I need some clarification with charging the battery, I read this post and I need someone to explain this simply, what do I do?
"Also never let your macbook battery drain below 20%, always plug into the AC power if the battery gets to 20%. Ideally you should let the battery drain to 40-60% once every month so that the electrons in the lithium battery move about; otherwise I keep mine plugged in as I use my MBP as a desktop replacement. If you do let it drain to say 50% each month that means the battery will go through 1 full cycle every 2 months or 6 per year. The fewer cycles the better, but sooner or later you will have to replace the battery, as it is only designed for 1000 cycles."
