Frequently asked questions
How do I know if this 42T4691 battery is compatible with my Lenovo laptop?
To ensure compatibility, the most reliable way is to remove the current battery from your laptop and compare the part number printed on it. If it matches 42T4691 or any of the numbers in the equivalent list (such as 42T4833 or 42T4522), this battery is correct. You can also check if your model is a ThinkPad T400s, T410s, or T410si.
Do I need to calibrate the new battery after installing it?
Yes, it is highly recommended. To calibrate it, install the battery and charge it to 100% without interruption. Then, use the laptop until the battery is completely discharged and the device turns off. Finally, charge it back to 100% without using the device. This process helps the operating system display the real charge level and optimizes its lifespan.
How many hours of autonomy can I expect with this battery?
Actual autonomy depends on laptop usage, screen brightness, and running applications. With 3900mAh and 44Wh, you can expect a duration similar to that of the original battery when it was new. Generally, this translates to several hours of office or browsing use, although it will be less with intensive tasks.
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 and 1 year for professionals. If upon receipt it is not compatible or has any defect, 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.
