Ansmann ALCT 6-24/4 1001-0017 Automatic charger 6 V, 12 V, 24 V 1 A, 2 A, 4 A

Intelligent and safe charging control even under frosty conditions!

Through numerous features the ALCT 6-24/4 provides for a safe and gentle charging and guarantees an optimum performance and long life of lead-acid batteries. After successful contact with the pole terminals, the device automatically detects the voltage of the connected lead battery and indicates this via the corresponding LED on the display. Depending on the voltage, a charging current can be selected via the "MODE" button, whereby car batteries can be charged very quickly but also small motorcycle batteries can be charged very gently.

For 6 V/12 V or 24 V lead-acid batteries with a capacity of 4.5Ah - 160Ah and up to 4A charging current

The charging currents are as follows: 1a at 6V, 12V, 24V/2A at 12V, 24V/4A at 12V. If no setting is made, charging is done with the preset charging current of 1A. Lead-gel, lead-fleece and lead-acid in the voltage 6V, 12V, 24V are loadable.

Refresh mode - total discharge of the battery excluded and gentle over winter

The charger automatically detects when the connected battery is deeply discharged and gently charges it by pulsating charging currents for 20 minutes until a sufficient basic voltage is reached for the normal charging process.

If the battery is permanently connected to the charger during the winter, it detects a possible loss of capacity and then charges automatically. This prevents deep discharge. Batteries of motorcycle, motor boat, lawn mower etc. are so good over the winter and are ready to use whenever required.

Cold-Temp mode

At low temperatures below 5°C, the voltage level of the battery changes and the connected battery cannot be fully charged during normal charging. This can be avoided by selecting the "COLD TEMP" mode via the "MODE" button.

Reverse polarity protection, overload protection, practical long cable

If the terminal clamps are swapped, an acoustic warning signal sounds and the LED on the display lights up red. A long cable of 2.0m is particularly convenient and allows charges without extension cables.

A special charging process, developed in-house, with charge current control and overload protection, automatically switches over to maintenance charging after full charging. This means that the battery is not overloaded and can remain connected to the charger for a longer period of time.

The ALCT 6-24/4 is suitable for standby parallel operation, i.e. it can remain permanently connected to the battery and always keeps it full, even if the battery is simultaneously charged/discharged.



The ALCT 6-24/4 lead-acid charger has been awarded the top rating 1.3 by the magazine "do-it-yourselfers"

In the first edition 2015 of the test magazine "DIY Practice", ANSMANN's new ALCT 6-24/4 lead charger has been added

Very good with the overall grade 1.3.

Tested under both normal and extreme conditions. After freezing nights, the lead-acid charger was used to breathe life into a battery - with success. Similarly, a motorcycle battery that had already weakened the year before was revived. The test person was also completely enthusiastic about the equipment. Especially the high-quality and stable pole terminals received very positive support.

The conclusion was accordingly very good:

The self-contained battery detection also allows a layman to operate the device with ease. The ALCT 6-24/4 does everything by itself - "this is how battery care goes today".
