Frequently asked questions
How do I know if this BT.00604.049 battery is compatible with my laptop?
The safest way is to remove your current laptop battery and check the part number printed on the label. If it matches BT.00604.049, this battery is correct. You can also compare the voltage (V) and physical shape with the product images to ensure a perfect fit.
My original battery is 10.8V and this one is 11.1V, is it compatible?
Yes, it is fully compatible. 10.8V and 11.1V batteries are interchangeable, as they use the same type of lithium cells (3.6V and 3.7V respectively). Laptop circuits are designed to manage this small voltage difference without any problem.
Do I need to calibrate the battery the first time I use it?
Yes, it is recommended. To calibrate it, charge the battery to 100% the first time. Then, use it until the laptop shuts down due to low battery (approximately 5%). Finally, recharge it to 100% without interruptions. This process helps the operating system recognize the actual capacity of the new battery and display the charge percentage accurately.
What warranty does it have and what 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 it is not compatible or has any defect, 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.
How long does it take for the order to arrive at my address?
All orders are prepared and shipped from our warehouse in Spain. For Spain and Portugal, the delivery time is 24 to 48 working hours. For other EU countries, such as France or Germany, the delivery time may vary between 2 and 5 working days.
