The devices are characterized by high operational reliability. High-quality charging technology combined with intelligent microprocessor control ensures precise adherence to charging voltages, currents, and times. The main charging output with IU1oU2 charging characteristic can be optimally adjusted for acid\/wet batteries, gel, or AGM\/fleece batteries.\u003cbr\u003e With the temperature sensor (recommended accessory) for battery temperature compensation, the charging voltage is automatically increased at low temperatures (winter operation), allowing the weakened battery to be charged better and faster. At summer temperatures, the charging voltage is reduced, thereby reducing the stress (gassing) on the battery and increasing the lifespan of sealed (e.g., gel) batteries. The second charging output has reduced voltage and current and is used for supportive charging and trickle charging of the vehicle's starter battery during long periods of inactivity.\u003c\/p\u003e \u003cp\u003e\u003cbr\u003e \u003cstrong\u003eNote\u003c\/strong\u003e: The classic functionality of PWM controllers is becoming less compatible with the sensitive battery management systems of modern LiFePO4 batteries.
