CTEK M300

The M300 is recommended for boat owners who need quick and effective charging for larger service batteries. The 12V, 25A M300 is the ideal choice for recovery charging and maintaining all types of marine batteries from 40Ah up to 500Ah. It has a range of functions, including a Recond mode for reconditioning deeply discharged batteries, and a temperature sensor which optimises the charge if the temperature deviates from +25ºC. It also has a special Silent Night mode which reduces the noise of the fan by lowering the output power during periods of low energy consumption, such as at night. The M300 comes with a long 4m cable with eyelets for easy installation on your boat.
