7. Output Connector : DC jack, XLR, JST, Cigar Lighter, Alligator Clips etc

Advantage :

1. full automatic transition of cc cv and float/ cut-off (cc cv 3 stage charger)

2. Precise limit of voltage& current, guarantee fully charged and avoid over charger

3. Protections : short circuit, over voltage, over-temperature, reverse polarity protections, Dc output isolated from AC input

4. High Efficient : > 85% PFC :0.96 Eco-friendly

5. Two led indicators LED1 Red ( power on ), LED 2 Red/Green ( charging/full )

6. Safety and high quality, Advantage high frequency switching mode power supply technology.

The 3-stage mode charging : 

First stage ( constant current ) : The charger will supply constant current for the battery
 
Second stage ( constant voltage ) : The voltage will be rising under the first stage, when it reach constant voltage value, it will turn into the second stage. The current will be slowly smaller until it reduce to floating value,the CV stage will end.
 
Third stage ( Floating charging ) : When the current is approaching the value of transition, the charger will cut down to the given current gradually, that means the battery power is full and indicator light turn to green. At this moment, the battery can be stopped charging or keep on trickle current charging for half an hour.

Charging Procedure :
1.First output power charger wire ends are connected to the battery anode and cathode , the charge indicator turns green, the connection is correct, otherwise the charge in question, please check the actual situation.
2.Then city power plug to socket , the indicator is red, charger will be into the charging state .
3.When the indicator light turns to green, the battery is charged to 95% , If you want to reach 100% , keep charging for 1 to 2 hours before end of charge.
4.When fully charged, disconnect the city power first, then disconnect the battery cable.
