In this case, please contact your local dealer and have the battery tested.

PRODUCT AND ACCESSORIES

FOUR-STAGE CHARGER

• Stage 1: Desulfating the battery through 18V pulse. The charger enters this stage if it detects battery sulfation or severe discharge. Once the battery is rejuvenated, the charger moves to the Bulk stage (LEDs: 1 ON, 2-4 OFF).
• Stage 2: Bulk charge using the charger’s highest rated current for the type of battery in use until it reaches 80% capacity (LEDs: 1-4 Blinking Sequentially).
• Stage 3: Absorption, the output voltage is limited to 14.7V while current declines as the battery charges to its full capacity without overheating (LEDs: 1-3 ON, 4 Blinking).

• Stage 4: Float, at this stage, the battery is fully charged and the charger maintains the battery through pulse charging (LEDs: 1-4 ON).

  

Note: Do not turn your battery charger on and off repeatedly (plug and unplug) within a short period. If this happens, unplug the battery charger from AC power, wait for one minute, and then connect the charger again to restart the charging cycle.

HOW TO USE

1. Connect the AC cord to the socket. The "POWER" LED (red) will light solid.
2. Connect the red clip to the positive battery terminal and the black clip to the negative terminal. Depending on the battery capacity and charging time, the "25%~100%" LEDs will light in sequence.

3. When the lights are ON, it indicates the battery is fully charged. You can disconnect manually, or it will automatically switch to float mode.

   

NOTICE: If the battery polarity is reversed or the output is shorted, the fault light will flash. Please DISCONNECT & CHECK.

WARNING - RISK OF EXPLOSIVE GASES

PREPARING TO CHARGE 

• If necessary to remove the battery from the vehicle to charge, always remove the grounded terminal from the battery first. Make sure all accessories in the vehicle are off to avoid causing an arc. 
• Ensure the area around the battery is well ventilated while charging. 
• Clean battery terminals. Be careful to keep corrosion from contacting your eyes. 
• Add distilled water in each cell until the battery acid reaches the manufacturer’s recommended level. Do not overfill. 
• Study all battery manufacturer’s specific precautions such as removing or not removing cell caps while charging and recommended rates of charge. 
• Determine the voltage of the battery by referring to the car owner’s manual. Do not charge the battery unless the voltage matches the output voltage rating of the charger.

CHARGER LOCATION 

• Never place the charger directly above the battery being charged; gases from the battery will corrode and damage the charger. 
• Never allow battery acid to drip on the charger when reading electrolyte specific gravity or filling the battery. 
• Do not operate the charger in a closed-in area or restrict ventilation in any way. 
• Do not set a battery on top of the charger.

DC CONNECTION PRECAUTIONS 

• Connect and disconnect DC output clips only after setting any charger switches to the off position and removing the AC cord from the electric outlet. 
• Position AC and DC cords to reduce damage by hood, door, or moving engine parts. 
• Stay clear of fan blades, belts, pulleys, and other parts that can cause injury. 
• Check the polarity of battery posts. The POSITIVE (POS, P, +) battery post usually has a larger diameter than the NEGATIVE (NEG, N, -) post. 
• Determine which post of the battery is grounded (connected) to the chassis. If the negative post is grounded to the chassis (as in most vehicles): 
• For a negative grounded vehicle, connect the POSITIVE (RED) clip to the POSITIVE (POS, P, +) ungrounded post of the battery. 
• Connect the NEGATIVE (BLACK) clip to the vehicle chassis or engine block away from the battery. Do not connect the clip to the carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine block. 
• For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the battery charger to the NEGATIVE (NEG, N, -) ungrounded post of the battery. Connect the POSITIVE (RED) clip to the vehicle chassis or engine block away from the battery. Do not connect the clip to the carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine block. 
• When disconnecting the charger, disconnect the AC cord, remove the clip from the vehicle chassis, and then remove the clip from the battery terminal.

O-RINGS ADAPTER PRECAUTIONS 

• Must be used in conjunction with the charger. Accessory wires used for other purposes may cause fire or short circuit. 
• Ensure that the terminal is in good contact with the battery or charger, and the insulation cover is not detached or damaged. 
• Ensure that the ring connectors are in good condition (no damage or bare copper) before use. 
• The fittings and wires are prone to aging, do not touch any chemical liquids, and check the insulation of the wire regularly. If they are aging, replace them promptly. 
• Do not leave the ring connector connected to the battery if not in use, or it may cause fire or short circuit when using the battery in your vehicle.

FOLLOW THESE STEPS WHEN THE BATTERY IS OUTSIDE THE VEHICLE. A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. 

TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY

• Check the polarity of battery posts. The POSITIVE (POS, P, +) battery post usually has a larger diameter than the NEGATIVE (NEG, N, -) post. 
• Attach at least a 24-inch-long 6-gauge (AWG) insulated battery cable to the NEGATIVE (NEG, N, -) battery post. 
• Connect the POSITIVE (RED) charger clip to the POSITIVE (POS, P, +) post of the battery. 
• Position yourself and the free end of the cable as far away from the battery as possible, then connect the NEGATIVE (BLACK) charger clip to the free end of the cable. 
• Do not face the battery when making the final connection.
• When disconnecting the charger, always do so in reverse order of the connecting procedure and break the first connection while as far away from the battery as possible. 
• A marine (boat) battery must be removed and charged onshore. Charging it on board requires equipment specially designed for marine use.
  • Children should be supervised to ensure that they do not play with the appliance.
  • This appliance is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

DEFECTIVE BATTERY RECOGNITION

If your battery is totally discharged (Below 3 volts), the battery charger circuitry will not start due to its internal safety circuit. The fault light will turn on, and the charger will return to standby mode.

NOTE: Unless the battery was rapidly discharged (lights left on overnight), most 12-volt lead acid batteries that are at a state of charge that is less than 9 volts are likely to be worn out or defective.

TROUBLESHOOTING

2 STEPS TO DETECT THE CHARGER

1. No-Load Test 
   Connect the AC plug of the charger into power to observe the power light. 
   If the power light turns red instantly, the 25%-100% lights flashing in sequence, and the power light stays on, then the charger is normal.
2. Short Circuit Test 
   Connect the AC plug of the charger into power. 
   Connect the positive and negative clip to each other to observe the fault light. 
   If the fault light is flashing, then the charger is normal.

Tips: If the indicator light does not perform as described in these two steps, the charger might be defective. Please contact us to solve your problems.
