  • this product is applicable to the 12V Below 8 0 0AH lead acid  battery ,including maintenance-free,GEL,UPS,wet batteries;
  • Advanced pulse width modulation (PWM) technology is used to automatically charge batteries through a 4-stage charging cycle
  • The battery life can be significantly improved by digital pulse repairing method for the power chips of micro computers
  • Constant voltage charging will be arranged to provide various protections and avoid over-voltage,over-current,over-beating and electrode-positive,ect.
  • When the red indicator light of charging stops flashing or is dark,and as well as the current indicator fell to about 1 bars condition,the charging mode will change to floating charging,means the battery charging being finished.
  • The 12V input when automatic charging mode,Full electric voltage of 13.8V to 14.3V,about 16V input when manual charging mode,must be artificial monitoring in case of overcharge if manual mode charging,suggest stop charging when the battery beating.
  • Do not block cooling hole or use the charger with the cooling fan off.


1,There has strong fan,the speed can be 4500/min;
2,Stable performance,stopped automatic when charge full,pulse auto revive and maintenance battery;
3,Overheating protection:when the temperature of charger is over 105 ° C,the charger will stop working,when the temperature reduce to 80° C or turn off the power 10 minutes the charger can work again;
Short circuit protection:when there has short circuit the charger stopped output and has a beep alert;
4,when the battery single cell voltage is lower than 1.5V the charger can’t start and has a beeb alert,avoid damage battery;
5,when the polarity of charger is adverse with battery,the charger will close automatic and has beeb alert.

The difference between manual and automatic mode

Manual: It can be used for small capacity,Low temperature(under 0 ° C) and large Internal resistancethe battery,charging current is bigger than automatic so it take less time than automatic,but there must has human monitoring to avoid damage battery,when the battery shell has temperature must stop charging!using manual mode can’t more than 1 hour!

Automatic:pulg AC power first then connect battery with charger,it will recognize volgate automatic,telligent and convenient.
Highly recommended:in the winter(under 0 ° C),use automatic mode to charge full first then use manual mode for 0.5-1 hours.
LED screen: it shows both voltage and current, charging Percentage and differnt charging mode with Chinese.
Alligator clips: red is anode,black is cathode
