Even smaller boats with 12V-batteries need a charger designed to withstand the demands of a marine environment. The CTek M45 is a high quality 4-step charger with unique functions such as desulphating and safe maintenance charging between seasons.

The CTek M45 features several different charging programs: a program for small batteries (approx. 7-30Ah) supplying 0.8A, a program for more normal size batteries (approx. 40-75Ah) and a program for AGM-batteries, which need a slightly higher charging voltage of 14.7V instead of the usual 14.4V, supply 3.6A

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