 Danger of explosive gases

1. Working near the acid battery is dangerous as the battery may release explosive gases during normal operation. Thus, it becomes the most important to use the charger according to the operation instructions.
2. To reduce the risk of battery explosion, please follow these instructions and those published by the car battery manufacturer and manufacturer of any equipment you intend to use in the vicinity of the battery.

 

Safety Features

Floating mode automatically turns on

The charger will enter floating mode to prevent overcharging when the battery is fully charged.

DC output short circuit protection:

The charger will stop output automatically when the DC output clips short circuit.

Overheat protection:

The charger will enter overheat protection mode automatically when the internal temperature reaches the pre-set temperature limit, or if the charger is used in a high environment temperature for a long time. When the temperature is reduced to a normal level then the charger will enter charging mode automatically.

Fire protection:

To avoid sparks, no output should pass through the clips when you disconnect the battery.

Low voltage starting:

The charger will enter charging mode automatically if the voltage of clamps is higher than 1.5V DC. No output will pass through the clips if the voltage is lower than 1.5V DC.

Operation

 

Charging a single separate battery

1. Connect the AC plug to an AC power outlet.
2. Select the correct charging mode first, then connect the red clamp/O ring to the positive terminal of the battery “+”, connect the black clamp/O ring to the negative terminal of the battery “-”.
3. Please remove the plug from the AC socket before disconnecting the battery and then remove the clamp/O ring from the battery.

 

Charging car battery

1. Connect the AC plug to an AC power outlet.
2. Select the correct charging mode according to the car battery’s rated voltage and battery type and then press the Enter/Exit button to start charging. To change charge mode, just press the Enter/Exit button again to re-select the mode.
3. Please remove the plug from the AC power outlet before disconnecting the battery.
4. Disconnect the black clamp and then disconnect the red clamp. If the car battery is positively grounded, first disconnect the red clamp and then disconnect the black clamp.

Charging Step Instructions

 

Desulphation:

Detecting vulcanised batteries, then remove sulphur from the lead plates of the battery by pulsing current and voltage.

1/2 Constant current:

Charging the battery to 25% of capacity with 1/2 current.

Constant current:

Charging battery to 50% capacity with the maximum current.

Constant voltage:

Charging battery to 75% capacity with constant voltage.

Analysis:

Analysing power capacity, if the battery cannot store power, then the battery should be replaced.

Record:

Restores power capacity in a stratified battery to sustain ultimate battery life.

Float charge:

Charging battery to 100% capacity with a small current.

Diagnosis:

To check whether the battery is fully charged.

Maintenance:

The charger will use a small current to keep the battery fully charged.

Troubleshooting

 

Fault phenomenon	Troubleshooting
When connected there is no reaction	1. Check if the product is effective when plugged into the socket 2. Check whether there is electricity on the AC socket
The icon flashes all the time	3. Check if the clamp is effective when connected 4. Check whether the positive and negative terminals of the battery are vulcanised and cause poor contact 5. Check whether the DC clamp wire is broken
The icon is always on	6. The clamps are reversely connected to the positive and negative terminals of the battery
The charging mode cannot be switched, or the switch button is insensitive	7. The switch has not been used correctly. 8. The switch may be damaged 9. Please check the charger, to check whether it is connected to the battery. Mode needs to be changed while not connected.
