Frequently Asked Questions - ALCT6-24/10 ANSMANN

How to connect the charger to the battery?

First connect the red cable to the positive (+) terminal of the battery, then the black cable to the negative (-) terminal. Then plug the charger into the mains. To disconnect, reverse the order: first unplug the mains plug, then the black cable, then the red cable.

What to do if the clamps are reversed?

The charger emits an audible signal and the red LED lights up. Immediately disconnect the charger from the mains, then reconnect the clamps respecting the polarities (red on +, black on -).

What is the 'COLD TEMPERATURE' mode?

This mode is recommended when the ambient temperature is below 5 °C. It increases the charging voltage (e.g., 14.9 V for a 12 V battery) to compensate for the effects of cold and allow full charging. To activate it, press and hold the MODE button for 3 seconds.

What is the 'REGENERATION' (REFRESH) mode?

This mode starts automatically if the battery is deeply discharged (voltage below 5 V for 6 V, 10 V for 12 V, 20 V for 24 V). The charger applies a pulse charge to reactivate the battery before switching to normal charging.

How to read the charge status indicator?

Three LEDs indicate the level: 35% flashing: 0-35%; 35% solid + 70% flashing: 36-70%; 35% and 70% solid + 100% flashing: 71-100%; all solid: battery fully charged.

What does the 'FAULT' display mean?

The charger displays FAULT and stops charging if the battery is considered defective (e.g., internal short circuit, broken cell). Disconnect the charger and check the battery; replace if necessary.

Can I charge a frozen or damaged battery?

No. Never charge a frozen or damaged battery, as this may cause explosion or burns. Check the battery condition before charging.

Which charging current to choose for my battery?

The charger offers 1 A, 5 A and 10 A. Recommendation: 1 A for capacity < 20 Ah, 5 A for 20-40 Ah, 10 A for > 40 Ah. Use the MODE button to adjust.

Can I use the charger outdoors?

No, the charger is designed for indoor use only (IP20 rating). Protect it from moisture and water to avoid the risk of electric shock.

How long does a typical charge take?

The charging time depends on the battery capacity and selected current. Example: a 12 V / 100 Ah battery charged at 10 A will take about 10 hours. The charger automatically switches to maintenance charge when full.

If the safety instructions are not followed, this may cause damage to the device or serious injury to the user.

For non-maintenance free batteries, please check the acid level and top-up if necessary.

Do not recharge non-rechargeable batteries

The battery terminal not connected to the chassis has to be connected first. The other connection is to be made to the chassis, remote from the battery and fuel line. The battery charger is then to be connected to the supply mains.

After charging, disconnect the battery charger from the supply mains. Then remove the chassis connection and then the battery connection.

This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.

If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.

WARNING

Charging lead acid batteries can generate explosive gases. Please ensure sufficient ventilation and avoid fire or naked flames and smoking. Due to emerging explosive gases it is important to ensure that the battery terminals are connected or disconnected when the charger is disconnected from the mains to avoid sparks.

Battery acid is corrosive. If battery acid gets in your eyes or on your skin, wash immediately with plenty of water and seek urgent medical attention.

Make sure that the battery terminals are contacted with the correct polarity (red to the positive pole terminal, black to the negative pole terminal).

A Spark can arise if the charger is connected to the battery whilst connected to the mains. Please ensure it is disconnected from the mains before connecting or disconnecting the red and black charging leads to or from the battery.

COMMISSIONING

1. Connect charger to the battery with the correct polarity

First connect the charger to the battery to be charged. Connect the red pole terminal to the positive pole (+) of the battery, then the black pole terminal to the negative (-) pole of the battery. Make sure that the battery terminals are connected correctly. If the battery is installed in the vehicle and the battery terminals are not accessible, please consult the vehicle manual for advice.

If the clamps are accidentally attached to the poles the wrong way around, the LED lights red (see fig.1a) and in addition an audible warning signal sounds. Reconnect the terminals with the correct polarity immediately.

2. Connect the device to the mains supply

Insert the mains plug of the charger into the socket. The „POWER“ LED (see fig.1b) will light red.

3. Automatic Voltage Identification/Autosensing

The LEDs 6V/12V/24V (see fig.1C) flash for a few seconds until the device has detected the battery voltage. The corresponding LED lights up permanently. The selected battery will now be charged with the default charging current of 1A. Please check that the detected voltage matches with the voltage of the battery to be charged. If this is not the case, the battery is probably defective. We therefore recommend that the battery should be checked and replaced if necessary.

4. Setting the charge current using the „Mode“ button

Depending on the battery voltage, various charging currents (see fig.2) can be chosen using the MODE button (see fig.1d). If you make no manual adjustment it will charge with the default setting of 1A. We recommend smaller batteries whose capacity is below 20Ah to be charged with 1A. Batteries with more than 20Ah, but less than 40Ah capacity, should be charged with 5A and above 40Ah with 10A.

5. At temperatures below 5 °C (41 °F) we recommend the "COLD TEMPERATURE" mode. To activate, press the „MODE" button for about 3 seconds.

Due to cold temperatures the voltage level of the battery will change, so the battery connected for normal charging process cannot be fully charged to 100%. Therefore, we recommend the „COLD TEMP.“ Mode (see fig.1E), through this, the battery will be fully charged to 100% despite the cold.

1. "REFRESH" will automatically start when the battery is fully exhausted.

If the battery is completely discharged, i.e. the voltage is much lower than the nominal battery voltage such as: below 5V for a 6V battery, below 10V for 12V battery and below 20V for a 24V battery, the charger automatically switches to refresh mode (see fig.1f) and charges the battery by pulse charging until a sufficient voltage for the normal charging process has been reached. The charging current for further charging after the completion of the refresh mode can be further selected.

1. "FAULT" will be displayed when the battery is deemed defective

In the case of a defective battery the „FAULT“ LED (see fig.1g) is on. The charging stops. Unplug the power cord and disconnect the battery. We recommend that you check the battery and replace as required.

1. „BATTERY STATUS“ displays the charge status (see fig.1h)

Using the 3 LEDs (35%, 70%, 100%) you can see the current charge level of the battery:

35% LED flashes battery charge level is between 0% and 35%

35% LED lights, 70% LED flashes battery charge level is between 36% and 70%

35% and 70% LEDs light, 100% LED flashes battery charge level is between 71% and 100%

35%, 70% and 100% LEDs all light battery is fully charged

1. Battery fully charged

Once the battery is fully charged, unplug the mains cord and afterwards remove the battery terminals of the battery, first the black terminal (-) and then the red (+) terminal.

1. Trickle charge

Alternatively, the battery can be left connected for an extended period (e.g. for the winter). The charger detects any loss of capacity and recharges automatically.

1. Automatic start function support

The charger detects during charging that you are trying to start the engine it will automatically supply the highest current available for the selected 6V, 12V or 24V battery. This requires that the charger should be connected to the mains supply and the battery terminals are connected to the battery correctly.
