Battery Replacement
The battery that comes with the computer provides power to the
real-time clock. When replacing the battery, use a battery equivalent
to the battery originally installed in the computer. The computer
comes with a 3-volt lithium coin cell battery.

The lifetime of the lithium battery can be extended by plugging the
computer into a live AC wall socket. The lithium battery is only used
when the computer is NOT connected to AC power.
