So I was talking to a friend of mine about whether to keep our MBs plugged in or not. On Apple's site it says the battery's designed to deliver 1000 charge cycles before reaching 80%. I'm at 80% right now with only 346 charge cycles. Is this covered under AppleCare? I'm covered until August but I'd like to make sure if it's covered it gets taken care of. Anyone have experience with this?
