13 inch Macbook Pro Battery problems (normal?)

[pianodude123]

Hi,

I've been closely tracking the status of my 13 inch macbook pro's battery using Coconut Battery.

I noticed that I have 56 cycles since July of 2009, but my full charge capacity is already at 84%

Is this normal? My sister's Macbook is still at about 95% and she got hers before me! I know about battery care too, so I've been cycling every month, etc... she's just been using her computer normally!

i have a feeling some1 is gna say "coconut battery isnt always 100% accurate". so ill say it first

probably nothing to worry. if it dies or go bad, i think youll get it replace...for free? lol. mine is only 9 cycles and im at 97% =_=

OP said he had been cycling every month. Perhaps he meant to say 'callibrating.' Maybe OP was doing it wrong and reading the support page will help.

I'm 11 cycles in and still at 100% so I don't know... 84% seems a bit low for only that many cycles.
