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 batteries can be charged very quickly, but also small motorcycle batteries can be charged very gently. If no setting is made, charging is done with the preset charging current of 1 ampere. At low temperatures below 5°C, A COLD TEMPERATURE mode (optional) ensures that the lead-acid battery is fully charged despite the cold. A clear LED-display informs safely and reliably about the made settings as well as about the charging progress (35-70-100%). Thanks to a special charging process developed in-house, the automatic switchover to maintenance charging takes place after the complete charging. This means that the battery is not overloaded and can remain connected to the charger for a longer period of time. Batteries of motorcycle, motor boat, lawn mower etc. are so good over the winter and are ready to use whenever required.Designed for standby parallel operation, the ALCT 6-24/10 can remain connected to the battery continuously and keeps it fully charged, even if the battery is charged/discharged at the same time. This means that the rechargeable battery is always available at full capacity. And if he doesn't, the ALCT 6-24/10 can even provide jump-start assistance.For optimum operating safety, the lead-acid charger is equipped with electronic protection against short-circuit and polarity reversal. Thanks to its numerous features, the ALCT 6-24/10 provides for a safe and gentle charging and guarantees an optimum performance and long life of lead-acid batteries. TestPraktiker rated car & lead battery charger ALCT 6-24/10 with very goodThe consumer magazine TestPraktiker tests and reports on products in real daily use, i.e. directly in practice and not under laboratory conditions. Is tested under with the help of specialist journalists and engineers, by consumers for consumers.
