Is there a chart or something like that where I can compare my battery health to? These are my specs, and I was just wondering if they are "normal." MBP 13" Mid - 2009 Battery Loadcycles - 80 Age - 8 Months Current Battery Capacity - 85% I tried calibrating my battery twice in that past two days to see if the capacity will jump, but it has not. Any information would be appreciated. Thanks!
