Key Points For Your Mac Battery to Last Long.

With a little bit of care you can maximize your battery life and performance of your Apple Notebooks . The most important thing is not to keep your Apple Notebook in hot places. Heat degrades your battery's performance the most.
Make sure you keep your battery softwares updated.
It is not good to always keep your portable laptop to be plugged in all the time. Do use it on battery at least once a day or two to keep the battery juices flowing.

Caliberate your battery for accuracy

1. Plug in the power adapter and fully charge your
   PowerBook's battery until the light ring or LED on the power adapter
   plug changes to green and the onscreen meter in the menu bar indicates
   that the battery is fully charged.
2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
3. Disconnect the power adapter with the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, you will see the low battery warning dialog on the screen.
4. Continue to keep your computer on until it goes to sleep. Save all your work and close all applications when the battery gets very low, before the computer goes to sleep.
5. Turn off the computer or allow it to sleep for five hours or more.
6. Connect the power adapter and leave it connected until the battery is fully charged again.

Tip: When the battery reaches "empty", the computer is forced into sleep mode. The battery actually keeps back a reserve beyond "empty", to maintain the computer in sleep for a period of time. Once the battery is truly exhausted, the computer is forced to shut down. When power is restored, the computer returns itself to its pre-sleep state using the safe sleep image on the hard drive.
