Automatic repair

Please select "Automatic repair"

"Automatic repair" allows you to connect the charger to your battery (either in or out of the vehicle) and forget about it until you are ready to put the battery to work. Like all Battery chargers, once the battery has reached a 100% charge the "Automatic repair" automatically switches it's output voltage to a safe, storage/float level that eliminates the need to worry about the damaging effects of overcharging. If/when the battery Voltage drops too far under load, output power will begin again bringing you battery back to a fully charged state.

This model 618D power charger is specially designed and manufactured for 12V/24V lead-acid, dry batteries, water batteries, lead-acid maintenance-free batteries, lithium batteries . （Battery Capacity:6-400Ah） The nominal theoretical current is: 12V-20A(max), 24V-15A(max). Please ensure the output of the charger is the same voltage as your battery.

NOTE

Only used charger "Manualrepair" for in emergency situations!!! MUST be disconnected after the "Manualrepair" is fully charged, Otherwise it will damage the battery.

Charging operation

Step 1, Examine and make sure rated voltage of battery is conforming to output voltage of charger. Step 2, Connect correctly the charger and the battery. Step 3, Examine and make sure mains supply voltage is conforming to input voltage of the charger. Step 4, Connect mains supply and the battery, watch to see if the indicator is on and the cooling fan is working when charging. Step 5, if the charger refuse to work, turn off mains supply immediately and check all the connecting cables between mains supply, the battery and the charger.

5-Stage Mode

No-load Mode when there has no load connected with charger,the LED Screen will show voltage only,the power is about 2W; Constant Current means the battery voltage is lower than the set voltage of charger,then the charger supply constant charging current to maintenance both battery and battery charger; Constant Voltage advanced pulse width modulation (PWM) technology,control the charger's current and output voltage accurate,avoid overcharge; Floating charge when the battery is going to be charged full,the charger will stop charging,but still supply constant floating voltage and small current to battery; Trickle charge when the battery voltage and current is approaching the set voltage and current,it will turn to trickle floating charge from automatic mode,it means charge full,also can be charged with floating mode.
