Frequently Asked Questions - ALCT 6-24/2 ANSMANN

How to connect the charger to the battery?

Connect the red cable (positive clamp) to the positive terminal (+) of the battery, then the black cable (negative clamp) to the negative terminal (-). Make sure the polarities are correct. Then plug the charger into the mains. To disconnect, first unplug the power cable, then remove the clamps starting with the black (-) then the red (+).

What to do if the red light stays on permanently?

A fixed red light indicates reverse polarity or a connection fault. Check that the clamps are correctly connected (+ to +, - to -). If the problem persists, the battery may be defective or have too low voltage. In this case, try the regeneration mode or replace the battery.

How to set the charging current?

Use the MODE button on the charger. A short press allows you to scroll through the available currents (0.5 A, 1 A, 2 A). The selected current is displayed on the panel. By default, the charger uses 0.5 A.

Which charging current to choose for my battery?

For capacity below 2 Ah, use 0.5 A. Between 2 Ah and 6 Ah, use 1 A. Above 6 Ah, use 2 A. These values are recommended for optimal and safe charging.

How to activate cold temperature mode?

If the ambient temperature is below 5 °C, press and hold the MODE button for about 3 seconds. The COLD TEMP. mode activates and adjusts the charging voltage to ensure a full charge despite the cold.

What is regeneration mode?

Regeneration mode (REFRESH) is a pulsed charging mode that activates automatically when the battery is very discharged (voltage below 5 V for 6 V, 10 V for 12 V, 20 V for 24 V). It allows recovery of deeply discharged batteries. Once the voltage is sufficient, normal charging resumes.

What does the 'FAULT' display mean?

The 'FAULT' display indicates that the battery is considered defective by the charger. Charging stops immediately. Disconnect the charger and battery. Check the battery condition and replace it if necessary.

Can I leave the charger plugged in permanently?

Yes, the charger has a maintenance charge function. Once the battery is full, it automatically maintains the charge by compensating for losses. This is useful for winter storage. However, it is recommended to unplug the charger when not in use.

How to clean the charger?

Always unplug the charger before cleaning. Use a dry, lint-free cloth to wipe the casing. Never use solvents, liquids, or abrasive products.

What are the essential safety precautions?

Use the charger only indoors, in a dry and well-ventilated area. Do not cover the device. Avoid any flame or spark near the battery as explosive gases may be released. Never charge a frozen or damaged battery. Keep out of reach of children.

SAFETY INSTRUCTIONS

Keep your charger in a dry place (indoor use only). There must be adequate ventilation - a window partly open for example.
Do not use the device if there are signs of any damage to the housing, mains plug or cables. Please contact an authorized dealer!
The charger should not be covered during use.
Use the device only as intended (according to the charger specifications and instructions).
In order to avoid the risk of fire and / or electrical shock, the charger must be protected against high humidity and water.
Do not use this charger near flammable gases or liquids at any time.
Never attempt to open the charger.
Never charge a frozen or damaged battery.
When the charger is not in use - disconnect it from the mains supply.
Improper use of the battery charger may result in danger to the user.
Keep away from children! Children should be supervised to ensure that they do not play with the charger.
This device is not to be used by children or persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they are given adequate supervision and specific instructions!
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.

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.

CARE & MAINTENANCE

Carry out repairs only through authorized dealers.
Carry out cleaning and maintenance work to be done only when the mains plug is disconnected.
Cleaning only with a dry cloth.

OVERVIEW FUNCTIONS

Adjustable charging current (0,5A/1A/2A) dependent on battery nominal voltage.
Overcharge protection.
Protection against short-circuit and wrong polarity.
Automatic start of recharge.
Automatic „REFRESH“ mode.
Selectable „COLD TEMP.“ mode.

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). 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 0,5A. We recommend smaller batteries whose capacity is below 2Ah to be charged with 0,5A. Batteries with more than 2Ah, but less than 6Ah capacity, should be charged with 1A and above 6Ah with 2A.

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.

6. „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.

7. "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.

8. 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.

9. 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.
