I have a MBP 13" and it's on 96% health... with only 70 charge cycles. I know where to find how to calibrate my battery, but I don't think I'm making it right. My questions are about point 5 and 6. 5. Should I just turn off my MBP for 5 hours and then go to point 6. OR Turn off my MBP and go to point 6. and 6. Can I start using my MBP when the power adapter is connected OR I should wait until it's fully charged and then turn on my MBP.
