Frequently asked questions
How can I tell if this 45N1071 battery is compatible with my Lenovo laptop?
The safest way is to check the part number of your original battery. Remove the current battery and look for a label with the code. If it matches 45N1071 or 45N1070, this battery is correct. You can also compare the voltage (14.8V or 14.4V) and physical shape with the product images.
Is it necessary to calibrate the new battery the first time?
Yes, an initial calibration cycle is recommended. Charge the battery to 100%, let it rest for an hour, then use the laptop until it turns off due to low battery (approx. 5%). Finally, charge it back to 100% without interruptions. This helps the system recognize the battery's actual capacity.
What warranty does the battery have and how do returns work?
The battery has a 3-year warranty for private customers and 1 year for professionals. If you need to return it, you have 14 days from receipt. 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.
How long does the order take to arrive?
All our products are shipped from our warehouse in Spain. For orders in Spain and Portugal, the delivery time is 24 to 48 business hours. For other EU countries, such as France or Germany, the delivery time is usually 2 to 5 business days.
What is the approximate lifespan of this battery?
The lifespan of a new battery depends on laptop usage. Generally, it is expected to maintain optimal performance for 300 to 500 full charge cycles, which usually equates to several years of moderate use. To extend its lifespan, avoid frequent full discharges and exposure to high temperatures.
