CTEK D250SE 12V 20A DC/DC Battery Charger

Description

CTEK D250SE 12V 20A DC/DC Battery Charger

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. *) 12V lithium batteries (LiFePO4, Li-Fe, Li-iron, LFP)
