CTEK D250SE, 20A, 12V Battery Charger For Starter And Service Batteries In RV, Truck And Overlanding Vehicles, Solar Battery Maintainer, 12V Lithium Ion Battery Charger And Smart Alternator Compatible

• Battery Support On the Go: 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 12V lithium batteries (*12V LiFePO4).
• Achieve Nominal Power from Your Solar Output: Solar Panel Regulator with Maximum Power Point Tracking (MPPT) optimizes available power.
• Charge Service and Starter Batteries: When the service battery is fully charged, the D250SE will automatically redirect maintenance charge power to the starter battery.
• Smart Alternator Compatible: Full functionality with all types of alternators.
• Built-In Temperature Sensor: Allows you to achieve maximum charge levels no matter what the temperature.
• Safe and Easy to Use: Splash and dustproof, designed to protect vehicle electronics and non-sparking, reverse polarity protected, and short-circuit proof. Clean voltage and current delivery ensures no surges or spikes.
• Protects Sensitive Equipment: Unlike less-sophisticated chargers, there is no need to disconnect the battery; the D250SE is specially designed to not damage electronic systems. No overcharge or undercharge ever.
• 2-year warranty.

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. 12 V: WET, MF, Ca/Ca, AGM, EFB, GEL, LiFePO4, *) 12V lithium batteries (LiFePO4, Li-Fe, Li-iron, LFP)
