Dual battery charger - CTEK D250

The D250SE charger is a 20A dual-input charger with selectable charging voltage.

It is a fully automatic 5-stage charger that delivers 20A of power to any 40-300Ah 12V lead-acid or lithium service battery. It has selectable charging algorithms for AGM and lithium batteries and can use energy through its dual input from the solar panel alternator. When the service battery is fully charged, the D250SE automatically transfers the maintenance charge to the starter battery.

The D250SE maintains a stable power supply of up to 20A for vehicles equipped with intelligent ECU-controlled alternators (often known as "smart" alternators). It also has a temperature sensor to ensure optimized charging in all weather conditions.
