I just purchased a 2.16 ghz MB about a month ago. After my initial battery calibration, coconut battery showed 95% health. Now after another battery calibration and about 5 chage cycles in between the calibrations, coconut shows 94% battery health, with only 8 cycles. Does this seem like normal batery wear or should I be calling up apple to see about a replacement?
Here is the coconut screenshot

They will replace it under warrantee if it falls below 50% within a year (or two years, I am not sure)

Yes but I've heard of others getting replacement batteries that were experiencing conditions like I am having.

I know I'm a whiner but it's basically brand new!! I just want everything to be perfect on my first mac. I know others feel the same with all the other battery related threads.
it will most likely go up in health again, mine's been changing from time to time, always around 93 to 99% and once at 87% :eek:

Wow, wish I knew Coconut battery did history.

I have been taking screen shots for about 3 months because I have been getting widely fluctuating battery Max Charge levels.

Its a replacement battery from Apple last year so its less than a year old and done 169 cycles but now reports anywhere from 4675 (originally 5500) to 2709 (49%).

Every few days / hours it can jump from the 4600s to the 3000s or below. Anyone got any advice?
