CTEK D250SE Smart Alternator

The CTEK D250SE Smart Alternator with dual input 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 CTEK D250SE Smart Alternator 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.

With award winning Swedish technology, the Dual Input D250SE allows you to enjoy your vehicle more with maximized battery capacity as the ideal charger for vehicles without access to a mains power supply.
