Operating Manual

• Thank you very much for purchasing our products
• Please use the corresponding model, and the physical object shall prevail
• Please read this manual carefully before use and keep it properly for inquiry when necessary

Charging

1. Check whether your battery parameters match the charger;
2. Clip the output crocodile clips at both ends of the battery, red positive and black negative
3. Insert the charger AC input line into the socket, and then turn on the socket switch
4. Select the mode and select the corresponding charging mode, such as “Car Mode” for car battery, “Motorcycle Mode” for motorcycle battery, “Start-Stop Mode” for starting and stopping power bottle, and then charge.
5. When the charger displays “FUL”, it means that the charging mode has ended. Disconnect the AC input. After 10S, observe the battery capacity status (the panel circularly displays the voltage and the battery power). After confirming that it is full, take off the crocodile clip.

Repair

1. Clip the output crocodile clips at both ends of the battery, red positive and black negative

2. Insert the charger AC input line into the socket, and then turn on the socket switch

3. Press the key to switch to repair mode, and then repair it

4. It is recommended to repair motorcycle batteries for about 5 hours and car batteries for about 8 hours!
   The charger is repaired by default for about 20 hours at a time, and the arrival time will show “FUL” to indicate that the repair mode has ended! Pay attention to the battery temperature when repairing, and stop repairing if the battery overheats!

5. After the repair, disconnect the AC input, and switch the mode key to enter the charging mode at this time to see if it can be charged normally. If it can’t be charged after 1-2 cycles of repair, please replace the battery.

product Functions

1. Output short circuit and anti-reverse connection: the product has the prompt of output short circuit and reverse connection battery (reverse connection 1-2S detection, when reverse connection or short circuit is detected, the panel displays “ERO”, and the product will not be damaged due to reverse connection or short circuit during detection), and when reverse connection is processed by microprocessor program, there will be no reverse connection spark phenomenon;
2. Battery power detection: No AC input voltage is connected, the battery is clamped at both ends of the positive and negative poles of the battery (red, positive, black and negative), which can display the current and voltage parameters of the battery (panel display data: voltage and ambient temperature cycle display, electric grid display in percentage form according to the detected data, self-check waiting for the first power-on for 6S, only display temperature before 6S, and display temperature and voltage cycle display after 6S arrival)
3. Over-temperature protection: The product has the function of over-temperature protection. If the product detects that the temperature is too high, it will start the over-temperature protection program automatically. When the temperature returns to the normal value, it will resume the initial charging state
4. Overcharge protection: The product has overcharge protection function, which can avoid the battery life decline caused by overcharge and enhance the reliability of charging safety (the maximum charging time defaults to 15.5-16.0 H)
5. Battery full charge grid: During the charging process of the product, the battery grid displays the charging progress and the current battery charge, which is displayed at 20%, 50%, 75% and 100%.

Troubleshooting

1. The LCD display “ERO” is checked as follows:
   • Check whether there is reverse connection between the output line and the positive and negative electrodes of the battery. If reverse connection occurs, it will be red, positive and black.
   • Check whether the output lines are short-circuited together. If short-circuited, please disconnect C: A and B have ruled out checking whether the battery is normal. If the battery is normal or this kind of phenomenon occurs, please connect with the after-sales service and do not disassemble the product without permission.
2. The whole display panel flashes. Check as follows:
   • Check whether the battery voltage is lower than 6V. If it is lower than 6V, it is recommended to use repair mode to repair it for a period of time and then charge it when the battery voltage is stable at about 8V. If it cannot be solved, please replace the battery.
   • If the battery is absolutely normal, please contact the after-sales service. Do not disassemble the product without permission.
3. Charger smoke, check as follows:
   • Check whether the charger is sandwiched with batteries above the charging range of the charger, such as batteries above 35V, if they are above 35V, the charger will be damaged.
   • Check whether the AC is plugged into the mains power of 110-240VAC. If it is lower than 110VAC or higher than 240VAC, it may cause damage to the charger.
   • If the above problems cannot be solved, please contact the after-sales service and do not disassemble the products without permission.
4. The charger will be full as soon as it is charged. Check as follows:
   • Check whether the battery is normal. If the battery is vulcanized too seriously and the charge cannot be charged, it will cause misjudgment of the charger. It is recommended to repair it after several processes.
   • Check whether the output clip is in good contact. If there is vulcanized substance on the battery electrode sheet, please clean it and charge it again.
   • If the above problems cannot be solved, please contact the after-sales service and do not disassemble the products without permission.

A Safety precautions

1. Do not charge lithium batteries! It is strictly forbidden to charge scrapped, non-lead-acid batteries or non-voltage batteries! Do not charge non-rechargeable batteries! Do not approach open flames when charging! It is strictly forbidden to disassemble without permission when there is high pressure in the machine
2. Before charging, observe whether the battery is damaged and whether there are abnormal phenomena such as liquid overflow around the battery. If there are abnormal phenomena, please charge carefully;
3. To charge the vehicle or equipment, please remove the battery and charge it in a safe space without flammable items around;
4. When charging, the surface of the battery should not be covered with objects. When charging the battery, it should be erected and placed directly, and it should not be skewed to avoid the surrounding high temperature and high humidity environment;
5. When the charging time exceeds 12 hours and is unattended, the power supply should be cut off. It is strictly forbidden to charge for a long time!
6. Used indoors, beware of rain. During charging, the charger is strictly prohibited from being covered and must be placed in a well-ventilated place. It is strictly forbidden to put it in the car or charge it. Beware of flames, sparks and explosive gases to avoid fire;
