Frequently asked questions
How can I ensure this battery is correct for my Lenovo laptop?
The safest way is to turn off your laptop, remove the battery, and read the part number printed on it. If it matches 45N1088, 45N1089, L11S3P51, or any of the other P/Ns in the compatibility list, this battery is correct. You can also check if your laptop model, such as the ThinkPad T430u, is on the list of compatible models.
Is it necessary to calibrate the battery the first time it's used?
Yes, an initial calibration cycle is recommended. Charge it to 100%, use it until the laptop turns off or warns of very low battery, and then recharge it to 100% without interruptions. This process helps the operating system recognize and display the actual capacity of the new battery.
What autonomy can I expect from this 4250mAh battery?
Battery life largely depends on laptop usage, screen brightness, and running applications. For standard office use and web browsing, you can expect between 2 and 4 hours of autonomy. More intensive tasks like video editing or gaming will reduce this time.
What warranty does it have and how does the return work if it's not compatible?
This battery has a 3-year warranty for private customers and 1 year for professionals. If upon receipt you find it is not compatible, you have 14 days to return it. Return shipping is at your expense, or if you prefer, we can arrange a home collection for 8.90 € in Spain and Portugal, which will be deducted from the refund.
