Battery
"
NOTE:
You
must
charge your Mobile Computer for at least 4 hours before
you use it the first time. This is to ensure that the main pack, and if
equipped with a radio battery, are fully charged.
The 700 Series Mobile Computer uses a 1800 mAh Lithium
Ion rechargeable battery. The computer will automatically
monitor the battery power level. When the battery reaches
30% of full capacity, your computer will blink the red Low
Battery LED.
A number of conditions affect how long your mobile
computer operates before going into low battery. Conditions
such as, scanning, time the backlight remains on, the
temperature you are using your mobile computer in, and
radio activity greatly affect operational hours.
Temperatures at both extremes will reduce operation time
and battery life.
Cold Temperatures
Cold temperatures significantly reduce the run down time.
Just like in an automobile, the “cold cranking amps” or the
energy available at cold temperatures is reduced. For
Lithium batteries, the energy available at --4
d
F (--20
d
C)
may be only 20--40% of the energy available at 68
d
F (20
d
C).
