  • Voltage

    12

    Suitable for passenger cars, motorcycles, and small trucks.

  • Compatible Batteries

    AGM

    Suitable for use with sealed AGM (Absorbent Glass Mat) batteries. Commonly used in modern vehicles and start-stop systems.

    GEL

    Suitable for use in sealed batteries with electrolyte in GEL form. Often used in motorcycles and passenger vehicles.

    Lead Acid

    Suitable for use in classic types of batteries with liquid electrolyte. Widely used in cars and motorcycles.

  • Maximum Charging Current

    Measured in Amperes (A), it determines how quickly the device can "fill" your battery. The higher the number, the faster the charging. For small batteries (e.g. motorcycle) or simple maintenance, a few Amperes are enough, while for faster charging in cars you will need a higher current.

Description

Description

The CTEK MXS 3.8 is an extremely reliable, fully automatic smart charger and battery maintainer of the "plug-and-play" type from Swedish company CTEK. 

Designed for the care of 12V batteries in motorcycles, cars, boats, and jet skis, it offers professional maintenance and protection without requiring technical knowledge from the user.

(Note: The UK version has a British power plug and for use in Greek sockets, a simple plug adapter is needed).

7-Stage Automatic Program: The built-in microprocessor controls 100% of the charging process. It starts with automatic desulfation, proceeds to quick full charging, and ends with smart pulse maintenance.

Winter / AGM Mode (Snowflake Mode 14.7V): A special program that increases the charging voltage to 14.7V. It ensures the most complete and fastest possible charging under extreme cold conditions, and is ideal for properly charging demanding AGM technology batteries (e.g., in vehicles with Start/Stop systems).

Battery Diagnostic Test: At startup, the charger performs an automatic check to determine if the battery can accept and hold the charge, alerting the user promptly in case of internal failure.

Safe "Connect & Forget" 24/7 Maintenance: Designed to stay permanently connected to the battery for months (e.g., during winter storage of motorcycle or boat). It maintains the voltage at 100% through pulses, extending the battery's lifespan without the risk of overcharging.

Absolute Safety: 100% safe for sensitive electronic systems and vehicle control units. It features full protection against sparks, reverse polarity (incorrect connection), and short circuits.

Technical Specifications

  • Maximum Charging Current: 3.8 Amperes (automatically adjusts according to the selected program).
  • Battery Compatibility: 12V Lead-Acid batteries of all types: WET (liquid electrolyte), MF (maintenance-free), Ca/Ca (calcium), AGM, and GEL. (Not compatible with Lithium batteries).
  • Capacity Range: Ideal for charging batteries from 1.2 to 85 Ah (and for simple maintenance of larger batteries up to 130 Ah).
  • Minimum Starting Voltage: Can recognize and start charging if the battery has at least 2.0V.
  • Waterproof & Protection: IP65 certification (dust, moisture, and water spray resistant), suitable for outdoor use.
