    That is normal. It doesn't always charge to 100%.

    that would seem strange. only rarely did it ever say 100% but why would it not sometimes. Does it have something to do with the battery?

    It's to prevent overcharging.

    This should answer most, if not all, of your battery questions: Apple Notebook Battery FAQ. Read the section on Charging for the exact answer to your question.
