This automatic car charger with nine charging steps has 28 selectable charging programs. With this microprocessor-controlled battery charger, you have the great advantage of being able to charge all common car battery sizes. It can be used for lawnmowers, motorcycles, cars, trucks, motorhomes, agricultural machinery, or tractors. We recommend battery capacities from 10 Ah to 500 Ah for a quick charge. For pure maintenance charging, you can also use vehicle batteries with capacities up to 850 Ah. You have 28 charging programs available for this purpose. Thanks to the variety of programs, the appropriate voltage (V) and optimal charging current (A) can be set for each battery size and every 12V/24V lead-acid battery type. Everything else is handled automatically by this battery charger, including maintenance charging. For the charging processes, the included ring terminal cable can also be permanently mounted to the vehicle battery. This Dino KRAFTPAKET car charger features a maximum 9-stage automatic charging program that is exclusively suitable for charging and maintaining 12V or 24V lead-acid car batteries (EFB/AGM/GEL/CAL/Lead-Acid). Even old deeply discharged batteries are recognized and "revived" with the refresh function. A prerequisite is a battery without defects and with a minimum voltage of 0.5 volts. The charger can remain permanently connected to the battery if desired. The built-in electronics with the program-controlled processor prevents overcharging and maintains the charge level. The device has an intelligent diagnostic function for the connected battery, measuring the voltage drop without load over a certain period. During maintenance charging, a new charging cycle is automatically started when a voltage drop occurs. For continuous charging, the ring terminal cables are permanently mounted to the battery being charged.
