Macbook Pro battery

[MrRoyksopp]

Hello everyone.
- I just want to ask this question:
If I have the power plugged in to my MBP while it's fully charged, does it then effect my battery life?

Cause I see a lot of people who have their power plugged in, when it's already fully charged.

So, can I run it in for example clam shelled mode, without thinking about the battery life on my MBP?

it's fine to keep your computer running on a/c power with the battery at 100%, but every now and then pull the power and make the computer run off of battery until it's been depleted, then charge it up again. Doing this a couple times a month ensures optimal battery life.

Thanks a lot!
The answer I were looking for.

I thought apple say to only do that once every 2 months?

thats the Full calibration, which means letting it run down until it suspends, then letting it continue to drain until the suspend light goes off, then leaving it another 5+ hrs, its a pain in the ass to do for me as it can take me out of action for 10+hrs between it suspending and being able to start using it on mains again.. luckily that will be a thing of the past as im getting a new imac as soon as they release lion.

You don't need to run it down completely. Running it down to around 50% or so every few days will work just fine. This should answer most, if not all, of your battery questions:
