Even small boats with 12V-batteries (7-75Ah and up to 120 Ah for maintenance charging) require a charger designed to withstand the demanding marine environment. M45 is a high quality 4-step charger with unique functions such as desulphating and safe maintenance charging between seasons.


Featuring different charging programs: one program for small batteries (approx. 7-30Ah) supplying 0.8A, one program for normal size batteries (approx. 40-75Ah) and one program for AGM-batteries, which require slightly higher charging voltage of 14.7V instead of the usual 14.4V, supply 3.6A 


IP65 classification means that M45 is splash and dustproof. It does not generate any harmful galvanic currents, is fully compatible with the boat’s electronics and has been developed to offer safe charging: non-sparking, reverse polarity protection and short circuit proof. M45 comes with a five year guarantee.
