CTEK D250SE DC to DC Battery Charger - 12V, 20A

The CTEK D250SE – 12V 20A DC DC Battery Charger 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 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. *12V lithium batteries (LiFePO4, Li-Fe, Li-iron, LFP)
