I have been tracking the maximum charge of my macbook pro's battery with the application coconut battery. However, I noticed a slightly disturbing trend:



How did my battery's maximum charge drop from 91% to 62% within the span of 30 days?

You MacBook is over a year old from that screen shot.

Did you check the serial number on your battery against the Battery Exchange Program serial number range? You might have a battery that is eligible for exchange. This has nothing to do with the Recall. Check Apple's site here:

If that is not the case, then try resetting the PMU on your Macbook.

Then see what happens.

Remember batteries are consumables so if the battery is just not lasing as long as it did when it was new that is normal and not covered by the warranty.

How do you reset the power manager on a macbook pro?

A simple search on Apple's support pages will tell you how. Here it is: http://docs.info.apple.com/article.html?artnum=303319

Even so, for a year old machine, a drop from 91% to 62% in the space of a month is by far and away not normal.

My Powerbook battery seems to have a problem after they took my pb in for the HD problem in January. Before January it seems to let me have a longer charge w/o my power cord hooked in. Not it seems to go from 100%-20% in 30 min or something.
