I was wondering if anyone can tell me if my macbook battery health is normal. Its at 89% battery health with 110 cycles and i've had it since April 2010. Original Capacity 5,450 MAH 100% Current Capacity 4,825 MAH 89% (current) calibration brought it down to 84% than up to 86% and it went back up to 90% and staying around there. Was initially 95% before the calibration. I calibrate every 1.5 months.
