OPERATING THE CHARGER
The LED Function Chart below describes the charging process for both the 6amp and 10amp
charger models.

Operating condition
RED
When the red LED is on, it indicates that your battery is discharged and the
battery charger is recharging the battery at the "Bulk" rate (stage 1). This
charging rate is approximately 6 to 10Amps depending on specific charger
model.
While the red LED is on, the battery charger will provide the maximum
charger current rating until the battery voltage reached the maximum bulk
voltage for the selected battery chemistry according to Table 1.
If an excessive amount of time is taken to complete this stage, the charger will
time out and present a fault indicator. (see Troubleshooting Section.)
BLUE
When the blue LED is on, it is charging at the “absorption” rate. (Stage 2).
During this second charging stage, the charger holds the battery voltage at
the specified battery chemistry absorption stage voltage according to Table 1
and gradually reduces the amount of current delivered to the battery.
If an excessive amount of time is taken to complete this stage, the charger will
time out and automatically transition into the “float” stage.
The Intelligent Charging System Series uses the internal micro-controlled
timers to transition the charger output voltage from absorption stage to float
stage to protect the battery from electrolyte depletion. In the float stage the
charger can still supply full output current to battery and external loads.
GREEN
When the green LED is on, the charge cycle is completed and the battery is
ready for use. The optimum replenishment of charge has been returned to
the battery.
The charger will regulate the battery at the nominal float stage voltage
specified in Table 1.
The charger will be able to supply maximum charger output current during this
stage for external DC loads. External DC loads may cause the regulated
voltage to drop, if the battery voltage falls below approximately 12.6VDC, the
charger will automatically restart the charge process.
