Charging Stages
• Soft-Start
is used if a battery’s voltage is under 10.5V when charging
begins. It uses a low constant current to slowly bring up voltage. This
prepares a weak or neglected battery for the Constant Current stage.
• Constant Current
(sometimes called Bulk) is the main charging stage.
The charger puts out a constant current of 2A, 4A or 8A for 12V and 1A,
2A or 4A for 24V, its full power. Battery voltage rises until the battery
reaches the optimal charging voltage.
• Constant Voltage
(sometimes called Absorption) is the second charging
stage. The charger regulates the current given to the battery to maintain
a constant voltage. As the battery nears a full charge, the current
needed to maintain this voltage decreases. Once the current falls below
a 0.10A change per hour, the stage is complete.
• Battery Test
is administered by reading your battery voltage while
resting the battery for 10 minutes. A voltage of under 12.5V indicates a
weak battery, under 11.5V indicates a shorted cell. The battery is tested
at completion of the Constant Voltage stage, and every 12 hours while
in
Float.
• Float
(sometimes called Maintenance) is the charger’s long term stage.
The charger can and should be left connected indefinitely. This will keep
the battery fully charged ensuring no sulfate can form. The charger
maintains float voltage using very little power as it actively monitors the
battery and adjusts its output several times a second.
Indicator Light Details
• Power
light is
GREEN
anytime the charger is plugged into AC Power.
• Battery Connection
light is
GREEN
when the unit it is correctly
connected to a battery. If the
Battery Connection
light is
RED
the
polarity is reversed and the positive and negative terminals need to be
switched. If the light remains
RED
after switching the connections, there
is a short circuit.
• Battery Weak
light is
AMBER
if the
Soft-Start
mode is used or the
battery fails a Battery Test. The indicator will stay on until the battery
passes a Battery Test.
A neglected battery can take over 2 weeks of desulfation to correct. If
after 2 weeks it still reads as a Weak Battery, there is likely internal
physical damage.
• Load
light is
AMBER
if the charger is in Float and outputting 2A. This
indicates a drain on the battery or a large battery that was not charged
within the time limits. If possible remove any loads. When this light is
