Frequently asked questions
My original battery indicates 10.8V, is this 11.1V one compatible?
Yes, it is fully compatible. Lithium-ion batteries with 3 or 6 cells can have nominal voltages of 10.8V or 11.1V depending on the cell manufacturer. Both voltages are interchangeable and will not affect your laptop's operation or safety. The device's charging circuit is designed to manage this small difference without issues.
How do I know if this is the correct battery for my laptop?
The safest way to confirm is to remove your laptop's battery and compare the part number printed on it with the reference BT.00603.111. If it matches, this is the battery you need. You can also compare the physical shape and connector positions with the product images.
Is it necessary to calibrate the new battery upon receipt?
We recommend an initial calibration cycle to ensure the operating system displays the charge percentage correctly. To do this, charge the battery to 100%, let it rest for an hour, then use it until the laptop shuts down due to low battery (approximately 5%), and finally, recharge it to 100% without interruptions.
What warranty does it have and how can I return it if it doesn't work for me?
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 shipment yourself or request a home collection for 8.90 € in Spain and Portugal, which will be deducted from the refund.
