So I have had my MacBook Pro just over a month. I have been using coconutBattery 2.5.1 to collect data about the mAh capacity and how much this is decreasing. I figure I should be able to get 700 - 1000 battery loadcycles out of this battery before I need to get it replaced. I will be buying AppleCare as I need this computer to last through college (3 years). Maybe just before AppleCare expires I will be able to get a new battery through the system. Currently the machine has done 27 battery loadcycles and its 3 months old (I got it refurb-ish (long story). The original battery capacity was 5500 mAh but it is currently at 5518 mAh - this doesn't make sence to me so if someone could explain then that would be great. Anyway, using excel I collected the data from coconutBattery and put it into a nice graph for you guys. Obviously this shows the capacity going down, I presume this is at a steady rate and nothing out of the ordinary, but how can my batteries capacity be MORE than its original shipped capacity - normal???
