CTEK’s D250S Dual offers a unique DIY dual battery system for alternative power and/or solar power that saves time and money.

The CTEK D250S Dual is a 5-step charger that automatically adjusts the charging voltage and current according to the battery’s state of charge and temperature – reducing a battery’s charge time.

A sensor on the CTEK D250S Dual senses the battery temperature and adjusts the required charge by increasing the voltage in cold weather ensuring the battery is fully charged, and dropping the voltage in hot weather to avoid the problems of overcharging.

With the CTEK D250S Dual, vehicle owners can be confident that their battery will always receive the optimal charging voltage, with reduced charge time, while ensuring the battery will be 100 per cent charged.
