AEG Automotive 10618 Microprocessor Charger Car Battery LD8.0 In addition to the familiar features, the HF-MCU (High Frequency Micro Control Unit) chip is used for the first time in AEG chargers. This chip makes it possible to charge a car battery with 7 charging stages 20% faster and more gently than comparable competitor products with 9, 10, 11 and other charging stages. Another feature of the devices is the auto-start function, which allows the charger to start automatically when the mains voltage is restored and continue the charging process in the event of a power failure. This ensures continuous charge retention for months. After selecting the connected battery type (6V /12V or 24V LD 8.0), the charger recognises the battery capacity and the battery condition and uses this to calculate the required charging parameters (charging voltage, charging current). This enables efficient and safe charging. If an incorrect battery voltage is set or the battery is faulty, charging will not take place and the Error LED (9) will light up. The AEG microprocessor charger is designed for charging open and a variety of closed batteries, such as those installed in cars, ships, lorries and other vehicles.
