SECTION 2 : OPERATION PROCEDURE 

2.1 

Ensure the type and output voltage before power 
on. 

 
2.2 

Connect charger-line (accessory) with +/- terminals. 

 

Warning : +/- terminals should not be shorted ! 

 
2.3 

Plug  in  then  switch  on,  voltage  meter  should  be 
read by 13.8V (12V) / 27.6V (24V). 

 
2.4 

If output voltage correct then power off. Connect 
the red side of the charger-

line to the “+” terminal 

of the battery, the black one to the “

” terminal. 

 
2.5 

Power  on  then  charging  is  starting,  the  more 
charge  current  the  less  time  needed,  current  is 
adjusted by current-adjust-knob on the panel. For 
the  long  time  charging,  we  suggest  the  current 
less than 1A. 

 
 
 
 
2.6 

Factory  setting  of  output  voltage  is  13.8V  or 
27.6V,  on  the  conditon  of  old  batteries  the 
voltage can be boost by turning the VR from the 
hole located on the panel. 

 

 

CAUTION  !!

  High  voltage  will  cause  batteries 

liguid vaporized and batteries damaged. 

 
2.7 

Our  charger  has  voltage-feedback-sensor  to 
avoid  batteries  be over-charged,  if the  battery  is 
full charged then output current will be reduced to 
zero, in order to extend the life of the battery.
