Lithium battery

Neo contains a secondary backup battery that isn't intended to be
accessed by users. The lithium battery provides power to the memory
and prevents data loss when the unit is turned off or when the
batteries are dead or removed. The lithium battery will last
approximately five to seven years. If you suspect a problem with the
lithium battery, visit the AlphaSmart web site for more information
or contact Technical Support for assistance.
