M300 is the charger we recommend for boats with both start and service batteries. Accompanying M300 is the maintenance charger M300starter which solely takes care of the start battery. The 25A-charger can then give maximum charging to the service batteries. The charger has a four metre long secondary cable and a temperature sensor for optimised charging irrespective of temperature, which gives extra flexibility in permanent installations. M300 is a fully automatic 8-step charger that supplies 25A and is ideal for batteries between 40-500Ah. M300 analyses whether the battery can accept and retain the charge, it removes harmful lead sulphate crystals, gives an effective charge and automatically switches to safe maintenance charging when the battery is fully charged.
The practical Recond mode reconditions the battery following deep discharge cycles, which can occur after a long day at sea. If you intend to stay overnight onboard you can switch to Night mode for silent charging.
IP44 classification means M300 is approved for outdoor use. It does not generate any harmful galvanic currents, is fully protected from producing voltages that can damage the vehicle’s electronics and has been developed to offer safe charging: non-sparking, reverse polarity protection and short circuit proof. M300 comes with a five year guarantee.
