Replacing the Battery
Your computer has a 3.6 V lithium battery installed on the main logic board. Some signs that
you need to replace the battery are intermittent problems starting up the computer and
random changes in its date and time settings. You can purchase a replacement battery from
an Apple-authorized dealer.
1 Remove the battery from its holder, noting the orientation of the battery’s positive end. (Plus
and minus are also marked on and near the battery holder.)
Important Batteries contain chemicals, some of which may be harmful to the environment.
Please dispose of used batteries according to your local environmental laws and guidelines.
Remove the battery by pulling it
up and out of its holder. You may
need to spread these two tabs
slightly apart to release the battery.
Spread the tabs gently so they
don’t break.
