Macbook pro 2011 maximum plug in time

Question

I just got a new macbook pro 2011 and within a within a week I already have 9 charge cycles. The way I've been using it everyday, I'll charge it to 100% and then take it off, let it go down to 30-50%, and plug it back in till 100%. Using it like this everyday for a week has given me 9 charge cycles and I realize its bad because you need 1-2 a week.
-So is it better for me to leave it plugged in for 3-5 days straight and then take it off the power.. let it go down to 50%.. and then back to 100?
-What is the maximum amount of time that I can leave it plugged in continuously if I want 1-2 charge cycles per week - I feel apple's suggestion of not leaving it plugged in "all the time" is unclear on what "all the time" really is.

Answer 1

I realize that article says not to run on AC power all the time. But what exactly is all the time?
All the time is ALL the time. If you plug your computer into AC power and leave it plugged in for six months, you'll permanently damage the battery. Leave it plugged in for a year and the battery may be dead and impossible to charge. A notebook computer is not a desktop computer — its battery needs to be used at least a little on a regular basis.
If you never need to use the battery at all, Apple says you should calibrate it (see link in the article you've already read) a minimum of every month to keep the battery in usable condition.
If you never need the battery, why should you care whether or not it's in usable condition? Three reasons: 1) if the AC power goes out while you're working, the battery will instantly take over and prevent any of your unsaved work from being lost; 2) if the battery is dead, your processors will run at lower speeds; and 3) a good battery will enhance the resale value of the machine if and when the time comes to sell it.
