well , u should know that the fact that the battery is going weaker even u have never use it. that is the characteristic of li-ion battery . from day 1 out from the shelf , it is deteriorating, the cell inside it has to be actively charged , that is why the recommended shelf keeping charge is 50% .

its up to you , but i dont hope people will follow the wrong procedure here .
anyway , i respect the purpose of a laptop , which is using the battery .hehehehe
