CTEK 56-677 D250S Dual Automatic Battery Charger

The CTEK D250S charger lets you charge as you drive. This Dual charger has one input for DC sources such as an alternator or starter battery and a second dedicated for solar panels. These two sources will send power to the service battery for charging individually or both can operate together. This allows the D250S to choose between the two sources to optimize battery life while providing fast and highly efficient charging times. When your service battery is fully charged, the D250S can even charge your starter battery automatically. The solar panel input uses an integrated power regulator eliminating the need for an external regulator. It also has a temperature sensor that automatically adjusts the voltage to adapt to hot or cold weather. This means that the voltage will drop in warmer temperatures to prevent overcharging, and raising the voltage in the cold to make sure the battery always has a full charge. Water jet and dust protected and approved for outdoor use (IP65 classified).
