By cons we must know that this battery is larger than the original, that you can not lay your notebook "flat" because the battery exceeds 3-4 centimeters is also a point not néglier not for transport.
And also, we can not unfold the screen as much as with the conventional battery.
It can raise the keyboard as a fixed PC keyboard, which is more convenient for typing text.
For my use, home of a room to another there are no worries, capacity makes it possible to recharge the battery at night, it lasts much all day, even in heavy use
