Frequently asked questions
How can I tell if this battery is compatible with my Lenovo laptop?
To ensure compatibility, the most reliable way is to check the part number of your original battery. Disassemble the old battery and look for a label with a code like '01AV421' or '01AV419'. If your code matches any from the list of compatible part numbers, this battery will work for you. The laptop model can be misleading, as the same series may use different batteries.
Is it necessary to calibrate the new battery the first time?
Yes, it is highly recommended. Once installed, charge the battery to 100% without interruptions. Then, use the laptop until it is completely depleted and turns off by itself. Finally, charge it back to 100% without using the device. This complete cycle helps the operating system display the real charge level and optimizes the battery's lifespan.
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.
