February 2010 Digital Talking-Book Player 6
Library Guide
It is estimated that the battery pack will have a service life in excess of 600 charge cycles. Under moderate battery
usage (4 hours per day for 5 days per week), the battery life should exceed 4 years. At the end of its service life the
capacity of the battery pack will be 75 percent of its initial value. A count of the number of charge cycles for the
current battery pack is kept by the player. This may be read by library staff through a diagnostic function.
