• Read these instructions carefully before using the charger.
• Only use the charger for its intended purpose.
• Connect the charger to a suitable power source, according to the specifications on the device label.
• The charger contains dangerously high voltage, so contact the manufacturer in the event of equipment failure.
• Avoid using the charger in high humidity, high temperatures or near flammable or explosive materials.
• Do not block the ventilation holes or use the charger when the cooling fan is not working.
• Do not leave the charger unattended during use.
• Protect the unit from rain and water to avoid damage.
• Persons without the appropriate qualifications must not open the device or change its purpose. This can lead to serious injury.
• Check that the battery parameters are compatible with the charger.
• Connect the red terminal to the positive (+) terminal and the black terminal to the negative (-) terminal. Select the correct type of battery.
• Connect the charger to an AC power source, and the charger will start working. The charging indicator will start flashing in color, indicating that the charger is operational.
• The current drops below 0.3A (or below 0.5A).
• The charging indicator is off.
• The display shows 100% on the CHARGER screen.
• Select the appropriate battery type and press the maintenance button to start. When maintenance is complete (approximately 1 hour), it will automatically switch to smart charging and stop when the battery is full.
• To assess the condition of the battery, compare the accumulated charge with its original capacity:
• Cumulative charging > 25% of battery capacity: The battery is in good condition.
• Cumulative charging < 25% of battery capacity: The battery has poor energy storage capacity, and replacement is recommended.

Note: For a 100Ah battery, after a full charge cycle, the cumulative charge should be at least 25Ah for efficient battery operation.

BATTERY CHARGING

1. Check that the battery parameters are compatible with the charger.
2. Connect the red terminal to the positive (+) terminal, and the black terminal to the negative (-) terminal. Select the correct type of battery.
3. Connect the charger to an AC power source and the charger will start working (the charging indicator will start flashing in colour. This indicates that the charger is starting to operate.

HOW DO YOU KNOW WHEN THE BATTERY IS FULLY CHARGED?

1. current drops below 0.3A (or below 0.5A)
2. The charging indicator is off
3. display “100%” on the CHARGER screen.

Note: For normal batteries, if the battery is abnormal, simply refer to the first point.

HOW TO USE THE MAINTENANCE (REPAIR) MODE?

• First, select the appropriate battery type and then press the maintenance button to start. When maintenance is complete (it takes about 1 hour), it will automatically switch to smart charging. It will stop when the battery is full.

INFORMATION ON CUMULATIVE CHARGING

• To assess the condition of the battery, the accumulated charge is compared with its original capacity
• Battery performance evaluation:

Cumulative charging > 25% of battery capacity:	The battery is in good condition
Cumulative charging < 25% of battery capacity:	The battery has poor energy storage capacity, and replacement is recommended.

• For a 100Ah battery, this means that the cumulative charge after a full charge cycle should be at least 25Ah in order to be considered an efficient battery.

PROBLEM SOLVING

RECHARGING TIME

• If the battery capacity is greater than 105 Ah, it can also be charged, but the charging time will be relatively increased.
• The above charging data is an actual reference to charging in the normal state of the battery.
