Lead-acid batteries are maintenance-free, long-lasting and economical energy sources, which are used in many areas. Whether as a backup battery for an uninterrupted power supply in computers and systems, as power source for emergency lighting or as power for golf caddies - lead-acid batteries can be found everywhere. ANSMANN offers with the ALCT 6-24/10 the suitable charger for many applications.The fully automatic charger is suitable for maintenance-free lead-acid batteries (lead-gel, lead-acid, lead-fleece) with 6, 12 or 24 volts. After successful contact with the pole terminals, the device automatically detects the output voltage of the connected lead-acid battery and indicates this via the corresponding LED. If the battery is deeply discharged, an automatic REFRESH mode restores her basic voltage by means of pulsating charging currents, so that the normal charging process can be started. Depending on the voltage, a charging current of 1, 5 or 10 ampere can be selected, whereby car
