Thanks to numerous features, the ALCT 6-24/2 ensures safe and gentle charging and guarantees optimal performance and a long service life for lead batteries. After successful contact with the pole terminals, the device automatically detects the voltage of the connected lead battery and shows this with the corresponding LED on the display. Depending on the voltage, a charging current can be selected using the MODE button, which means that car batteries can be charged very quickly, but also small motorcycle batteries can be charged very gently. If no setting is made, charging takes place with the preset charging current of 0.5 A. Lead gel, lead fleece and lead acid can be charged. The charger automatically detects when the connected battery is deeply discharged and charges it gently using 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 for winter storage, it detects any loss of capacity and then recharges automatically. Deep discharge is therefore ruled out. This means that batteries can survive the winter well and are always ready for use when needed. At low temperatures below 5 °C, the voltage level of the battery changes, which is why the connected battery cannot be fully charged during normal charging. This can be avoided by selecting the COLD TEMP mode using the MODE button. If the pole terminals are connected the wrong way round, the LED on the display lights up red. A long cable of 2.0 m is particularly practical and enables charging without an extension cable. A special, in-house developed charging process with charging current control and overcharge protection means that the battery automatically switches to trickle charging after it is fully charged. This means that the battery is not overcharged and can remain connected to the charger for a longer period of time. The ALCT 6-24/2 is designed for standby parallel charging
