Hi I've done the research and am aware that the unibody MBP do not need battery calibration, altho i have read some sites that state calibration maybe needed the first time for brand new MBPs, i guess this is debatable? Anyways in my case I had to replace my mid 2012 battery because it died on me, so i bought a new battery from apple and replaced it myself, it now has 69 cycles but the thought of calibration came to mind, since this battery is a replacement, and the system and battery someway/somehow need to be calibrated for proper reading. currently my battery health fluctuates between 93% - 92% with an average FCC of 5350mAh. My previous battery had about 650 cycles and held a consistent health of 96%. So my question is, what are the procedures in calibrating the battery for the unibody? Do I follow the same steps as the MBP with replaceable batteries?
