Frequently asked questions

How do I know if this SB10J78998 battery is compatible with my Lenovo laptop?

The safest way is to remove your current battery and check the part number printed on the label. If it matches SB10J78998 or any of the listed compatible part numbers (such as 01AV400, 01AV401, etc.), this battery will work for you. You can also check if your laptop model is on the list of compatible models, such as the ThinkPad 13 Gen 2.

Is it necessary to calibrate the new battery the first time I use it?

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, recharge it to 100% without interruptions. This process helps the operating system recognize the actual capacity of the new battery and display the charge percentage accurately.

How many hours of actual autonomy can I expect from this 3735mAh battery?

Autonomy varies greatly depending on laptop usage (screen brightness, running programs, WiFi/Bluetooth connectivity). This 42 Wh battery is designed to offer a duration similar to that of the original battery when it was new. Generally, you can expect between 2 and 5 hours, depending on the workload and your device's power saving settings.

What warranty does it have and what do I do if it doesn't work or isn't the correct one?

The battery has a 3-year warranty for private customers and 1 year for professionals. If upon receipt it is not compatible or does not work correctly, you have 14 days to return it. You can manage the return yourself or request a home collection for 8.90 € in Spain and Portugal, which will be deducted from the refund.
