Hi, I bough my rMBP at 12 August 2012. I bought it with AppleCare so my warranty ends in 12 August 2015. Info from Apple's System Information Cycle Count: 534 Condition: Normal Info from CoconutBattery Cycle Count: 534 Health: %81.9 As for as I know, it is OK for %80 up to 1000 cycles. Mine is half of it but it is at about %82 I picked up my rMBP just a days ago from Apple. The main issue was different but I said them I have battery health problem too. After picking up they said that they checked up from their own special Test Programs and battery is OK and does not require any replacement. The health will drop definitely before 1000 cycle. If it is %82 in 534 cycle, imagine what will it be like in 3-4 months. Should Apple replace my battery or not?
