Using Your MacBook Pro

If the battery icon in the Finder menu bar is set to show the percentage of charge, you

might sometimes notice that the battery does not attain a full 100 percent charge

when the power adapter is attached. This is normal behavior; battery life is maximized

if charging is not continuously cycled on and off when the battery’s charge capacity is

between 95 and 100 percent. When the battery level eventually drops below 95

percent, it will charge all the way to 100 percent.

Removing and Replacing the Battery

For instructions on removing and replacing the battery, see “Installing Additional

Memory” on page 84.
