6. Pre-charge When batteries are over discharged, bulk charging could damage the batteries. In order to prevent this from happening, pre-charge function will be initiated automatically once the charger detects battery voltage under 10V. When start charging, the charging current is limited to 50% and pre-charge timer will start counting for 30 minutes.
SAFETY INSTRUCTION Misusing or incorrectly connecting the Battery Charger may damage the equipment or create hazardous conditions for users. Read the following safety instructions and pay special attention to all Caution and Warning statements in the guide. Warnings identify conditions that may result in personal injury or loss of life. Cautions identify conditions or practices that may damage the unit or other equipment.

Personal Related Someone should be within range of your voice or close enough to come to your aid when you work near a battery. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
LCD (Digital Meter) DISPLAY GUIDE Item Descriptions O/P Voltage "V": Default display O/P Current, Charging Current "A": The O/P current will display after pressing "Display Key" for 1 second while displaying "V". Press & hold “Display Key” for 3 seconds while displaying “A” to enable O/P current “zero calibration”...

Pulse Charge Diagram (At beginning) Pulse charge at beginning is used to reviving battery when there are many formations of crystals inside the battery and making the batteries unable to be fully recharged. The constant currents charging will knock the crystals into smaller pieces and bring the battery back to life. For the following models, this function can be added upon request: 12Vdc: 10A~30Amp 24Vdc: 7A~17Amp...
BATTERY CHARGING INSTRUCTION A spark near the battery may cause an explosion. Follow instructions carefully to reduce the risk of spark near the battery. Connect the charger system to a wall receptacle strongly. Connect the alligator clips to battery terminals (red clip--->positive terminal; black clip--->negative terminal) For dual output connection, Battery NEG- port is shared for two sets of battery cables Position the AC and DC cords to reduce the risk of damage by a hood, door, or moving engine...
