Frequently asked questions
How do I know if this 42T4833 battery is compatible with my Lenovo laptop?
To ensure compatibility, check the part number on your original battery's label. If it matches 42T4833 or any of the equivalent part numbers listed (such as 42T4691 or 42T4832), this battery is correct. It is also compatible with specific Lenovo ThinkPad T400s, T410s, and T410si models.
Is it necessary to calibrate the new battery the first time?
Yes, it is recommended. To calibrate it, charge the battery to 100% with the laptop turned off. Then, turn it on and use it with the battery until it is completely depleted and the device turns off. Finally, charge it back to 100% without interruptions. This process helps the operating system display the charge level accurately.
What warranty does it have and what do I do if it doesn't work or fit?
The battery has a 3-year warranty for private customers (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 shipping on your own 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 our products are shipped from Spain. For orders in Spain and Portugal, the delivery time is 24 to 48 business hours. For other EU destinations, such as France, the delivery time is 48 to 72 hours, and for Germany, 48 to 96 hours.
My original battery is 10.8V, can I use this 11.1V one?
Yes, 10.8V and 11.1V voltages are compatible with each other in lithium batteries. This slight difference is due to the way the nominal voltage of the cells is measured and does not affect the operation or safety of your laptop. You can use this 11.1V battery without any problem.
