Frequently asked questions
How do I know if this battery is correct for my Lenovo laptop?
The safest way is to check the Part Number of your original battery. Remove it and look for a code like 42T4833, 42T4691, or similar. If it matches any from the 'compatible part numbers' list on this page, it is the correct one. The laptop model (e.g., T410s) is a good guide, but the part number of the component is the definitive confirmation.
Do I need 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 it is completely depleted and turns off by itself. Finally, charge it back to 100% without interruptions. This process helps the system recognize the battery's actual capacity and display accurate charge percentages.
What warranty does the battery have and what do I do if it doesn't work or fit?
The battery has a 3-year warranty for private customers and 1 year for professionals. If upon receipt it does not fit or does not work, you have 14 days to return it. You can manage the return shipment on your own or request a home collection for 8.90 € in Spain and Portugal, which will be deducted from the refund.
