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 not connected, after 10 seconds, the charger will automatically go into ECO mode.
• The Green LED is fast flashing indicates the ECO mode.
BATTERY INITIAL QUALIFICATION
When the battery is connected and ac powers on, the program will automatically run qualification as the following processes:
- Detects the battery internal impendence and initial voltage.
- Determine the charging rate acceptance.
- Diagnoses the battery sulphated condition.
ENHANCED BATTERY REJUVENATION
If the initial qualification detected that the battery was in poor condition, our unique rejuvenation process
(patented in USA 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, balance out the high concentrations of acid, which is to extend
your battery life and performance.
If the battery voltage does not reach 9V within 24 hours, the Rejuvenation process will be timed out.
• The Blue LED is flashing indicates the Rejuvenation stage.
If the program detects the battery can be normally accepted charging current, it will directly go into Soft start stage;
if the battery still can not accept the charging current after 24 hours rejuvenation, it expresses the Battery Rejuvenation
fails and the battery is not healthy.
• The Red LED will be ON to indicate the battery rejuvenation failure.
SMART CHARGING MODE
There are 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 will engage a safety timer protection and RED faulty LED will start flash.
•
Bulk Charging Mode (C.C. Mode)
ƒ Blue Charging LED is ON.
ƒ The battery can be charged about 80%.
ƒ The charger delivers an almost constant current of the maximum output until the battery voltage reaches
the preset voltage value within 24 hours, if the battery voltage doesn’t reach preset voltage value within 24 hours,
the charger will engage a safety timer protection and RED faulty LED will start flash.
•
Absorption Mode (C.V Mode)
ƒ Green absorption charging LED is ON.
ƒ The battery can charge up to almost 100%.
ƒ The charging current tapers and the charging voltage are kept constant at the preset value without overcharging.
•
Equalization charging
ƒ Blue Bulk LED and Green Equalization LED both flashing.
ƒ A well proven process that carefully equalize the battery to store it’s full capacity, the Equalization stage for Pure Lead
battery selection is automatic. The equalization stage for AGM & WET and GEL battery only occurs if the in Initial start
voltage is below 11 Volts.
