Machines and Accessories No. 02-08

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.
