be 20V maximum. For severely sulphated batteries, we recommend that the battery is
disconnected from the vehicle.
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 1500mA until the battery
voltage reaches the preset voltage value within 20 hours. if the battery voltage
doesn't reach preset voltage value (14.4V) within 20 hours, the charger will
engage a safety timer protection and RED faulty LED will start flash.
o Absorption Mode (C.V Mode)
 Blue 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 (14.4V) without overcharging.
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.
 The Yellow Charging LED is ON (if above situation occurred)
o Float Mode (Safe voltage level of 13.6V)
 Full Green LED is ON.
 The Float Mode allows the charger to effectively be left connected to your
batteries; it works at a safe level of 13.6V, and ready for use.
o Maintenance mode (Special pulse for long term maintenance)
 Full Green LED is ON.
 The program engages a special charging waveform and monitors the battery
voltage variety, if the battery voltage sinks, the special pulses will keep the
