USER’S MANUAL
THE CHARGING PROCESS
The charging stages and performance are as follows:
ECO Mode
If AC power is connected and the battery is disconnected, after 10 seconds the charger will automatically go into ECO mode.
• The green LED flashes quickly to indicate ECO mode.
Qualification – Battery Condition Analysis
When the battery is connected and AC power is on, the program will automatically run a battery condition check:
- Detects the battery’s internal impedance and initial voltage.
- Determines the charging rate acceptance.
- Checks for battery sulphation.
- Senses whether the battery is still connected to the vehicle’s electronic circuit.
The program will determine the next stage according to the results of this initial qualification.
• The red LED is ON and the yellow LED is ON (the initial voltage is very low).
Enhanced Battery Rejuvenation
If the initial qualification detected that the battery was in poor condition, our unique rejuvenation process (patented in the US and
Europe) will begin automatically. During the rejuvenation process, a high voltage equalizing and peak pulse reconditioning charge
is used to repair the sulphated battery. This unique patented feature will break down and dissolve the lead-sulphate crystal built up
on the battery plates, and balance out the high concentrations of acid, which will extend your battery life and performance.
• The blue LED flashes to indicate the rejuvenation stage.
Manual enhanced rejuvenation mode serves to manually rejuvenate your batteries. Simply press and hold the Battery Type button
for 3 seconds until the blue Bulk LED flashes rapidly. This mode lasts for 24 hours. To interrupt rejuvenation mode, press and hold
the Charge Mode button for 3 seconds until the blue Bulk LED stops flashing rapidly.
If the program detects that the battery can accept a normal charging current, it will directly enter the Soft Start stage; if the battery
still cannot accept the charging current after 24 hours of rejuvenation, battery rejuvenation has failed and the battery is not healthy.
• The red LED will be ON to indicate battery rejuvenation failure.
Smart Charging Mode
Includes the following stages:
• Soft Start Charging Mode (C.C. Mode)
ƒ Blue charging LED is flashing.
ƒ Gently ramps up the battery voltage to 11V. If the battery voltage doesn’t reach 11V within 6 hours, the charger’s
safety timer protection will kick in and the RED faulty LED will start flashing.
• Bulk Charging Mode (C.C. Mode)
ƒ Blue charging LED is ON.
ƒ The battery can be charged about 80%.
ƒ The charger delivers a near-constant maximum charge current output. If the battery voltage doesn’t reach the preset voltage
value within 24 hours, the charger’s safety timer protection will kick in and the faulty LED will start flashing.
• Absorption Charging Mode (C.V. Mode)
ƒ Green absorption charging LED is ON.
ƒ The battery can charge up to almost 100%.
ƒ Uses a constant voltage while reducing the charging output
current
to ensure the battery receives a full charge
without overcharging the battery.
• Equalization Charging
ƒ The blue bulk LED and green Absorbtion LED are both flashing.
ƒ A proven process that carefully equalizes the battery to restore its full capacity.
The Equalization stage for Calcium batteries is automatic.
The Equalization stage for AGM, WET, and GEL batteries only occurs if the initial start voltage is below 11V.
