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:
o Soft start Charging Mode (C.C. Mode)
 Blue Charging LED is flashing.
 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.
o Bulk Charging Mode (C.C. Mode)
 Blue Charging LED is ON.
 The battery can be charged about 80%.
 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.
o Absorption Mode (C.V Mode)
 Green absorption charging LED is ON.
 The battery can charge up to almost 100%.
 The charging current tapers and the charging voltage are kept constant at the
preset value without overcharging.
o Equalization charging
 Blue Bulk LED and Green Equalization LED both flashing.
 A well proven process that carefully equalize the battery to store it’s full
capacity, the Equalization stage for Calcium 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.
o Analysis Mode ( Battery retention test Mode)
 The charging is interrupted for a short period for battery voltage measured
 If the battery voltage falls too quickly, the battery is probably faulty.
