    I bought my macbook this last July, (5months ago) I used coconut battery.app and it shows my battery only able to charge up to 4784mAh instead of the original 5200mAh and that it's 9 months old. What is the deal??? I have tried calibrating and it doesn't help. Do I have to calibrate 3 times one after the other or something??? Did apple do a recall on any batteries that I might not be aware of?? Also, this is for my 13.3in macbook 1.83GHz.

    Batteries lose their charging capacity over usage time.

    I can understand this maybe in a year but just a few months and 10% of battery life gone??? That is unacceptable

    Actually, it is pretty acceptable. Maybe only a single percent worse than the norm.

    Ummm to be honest... I dont think this is something you should be complaining about every laptop battery (not just apple ;)) loses its charge.

    Unfortunately for you, me and everyone else that has an apple product the battery is not covered under Apple care!

    You are fortunate. A friend plugged his 17" powerbook charger into my 12" powerbook and now my battery has 40% health! Just holds up for a DVD episode of 24 mind you though! Ha Thats all I really need the battery for!

    My MBP is as old as the OP's and I was down to 50% battery life according to coconut battery. I called apple, and posted on their support discussion forums about it. Neither apple nor other users thought it was unusual. The users on the support forum stated that the battery is only supposed to last around 300 or so charging cycles. How many does coconut battery state you have?

    Funny thing is, after upgrading to leopard last week, coconut battery is now reporting I'm at 91% of the original capacity. Of course, it now says I've had 5 load cycles, and I was at approximately 100 before the upgrade.

    The battery has a 1 year warranty independent of AppleCare.
