This automatic car charger with nine charging steps has 28 selectable charging programs. This microprocessor-controlled battery charger has the great advantage of charging all common car battery sizes. For lawn mowers, motorcycles, cars, trucks, motorcycles, This charger can be used for mobile homes, agricultural machinery or, for example, tractors We recommend battery capacities from 10Ah to 500Ah for the rapid charging. For pure maintenance charging you can also use vehicle batteries with a capacity of up to 850Ah. 28 charging programs are available for you. Thanks to the program variety, you can choose the right voltage (V) and the optimal charging current (A) for every battery size and 12V/24V lead acid battery type. Everything you need for this battery charger is done automatically, right up to the trickle charge. The enclosed eyelet cable can be permanently mounted to the vehicle battery for charging. This Dino KRAFTPAKET car charger has a maximum 9-phase automatic charging program, which is only suitable for charging and maintenance charging of 12V or 24V lead-acid car batteries (EFB/AGM/GEL/CAL/lead-acid). Even old deep-discharged batteries are recognized and 'relived' with the refresh function. The basic requirement is a battery without a defect with a minimum voltage of 0.5 Volt.Suitable for trickle charge:If desired, the charger can remain connected to the battery in the long run. The in-built electronics with the program-controlled processor prevents an overcharging and receives the charge level. The device has an intelligent diagnostic function for the connected battery, for this the voltage drop is measured without load for a certain period of time. A new charging cycle is automatically started in case of a voltage drop in the trickle charge. For continuous charging, the eyelet cables are permanently mounted at the vehicle battery to be charged. The car battery charger is connected to the eyelet cable via a quick connection plug. This is very practical, as the eyelet cables can remain permanently connected to the battery. The device has a robust design with an internal fan so that it can be permanently integrated into the vehicle electrical system. The charger has long holes on the housing for permanent installation in the vehicle or garage. More effective with switched-mode power supply technology + microprocessor.Rapid charging:The processor-controlled charge controller with switched-mode power supply technology enables the maximum quick charge current from 25 Ampere at 12V to 80% charging. Therefore, the charging is much shorter than with a conventional charger with a 25 ampere rated current, which shows a dropping charging current due to the design (a maximum of 12A is available at 24V). The charger is carried out robustly with an internal fan. It is able to run under full load for a long time due to the internal fan control. The blower only switches on when heated inside from 40°C. Only from the inner temperature of 50°C is the charging current reduced. If the charging current is reduced, the charging time is extended. Closed, splash-proof chargers, for example, have no blower control and are therefore not able to deliver the highest possible charging current over a long period of time, because the internal temperature is heated due to lack of cooling air and the charging current is quickly reduced. This charger is designed for quick and gentle charging with high charging currents and is therefore only suitable for indoor use.Identifies defective batteries:The car charger has an intelligent diagnostics function to determine whether the battery is faulty. For this purpose, the voltage drop without charging current is measured on the connected car battery for a certain period of time. NOTE: If the vehicle battery is in poor condition, the battery charger can gently go through the pre-selected charging program up to three times. This can last up to 48 hours.Revitalization with refresh function:The refresh function allows 100% charging with a reduced charge current up to the gas range. The resulting flow in the electrolyte ensures a mixing and eliminates a concentration gradient of the acid. A beginning sulphation or hardening of the plates is converted back. The automatic charging program runs through different programming steps and can repeat these up to three times, in order to regenerate a battery that is badly maintained or that is too long. There is thus the possibility (this unfortunately not in all cases) of using the battery still further without a costly new purchase. This however leads to a longer charging time.Prevents discharging:In the case of maintenance charging, the battery is recharged at voltage drop. Thus, a harmful sulphation is targeted h. A decrease in capacity and a deterioration of high-current behavior. The connected battery does not discharge. Memory:Charges automatically even after power failures. After interruption of the mains power supply, the device starts af
