Preventive Maintenance

• Never expose the battery to direct sunlight or tempera-

tures over 104

°

 F (40

°

 C).

• Always use a Zebra charger designed specifically for Li-

thium-Ion batteries.  Use of any other kind of charger may
damage the battery.

• Choose the media that is easiest to “burn.” An authorized

Zebra re-seller can help you determine the optimum me-
dia 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.

• Pull the battery out of the printer if the printer won’t be

used for a day or more and you’re not performing a main-
tenance charge.

• Consider purchasing an extra battery.
• Remember that any rechargeable battery will lose its abili-

ty to maintain a charge over time.  It can only be re-
charged a finite number of times before it must be re-
placed.

• Don’t print while the LI 72 Wall Charger is plugged into the

unit.  Unreliable battery charging can result.
