Operation Instructions :
1.To check if your local power supply conformsto charger input voltage 110 or 230V,then connect the charger system to a wall socket , if charger has switched to OFF position ,it must be set to ON status .
2.LED1 (RED ) confirms AC power on an LED2 Green confirms if the charger connects well or not
3.Connect the plug or the DC output cord to battery terminals ,it indicates the charger is charging the battery when the red light turns on ,and
the battery will be fully charged when the battery was charged fully .
Notes : if the charger with a Relay for reverse polarity prouction , it does not have output voltage and current when the Charger AC power on
but disconnecting with the battery , it will have voltage an current output when it connects with battery , if the charger has a fuse instea of Relay
for reverse polarity protection , it has output once AC power on .
Precautions 
1. the phenomenon of sparking is normal when it connects to the battery because of high current
2. This charger is designed for charging lithium tupe batteries only
3. Avoid charging the wrong type battery
4. Always place the charger in well-ventilated and dry environments
