Use your Mac until the battery runs out, then plug it in until it's fully charged.
Hey Zephead, the MacPro guide is a tad more exact.
To calibrate the battery:
1. Plug in the MagSafe power adapter and fully charge the MacBook or MacBook Pro battery until the light on the MagSafe connector changes to green and the Battery icon in the menu bar indicates that the battery is fully charged.
2. Allow the battery to rest in the fully charged state for two hours or longer. You may use your computer during this time as long as the power adapter is plugged in.
3. Disconnect the power adapter with the computer on and start using it with battery power. When the battery's charge gets low, youll see the low battery warning dialog on the screen.
4. Continue to keep your computer turned on until it goes to sleep. Save your work and close all applications when the battery's charge gets low and before the computer goes to sleep.
5. Turn off the computer or allow it to sleep for five hours or longer.
6. Reconnect the power adapter and leave it connected until the battery is fully charged. You may use your computer during this time.

Is there any good program that does something similar to this, but doesn't require 10.4? I'm still running 10.2.8 on my old iBook (well, dual boot with OS9), but I'd like to find out if I'm helping the battery at all by continuing to calibrate it.
^ your battery sucks compared to mine. 39 cycles and that? that is .0235897 percent per cycle. Mine is .0012006 percent per cycle.
I think this thread should be moved to the picture gallery form and renamed Post Your Battery Condition.

Here is mine. I guess my computer was made sometime in January because it will be 7 months since I got it new in a few days.
I guess my battery is in ok shape. I use it completely at least once a month... and I use it a little here and there almost every day. school and such ><
