How to manage my MacBook Pro battery?

I have a macbook pro and i was wondering what you guys do?
do u keep the charger in at all times? do you take it out after its fully charged and use it? cause im wondering if im doing the best possible thing.

Typically you can keep your charger in when you are using it at home or whenever power is available. Apple recommends that you drain the battery and calibrate it before you first use it and then once again once every month regardless of the type of use you subject it too. The first thing you need to do is charge your computer till the adapter light is green and the onscreen indicator shows 100%. Next let the battery rest in the fully charged state for at least 2 hours. You can use you computer normally during this time. After 2 hours disconnect the power adapter while the computer is still on and let the computer run using battery charge. Once the indicator gets low and warns you it is about to shut down save everything and let the computer go to sleep. Let your MacBook sleep for about 5 hours and then connect the power adapter again and leave it connected until the battery is completely charged.
My answer is that a good way to manage the Macbook battery is to run your Macbook on battery power, or run the battery down, and then recharge it. Do this for at least the first several times, this helps your Macbook run at a rate close to its "ideal" battery life of 7 hours, and also helps slow down the rate at which the battery deteriorates, or shortens in its life span over time.
