Will my MacBook's battery be damaged if I do not use for next couple of months?
I bought a new Macbook Pro (March 2015) a month back. So far I have not started using it yet. It's charged and box packed as I do not currently have time to set it up for my development work.
Update: It's charged 90%+ but not being used.

These are what you need to keep in mind:
If you are storing the MacBook for a few months, take better care where you store it. Place it in a case, or completely dry bag to prevent dust buildup. Even if you keep it in the box it has come with, it would be fine.
Taking the above care, you don't have to worry about the battery.
