Mode 2 Charging:
The Two-Stage mode 2 charging is similar to the Three-Stage charging except that there is no
Float
stage after the
Absorption
stage. The charger will terminate the battery charging after Absorption
stage.
The charger will automatically restart the full charging cycle if it senses any one of the battery banks
is discharged to lower than 12.5V for the 12V model, 25.0V for the 24V model, or after seven days
since the last Absorption stage to refresh the battery banks.
Understanding the Battery Temperature Set Functions:
For use when Battery Temperature Sensor is
NOT
in use:
CAUTION: RISK OF BATTERY DAMAGE.
If the temperature sensor is not being used, never set
the battery temperature lower than the actual temperature. This may
overcharge and damage
the
batteries.
There are three manual battery temperature settings available on the unit for GEL, Flooded and
AGM batteries.
•
Low temperature ‘Lo’, setting for when the battery is charging in a low temperature environment.
•
Normal temperature ‘nor’, setting is for when the battery is charging at room temperature.
•
High temperature ‘HI’, setting is for when the battery is charging in a high temperature
environment.
With different settings above, the battery charging voltage is adjusted as listed below.

For use when Battery Temperature Sensor is in use:
No setting on the unit is required, and the unit will automatically sense the Battery Temperature
Sensor when it is connected to the BTS Port and the manual battery temperature setting on the unit
will be over-ridden by having the Battery Temperature installed.
•
Use with GEL, AGM, or Flooded Battery Type Setting:
The battery sensor installed on Battery Bank 1 will monitor the Battery Bank 1 battery
temperature and will make small adjustments to the battery charging voltage on CH1 for better
battery charging performance.

The sensor is also used to terminate the battery charging process when the battery temperature
drops to below -25°C and the charging process will resume again when battery temperature rises
to above -20°C. It will also terminate the charging process when the battery temperature rises to
above 70°C and the charging process will resume again when the battery temperature drops to
below 60°C.
•
Use with Lithium or Program Setting:
The battery sensor installed on Battery Bank 1 will monitor the Battery Bank 1 battery
temperature. It is used to terminate the battery charging process when the battery temperature
drops to below 0°C. The charging process will resume again when battery temperature rises to
above 5°C. It will also terminate the charging process when the battery temperature rises to
above 60°C and the charging process will resume again when the battery temperature drops
to below 55°C.
