should last at least three years before you need to replace it.

Note: If you are storing the computer for long periods of time, you can
extend the life of the battery by unplugging it from the main board until 
you are ready to use the computer again.

If the battery ever fails and the CMOS memory is erased the following prompt
is displayed when you turn on the computer.
