Hi, I just checked the battery health and it went from 95% yesterday to 82% now. WTF??? I would ask: |is this normal? " but i think I can safely answer that myself. Current battery capacity : 4663 Original Battery capacity: 5600 Battery cycles: 63 Age of your mac: 8 Months. I supposedly got this NEW from macmall on January 7, 2009. Should I get the battery replaced or wait. I have also done the calibration a couple of times. The battery fluctuated from 94 to 97, but never below 94 The only new thing I added to my set up is a Notepal W2. I notice that the vents blow right under the battery, but I would not thing that makes a difference. (I just got it this morning) any ideas?
