I have been using my 13" MBP with a monitor for the past few months now and I just noticed that sometimes i look up at the battery status and it is plugged in and it says in parentheses not charging. I press the button on the side of the MBP and it indicates it is at about 80%. I left the MBP at home all day plugged in and i was wondering if it is doing its own battery maintenance or what.

Does anybody else have this issue?
 
It will stop charging sometimes between 93% and 99%, but not as low as 80%. You may have a faulty connection or charger. Batteries don't do their own maintenance.

This should answer most, if not all, of your battery questions: Apple Notebook Battery FAQ

Its not that it stopped charging at 80%, It was charged this morning at 100%, i never took it off the charger and i noticed it tonight that it was saying not charging and the battery was at 80% ish

Read the link I posted, especially the sections on calibration and charging.
