6 If you are inserting another battery, move the slider to expose the contacts, then slide it
into the battery compartment.
You cannot insert a battery when the protective slider is covering the battery
contacts.
7 If you are not inserting another battery, attach the battery compartment cover to prevent
dust or debris from accumulating in the empty compartment.

the batteries are not fully charged.
IMPORTANT Nickel-metal-hydride (NiMH) batteries contain metals which
are hazardous when released in the environment. It is inappropriate, and in
some cases unlawful, to throw batteries away with your household or business
trash. Instead of throwing away your spent batteries, dispose of them as
described here.
m
In the United States Return spent batteries to your Apple-authorized service
provider, who will make sure they are included in Apple’s battery recycling
program.
m
Elsewhere Many locations have government or Apple-sponsored collection
and/or recycling programs for spent batteries. Dispose of spent batteries in
accordance with the mandatory or voluntary battery collection programs
in your location. Contact your Apple-authorized service provider for
information about the recommended disposal procedures in your area.
WARNING Damaged nickel-metal-hydride 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 five
minutes.
Do not use soap.
