So for a year, my battery has been above 95% max capacity, and i've been very happy. I could close the lid of the MBP and it would sleep for days without using any battery, well a very very small amount. Then last week, it dropped down to 60% max capacity, and i've only got 75 cycles on it. Also, it will eat 15% battery overnight if i have it sleeping, and it will never stop charging, it just keeps going. I found a battery replacement thing on Apple's website, well one of you guys linked it to me, but it might only cover the core duo MBP, but i purchased mine in the correct time they list. Any suggestions or should i just go to an apple store and have them look at it?
