3.6 Back-up Battery
The Antares SB
TM
offers the possibility of a built-in back-up Lithium-
Polimer battery to be used whenever the main power source (the ve-
hicle’s battery) is lost or sabotaged.
Not all of the units come with the built-in back-up battery, contact
Digital Communications Technologies
TM
or your dealer and ask for
information.
Warning:
The duration of the back-up power depends on many factors like:
•
Frequency of the unit’s reporting.
•
Network conditions: Poor network signal demands more power
from the unit.
• Battery condition: At full charge, mid-charge, etc.
•
Unit working on the sleep or normal mode.
Having the back-up battery at full charge on good network conditions
the measured durations are:
•
10 hours at full rate GPRS transmission: Having the unit re-
porting to an IP-type destination on a 10 seconds basis.
•
10 days when in sleep mode: Only inputs’ detection is available
and an optional wake-up interval is available. This last wake-up
option was not used on the battery test.
The battery level measurement is done in a similar way as the unit’s
Analog to Digital Converter please refer to that section for some
notes.
