CTEK M300: Great Choice for the Marine Market and Boats!

CTEK M300

CTEK M300 is an 8 step, fully automatic primary switch mode battery charger. It is a great choice for the marine market and boats with batteries from 50-500Ah and maintenance of the starter battery with the CTEK M300 STARTER. Unlike old battery chargers, CTEK chargers are designed with a focus on simplicity, safety and flexibility. They will recover the batteries quickly and satisfy the needs and comfort of the boat owner.

Fully automatic
In addition to normal charging, CTEK M300 offers a fully automatic charging cycle with its patented system for pulse maintenance. CTEK M300 analyses the condition of the battery, charges when necessary and maintains the battery when the boat is not in use. CTEK M300 STARTER offers fully automatic pulse maintenance charging for the starter battery.

No harmful galvanic currents
Neither the CTEK M300 nor CTEK M300 STARTER produces any harmful galvanic currents that causes corrosion which quickly damages various metal components under the boat, including propellers and ladders.

Counteracts sulphation
Unused batteries lose their power and their life is shortened through sulfation. It is also more difficult to charge sulfated batteries. The CTEK M300 has a patented method for reconditioning sulfated batteries. The charger analyzes the state of the battery and, if possible, recovers the battery and its power.

Recondition the battery
Using CTEK’s unique RECOND mode can correct the acid stratification that often occurs in fully discharged batteries. The battery thereby has it is power restored and enjoys an extended service life.

Designed for safety
CTEK develops all of its battery chargers with safety in mind, for the user, for the battery and for the sensitive electronic equipment installed in all modern boats. CTEK M300 and CTEK M300 STARTER are non-sparking, reverse polarity protected as well as short-circuit-proof and they do no damage to the boat’s electronic equipment either.

Designed for a tough marine environment
CTEK M300 is IP44 classed which means that it is approved for outdoor use. They charge equally well at –20°C as they do at +50°C thanks to the charging voltage being adapted to suit the temperature of the battery, and that the components and cables are of the highest possible quality. CTEK M300 STARTER is IP65 classed and also charges in the same temperature conditions as the CTEK M300.

Silent night mode
With CTEK M300 there is no need to switch off the charger in order to sleep soundly. The practical and convenient NIGHT mode function now provides silent charging.

Complete purchase guaranteed
When buying a CTEK M300 there is a guaranteed complete purchase which means there is no need to buy any additional components or accessories.
