4 Carefully pull the battery out of its compartment.
5 If you are inserting another battery, slide it into the battery compartment.
Replacement batteries come with a door attached.
6 Close the battery door by pushing it back into place.
7 If you just inserted a new battery, it’s a good idea to plug in the power adapter in case
the battery is not fully charged.
Disposing of dead batteries
If you have a battery that can no longer be recharged, you will need to buy a
new battery and dispose of the dead battery properly.
IMPORTANT Nickel-cadmium batteries contain metals that are hazardous when
released to the environment. It is inappropriate, and in some cases unlawful,
to throw batteries away with your household or business trash. There are other
ways to dispose of them.
In the United States: Return dead batteries to your Apple-authorized service
provider, who will make sure they are included in Apple’s battery recycling
program.
Elsewhere: Many countries have government- or Apple-sponsored collection
and/or recycling programs for dead batteries. Dispose of dead batteries in
accordance with the mandatory or voluntary battery collection schemes in
your country. Contact your Apple-authorized service provider for information
about the recommended battery disposal procedures in your location. If there
is no government- or Apple-sponsored return program, you can dispose of the
batteries with your regular trash, but take care not to break them open or
incinerate them.
WARNING Damaged nickel-cadmium batteries may leak small amounts
of potassium hydroxide. This substance can cause severe burns to the
skin and eyes. If you touch a damaged battery, immediately wash your
hands and any other affected areas with water for at least 5 minutes.
Do not use soap.
