it is fully compatible. For 6-cell Li-Ion batteries, 10.8V and 11.1V voltages are nominally equivalent and interchangeable. The laptop's circuit is designed to manage this small variation without any issues.
What warranty does it have and how does the return work if it's not compatible?
The battery has a 3-year warranty for private customers (1 year for professionals). If it is not compatible or you simply change your mind, you have 14 days to return it. You can arrange the return shipment yourself or request a home pickup for 8.90 € in Spain and Portugal, which will be deducted from the refund.
How long does the order take to arrive?
All orders are prepared and shipped from our warehouse in Spain. For destinations in Spain and Portugal, the delivery time is 24 to 48 business hours. For other EU countries, the timeframe varies between 2 and 5 business days.
