Machines and Accessories No. 02-08 Date: July 26, 2002 Subject: C-1 battery care reminder To enhance battery life, NLS previously recommended a charge-discharge cycle that consisted of charging, unplugging the unit, and running the unit on battery power until the battery was low. Because of improvements in battery technology, this practice is no longer required. Patrons may leave units plugged in as much as they like and use them either plugged in or battery-operated at any time. The unit may be treated like any conventional consumer appliance having rechargeable batteries.
