CTEK M300 [Power Management CTEK-M300]

M300 is CTEKs powerful charger for boat owners with larger need of quick and effective charging.

Introduction

M300 is temperature compensated, it reconditions a stratified battery with the special RECOND mode, and this is needed after several deep discharges which is common in the marine environment.
The larger CTEK's Marine chargers have 4 meter cables and eyelet terminals for easy installation in the boat. M300 has 5 year warranty delivers 25A and has IP44-classification. All CTEK chargers are spark free, short circuit proof and will not harm the electronic equipment.

THE CTEK UNIQUE 8-STEP CHARGING

  1. DESULPHATlON: Detects sulphated batteries. Pulsing current and voltage removes sulphate from the lead plates of the battery restoring the battery capacity
  2. SOFT START: Tests if the battery can accept charge. This step prevents charging proceeding with a defective battery
  3. BULK: Charging with maximum current until approximately 80% battery capacity
  4. ABSORPTION (battery ready to use): Charging with declining current to maximize up to 100% battery capacity
  5. ANALYSE: Tests if the battery can hold charge. Batteries that cannot hold charge may need to be replaced
  6. RECOND: Choose the RECOND program to add this step to the charging process. The voltage increases during this process to create controlled gassing in the battery. Gassing mixes the battery acid and returns energy to the battery
  7. FLOAT (fully charged): Maintaining the battery voltage at maximum level by providing a constant voltage charge
  8. PULSE, MAINTENANCE CHARGING: Maintaining the battery at 95-100% capacity. The charger monitors the battery voltage and gives a pulse when necessary to keep the battery fully charged

FEATURES AND BENEFITS

Safer for people: CTEK chargers are foolproof to connect, spark proof, reverse polarity protected and there is no need for the battery to be disconnected
Safer for vehicles: CTEK chargers regulate voltage to protect sensitive electronic and audio equipment
CTEK chargers provide: Fully automatic charging, maintenance and battery care. There is no need for specific battery knowledge or charging technology to get the most from a CTEK charger. The patented desulphation function revives drained batteries and extends battery life; float/pulse charging allows ‘set and forget’ for months at a time without harming the battery
CTEK chargers are tough: Shockproof, weatherproof, dustproof, approved for outdoor use (IP44-IP65 depending on model) and in temperatures from -20°C to +50°C
With CTEK quality is guaranteed: all chargers have a warranty of either 2 or 5 years depending on model.
