I never use my mbp battery since the day I bought it. As one of the Apple technical guy, I always trying to avoid using battery. Believe it or not my battery charge cycle is still 0.

I use MagSafe adapter all the time. My boss also didn't recommend me to use battery when I'm at home or office. Even if I go to starbucks, I'll search for wall socket.
I'm thinking if one day I sell my mbp to get a new one, at least the battery can help to boost up the price.

Good question. If starbucks run out of wall socket, I'll just sit there with a cup of ice blended mocha and wait till those wall socket to be available. I ever bring an extension socket to starbucks and shared with other people. No a big deal. As long as everyone is happy.
Battery won't charge after didn't use for 1 year? Guess what? You must be using it on and off right? If you already use your battery, it is good to use it once in a while. Unless you are like me, which I never use it or charge it since the day I got it.

Not really. Like I said, if you have used your battery, continue using it. Until your battery is dead and when you get a new one, if you plan not to use battery at all, then just leave the battery out there. Don't even charge it when u first get it.

Well, different people different thinking and opinion.

Hahaha that is true but I guess so far I'm lucky enough that no one bump into my a/c adapter. By the way, i do use power surge protector. so no big deal at the moment. Unless I go to starbucks, hmmm... should have gotten myself a portable power surge protector... hmm..

No sweat. Hahaha still different people different opinions.

Hahaha dude, you've know me for such a long time and you've seen my mbp running completely without battery. Hahaha

Yes! Apple will replace it with a new one in the warranty period.
