Preventive Maintenance
Extending Battery Life
• Never expose the battery to direct sunlight or tempera-
tures over 104° F (40° C).
• Do not charge the battery when the temperature exceeds
113° F (45° C).
• Always use a Zebra charger designed specifically for
Lithium-Ion batteries. Use of any other kind of charger
may damage the battery.
• Use the correct media for your printing requirements. An
authorized Zebra re-seller can help you determine the op-
timum media for your application.
• If you print the same text or graphic on every label, con-
sider using a pre-printed label.
• Choose the correct print darkness, and print speed for
your media.
• Use software handshaking (XON/XOFF) whenever possi-
ble.
• Select Tear-Off mode whenever possible (Peel-Off mode
uses more power).
• If your printer has the optional LCD display, use the dis-
play backlight only when necessary. Turn it off whenever
it is not needed.
• Remove the battery if the printer won’t be used for a
day or more and you’re not performing a maintenance
charge.
• Consider purchasing an extra battery.
• Remember that any rechargeable battery will lose its
ability to maintain a charge over time. It can only be re-
charged a finite number of times before it must be re-
placed. Always dispose of batteries properly. Refer to
Appendix D for more information on battery disposal.
• Don’t print while the Model LI 72 Wall Charger is plugged
into the unit. Unreliable battery charging can result.
