2 Year Warranty

The D250S Dual is a battery charger that gets its energy from DC sources such as alternators, solar panels or wind power and optimizes its power to address the charging requirements of different battery banks. Ctek's D250S Dual automatically selects the connected DC source that currently provides the best energy (of two possible) and thus transforms these energies into high-efficiency multi-stage charging.

Ctek's D250S Dual's charging is done automatically every time you get DC power to the charger, for example from a altenator when the vehicle is started or from the solar panel if and when they are connected.

Ctek's D250S Dual has a temperature sensor that provides optimal charging voltage at all temperatures.  With Ctek's D250S your batteries are always in great condition, charging happens quickly and battery life is extended. Ctek's D250S Dual is a fully automatic 5-speed charger that provides 20A for 12V batteries between 40-300Ah. The charger is approved for use outdoors (IP65 rated - splash, dust proof), protects the vehicle electronics and is suitable for all types of lead acid batteries (Wet, MF, Gel, AGM). It comes with 2 year warranty.

The D250S Dual can be combined with the CTEK SmartPass energy management unit to provide even more advantages to vehicle owners.  For more details on the CTEK SmartPass, click here.

The D250S now comes with an optional Variable Charge Relay, for use with Variable Charge Alternators, found in four wheel drive vehicles manufactured after mid 2011.  See here for information on this option.
