• Remove the charger's positive terminal clamp (red) 13 from the battery's positive terminal.

Select Charging Mode

You can choose between different charging modes for various batteries and ambient temperatures. Unlike standard chargers, this appliance has a special function to reuse empty batteries. It can recharge completely discharged batteries. Protection against incorrect connection and short-circuiting ensures safe charging. Due to the installed electronics, the charger only starts operation after a charging mode has been selected, preventing sparks that often occur during connection. The charger is controlled by an internal MCU (micro-computer unit).

Reset/Deleting Settings

After connecting to the power supply, the appliance automatically returns to its initial state and remains in Standby mode.

Switching Between Modes 1, 2, 3, and 4

Press the "MODE" selection button 9 repeatedly. The appliance cycles through modes in the following order: Standby (?), Mode 1 (6V), Mode 2 ( ), Mode 3 ( ), Mode 4 ( ), and then restarts the cycle.

NOTE: If you press the "MODE" button 9, the charging mode automatically switches to the next mode and begins operation. If a 12V battery is connected, Mode 1 (6V) is not selectable. If a 6V battery is connected, Modes 2, 3, and 4 are not selectable. If a fully charged battery is not disconnected, the appliance remains in trickle-charge mode, protecting the battery.

Mode 1 "6 V" (7.3 V/0.8 A)

Suitable for charging 6V lead-acid batteries with a capacity below 14 Ah.

• Press the "MODE" button 9 to select Mode 1 (6V). The corresponding "Mode 1" LED 1 lights up. If no further action is taken, the electronics activate with the "Charging" LED 7, starting the charging process.
• If the procedure is successful, the "Charging" LED 7 remains lit until the battery is fully charged to 7.3 V/± 0.25 V. The "Fully charged" LED 6 then lights up, and the "Charging" LED 7 turns off. The appliance automatically switches to trickle charging mode.

Mode 2 "12 V" (14.4 V/0.8 A)

Suitable for charging 12V lead-acid batteries with a capacity below 14 Ah.

• Press the "MODE" button 9 to select Mode 2 ( ). The corresponding "Mode 2" LED 2 lights up. If no further action is taken, the electronics activate with the "Charging" LED 7, starting the charging process.
• If the procedure is successful, the "Charging" LED 7 remains lit until the battery is fully charged. The "Fully charged" LED 6 then lights up, and the "Charging" LED 7 turns off. The appliance automatically switches to trickle charging mode.

Mode 3 "12 V" (14.4 V/3.8 A)

Mainly for charging 12V lead-acid batteries with a large capacity (over 14 Ah) under normal conditions.

• Press the "MODE" button 9 to select Mode 3 ( ). If no further action is taken, the electronics activate with the "Mode 3" LED 3, starting the charging process.
• If the procedure is successful, the "Charging" LED 7 remains lit until the battery is fully charged. The "Fully charged" LED 6 then lights up, and the "Charging" LED 7 turns off. The appliance automatically switches to trickle charging mode.

Mode 4 "12 V" (14.7 V/3.8 A)

For charging 12V lead-acid batteries with a capacity over 14 Ah in cold conditions, or for several AGM batteries over 14 Ah.

• Press the "MODE" button 9 to select Mode 4 ( ). If no further action is taken, the electronics activate with the "Mode 4" LED 4, starting the charging process. The charging current is the same as in "Mode 3".
• If the procedure is successful, the "Charging" LED 7 remains lit until the battery is fully charged. The "Fully charged" LED 6 then lights up, and the "Charging" LED 7 turns off. The appliance automatically switches to trickle charging mode.

Automatic Battery Recognition

As soon as the charger is connected to the mains, the LED display lights up. The charger recognizes the battery based on the following criteria:

• If the battery voltage is less than 3.8V or greater than 15V, the battery is unsuitable or defective. The "6V", "Mode 2", "Mode 3", and "Mode 4" LEDs ( 1, 2, 3, 4) flash. The charger remains in "Standby mode" and cannot be switched to another mode using the "MODE" button 9.

Pulse Charging Mode

This mode is suitable for charging/regenerating empty, used, and overcharged 12V lead-acid batteries. When connected to a battery, the charger automatically recognizes the battery voltage and switches to pulse charging mode if the voltage is between 7.5V ± 0.5V and 10.5V ± 0.5V. This process continues until the battery voltage reaches 10.5V ± 0.5V. The charger then switches back to the previously selected normal charging mode. This procedure allows quick and safe charging and can regenerate most batteries.

NOTE: During pulse charging, the "Charging" LED 7 flashes.

Trickle Charging

The charger has an automatic trickle charging function. Depending on the battery voltage, it supplies different charging currents. The battery can remain connected for extended periods.

Protective Function of the Appliance

In case of abnormal situations like short circuits, critical voltage drops, open circuits, or reversed polarity of output terminals, the charger deactivates its electronics and returns to its initial state to prevent damage. If no other setting is made, the system remains in Standby mode. Incorrect terminal connection (reverse polarity) will light up the "Error" LED 5. If the appliance overheats during charging, the output power is automatically reduced to protect it.
