Unlike old battery chargers, CTEK chargers are designed with a focus on simplicity, safety and flexibility.

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.
