CTEK D250SE, 20A, 12V Battery Charger For RV, Truck And Overlanding Vehicles

The D250SE is a fully automatic, 5-step charger that provides up to 20A of power to any 12V lead-acid or lithium service battery from 40–300Ah. It features selectable charge algorithms for AGM and lithium batteries and can utilize 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 charger can maintain a stable output up to 20A to vehicles fitted with smart ECU-controlled alternators and also has a temperature sensor for optimized charging, regardless of weather conditions.

Achieve Nominal Power from Your Solar Output: The D250SE's solar panel regulator with Maximum Power Point Tracking (MPPT) optimizes the available power, ensuring you can get the most from your solar setup.

Charge Service and Starter Batteries: The charger's ability to automatically redirect maintenance charge power to the starter battery when the service battery is fully charged is a convenient feature, keeping both batteries in optimal condition.

Smart Alternator Compatible: The D250SE is designed to work seamlessly with all types of alternators, providing full functionality and ensuring your charging system operates at peak efficiency.

Built-In Temperature Sensor: The integrated temperature sensor allows the charger to achieve maximum charge levels no matter the ambient temperature, enhancing the overall performance and longevity of your batteries.

Safe and Easy to Use: The D250SE is splash and dustproof, designed to protect vehicle electronics and featuring non-sparking, reverse polarity protection, and short-circuit proof design. Its clean voltage and current delivery ensure no surges or spikes, making it a safe and reliable choice.

Protects Sensitive Equipment: Unlike less-sophisticated chargers, the D250SE is specially designed not to damage electronic systems, eliminating the need to disconnect the battery. You can enjoy worry-free charging without the risk of overcharge or undercharge.

Backed by a 2-year warranty, the D250SE is a versatile and reliable charging solution that can handle a wide range of 12V lead-acid and lithium* batteries, making it an excellent choice for a variety of applications.
