Frequently asked questions
How do I know if this 45N1705 battery is compatible with my Lenovo ThinkPad?
The safest way is to remove your current battery and check the printed part number. If it matches 45N1705 or any of the listed compatible part numbers (45N1704, 45N1706, etc.), it is the correct one. You can also check if your laptop model, such as the ThinkPad S1 Yoga (20C0, 20CD), is on our list of compatible models.
Do I need to calibrate the new battery after installing it?
Yes, it is highly recommended for the operating system to display the actual charge percentage. To do this, charge the battery to 100%, use it until the laptop shuts down due to low battery, let it rest for a few hours, and finally charge it back to 100% without interruptions. This process helps synchronize the battery with the system.
How many hours of battery life can I expect from this battery?
The duration depends on laptop usage (screen brightness, running programs, WiFi). With 47Wh capacity, you can expect autonomy similar to that of the original battery when it was new, which usually ranges between 2 and 5 hours for moderate office or browsing use.
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 shipping yourself or request a home pickup for 8,90€ in Spain and Portugal, which will be deducted from the refund.
How long will it take to arrive if I order it today?
Orders placed before 16:00 (15:00 on Fridays) are prepared on the same day. Shipping to Spain and Portugal takes between 24 and 48 working hours. For other European Union destinations, the delivery time is 2 to 5 working days.
