I just got a Macbook Pro 13" and I wanna try to prolong the battery life as long as I can.. Not like my HP laptop where I could just easily pop out the battery and have the comp running on the AC adapter.. Is the best way to just be plugged in whenever I have the chance? or drain the battery and recharge?

Read and follow Apple's guide to caring for the batteries in their laptops (MacBook, MacBook Pro) -- http://support.apple.com/kb/HT1490

IApple recommends you "calibrate your battery...every two months":

From that linked page:

Calibrating your battery ensures you get the longest possible running time from it. Calibrate your battery during the first week you own it, and then recalibrate it every two months. If you use your computer infrequently, it’s best to recalibrate it at least once a month.

Whenever you purchase new batteries, calibrate them as well.

To calibrate a portable computer battery:

  1. Plug in the MagSafe Power Adapter and fully charge the battery.

When the battery is fully charged, the light on the MagSafe Power Adapter connector changes to green and the Battery icon in the menu bar indicates that the battery is charged.

  1. Allow the battery to rest in the fully charged state for two hours or longer. You can use your computer during this time as long as the power adapter is plugged in.

  2. With the computer still on, disconnect the power adapter and continue to use your computer.

  3. When you see the low battery warning, save your work and close all applications. Keep your computer turned on until it goes to sleep.

  4. After your computer goes to sleep, turn it off or allow it to sleep for five hours or longer.

  5. Connect the power adapter and leave it connected until the battery is fully charged. You can use your computer during this time.

No, straight from Apple, "Apple does not recommend leaving your portable plugged in all the time."

You can read more about what Apple recommends by reading their Apple - Batteries - Notebooks page at http://www.apple.com/batteries/notebooks.html

You can choose to use your Apple notebook in a way that maximizes its battery life.

Energy: The Energy Saver control panel offers several settings that determine power levels for your Macbook. Your portable knows when it’s plugged in, and runs accordingly. When on battery power, it will dim the screen and use other components sparingly. If you change this setting to maximize performance, your battery will drain more quickly.

Brightness: Dim the screen to the lowest comfortable level to achieve maximum battery life. For instance, when watching a DVD on an airplane, you may not need full brightness if all the lights are off.

AirPort Wireless: AirPort consumes power, even if you are not using its features to connect to a network. You can turn it off in its control panel to save power.

Bluetooth Wireless: Likewise, you can turn off Bluetooth to maximize your battery life, as it also consumes power when not in use.

Applications and peripherals: Disconnect peripherals and quit applications not in use. Eject CDs and DVDs if not currently accessing them.
