BS Charger BK15 Mode D'emploi page 7

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 failed.
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
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 for each channel until the
battery voltage reaches the set value.
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 set value.
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 battery in optimal
state, if the battery voltage drops even lower, the battery charger will switch into Bulk
charging stage. The maintenance mode allows the charger can be connected to the
battery over the course of a season; if possible; check the electrolyte liquid level in the
battery.
STEP 4 - Disconnecting the Battery charger from Battery
 If the Battery is out of the vehicle.
o Switch OFF and Remove the AC Power Socket from the outlet.
o Remove the Black lead and then the Red lead.
o Check electrolyte levels if possible.
(As they may need topping up with distilled water after charging)
 If the Battery is in the vehicle.
o Switch OFF and Remove the AC Power Socket from the outlet.
