CTEK D250SE, 20A, 12V Battery Charger for RV, Truck and Overlanding Vehicles

The D250SE is a fully automatic, 5-step charger that supplies up to 20A of power to any 12V lead-acid or lithium service battery from 40–300Ah. It has selectable charge algorithms for AGM and lithium batteries and can use power through its dual input from alternator, solar panel, and wind power. When the service battery is fully charged, the D250SE will automatically redirect maintenance charge power to the starter battery. The D250SE can maintain a stable output up to 20A to vehicles fitted with smart ECU-controlled alternators and also has a temperature sensor for optimised charging, regardless of weather conditions.

The D250SE is a versatile and reliable battery charger that can be used to power a variety of 12V lead-acid and lithium* batteries. It is equipped with selectable charge algorithms that can be tailored to the specific battery type, ensuring optimal charging performance. The charger can draw power from multiple sources, including alternators, solar panels, and wind power, making it a flexible and convenient solution for on-the-go charging.

One of the key features of the D250SE is its ability to automatically redirect maintenance charge power to the starter battery once the service battery is fully charged. This ensures that both the service and starter batteries are kept in top condition, reducing the risk of unexpected battery failures and ensuring reliable performance.

The D250SE is also designed to be compatible with smart ECU-controlled alternators, allowing it to maintain a stable output of up to 20A regardless of the alternator's output. This feature is particularly useful for vehicles with sophisticated electrical systems, where maintaining a consistent voltage is critical for the proper functioning of electronic components.

Another important aspect of the D250SE is its built-in temperature sensor, which allows it to optimize the charging process based on the ambient temperature. This ensures that the battery is charged at the most appropriate rate, regardless of the weather conditions, maximizing the battery's lifespan and performance.

In terms of safety and ease of use, the D250SE is designed with the user in mind. It is splash and dustproof, and it is non-sparking, reverse polarity protected, and short-circuit proof. Additionally, it delivers clean voltage and current, ensuring that no surges or spikes occur, which could potentially damage sensitive electronic equipment.

Unlike less-sophisticated chargers, the D250SE is specially designed to not damage electronic systems. There is no need to disconnect the battery, as the charger is capable of safely charging the battery without causing any harm to the vehicle's electronics. This feature provides peace of mind and convenience for the user, as they can charge the battery without worrying about potential damage to their vehicle.

The D250SE comes with a 2-year warranty, ensuring that users can rely on the product's quality and performance for an extended period. Overall, the D250SE is a highly capable and versatile battery charger that offers a range of features and benefits for users who require reliable and efficient on-the-go charging solutions.
