Battery Temp Sensor: Simply connect the ring end of one of the enclosed temperature sensor to
a battery terminal post ( negative or positive ) Be sure not to crush the temp sensor which is
enclosed inside the yellow ring terminal, as this will destroy the processor chip. Connect the wire
end of the temp sensor to the connector marked Battery Temp on the Digital Mobile Charge.
Simply push the small lever down and insert one wire into each side. There is no polarity on these
wires. The output voltage will be reduced in the event the battery temperature increases due to
battery failure. If the battery exceeds 50 degrees Celsius, the Digital Mobile Charge will switch off,
as a major battery failure has most likely occurred.
Alternator high temp disengage: This is another supplied temperature sensor which should be
connected to your alternator output post ( b+ ) and will disengage the Digital Mobile Charge in the
event the alternator reaches 100 deg Celsius. A warning LED will illuminate when the alternator
reaches the threshold temperature. When the alternator cools down to 80 degrees Celsius, the
system automatically reengages and continues charging.
Battery Charging Voltage Monitoring: As a standard feature, this unit senses all the control
voltages at the unit. However, if you want to sense the voltage at the domestic battery bank
directly to overcome the voltage drop in the cable run, then simply connect a cable from the
domestic sense connection directly to the domestic battery.
Positioning Battery Type Selector Switch:
Program the battery type into the unit. Do so by positioning the battery type dip switches on the
unit to the appropriate battery type.
There are 4 possible battery type selections:
1) Non-Sealed Lead Acid Battery (Orange LED)
2) Exide Gel Battery (Green LED)
3) Gel Battery (All others except Exide) (No LED)
4) AGM Battery (Red LED)
Understanding Battery Types
There are three primary types of batteries in the marketplace today; Flooded (Lead Acid), AGM (Absorbed Glass Mat)
and GEL cell (Gelled Electrolyte Lead-Acid). Traditionally, the most common type of batteries used are Flooded (Lead
Acid batteries).
Almost all GEL cell batteries will state that they are GEL cell on the battery case or labels. (Shown below) are typical
battery voltages at absorption and float levels.
***If you are still unsure as to what kind of battery you have, we recommend that you contact the manufacturer of the
battery.

NOTE: AGM (Absorbed Glass Mat) batteries are not GEL (Gelled Electrolyte Lead-Acid) batteries. AGM
batteries are charged at the same charging profile as Flooded (Lead Acid).
