I am completely satisfied with this battery. He does what needs to keep a battery. I bought this battery as magnification for my Thinkpad T440s, which has two batteries (standard an internal (permanently installed) battery with 3 cells and an external (removable) battery, also with 3 cells). This battery brings me (in combination with the fixed battery) loosely over the day without power. Even when running computationally more joyful programs makes the battery is not weak and lost only by its 13-hour battery time is one hour a. As usual top quality from Lenovo!
The only disadvantage of the battery: With its dual cell count of battery is significantly higher than the 3-Zeller. He stands out in the downward direction, which Lenovo has but established as a practical "notebook tilt function", so that one even suggests a benefit from the fact that now the notebook is slightly bent and you achieved all the buttons better. But this is a matter of taste and everyone must decide individually if he can work with it or not.
