The ideal choice for larger batteries

Compact, tough and powerful. 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 +25C. 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.
