    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 CS One redefines battery charging through absolute simplicity and artificial intelligence. Thanks to the patented APTO™ (Adaptive Charging) technology, the charger does all the thinking for you. 

It automatically recognizes the type, size, and health status of the battery and creates a 100% personalized charging program, while also showing you a countdown of how many hours remain until the battery is fully charged.

Main Features & Revolutionary Functions

Polarity-Free Clamps: This is a global innovation. Both clamps are black, as it doesn't matter which one you connect to the positive (+) and which to the negative (-) terminal. The charger automatically detects the polarity and safely delivers the current.

Fully Automated Multi-Chemistry Function: It is fully compatible with all lead-acid battery types as well as modern Lithium batteries (LiFePO4). You don't need to press any battery type selection button; the device reads it automatically.

Wi-Fi & Bluetooth Connection via CTEK App

The device connects to your smartphone via the free app. From the app, you can unlock specialized professional functions:

  • RECOND (Revitalization): A special program for restoring and reconditioning deeply discharged or sulfated lead-acid batteries.
  • WAKE UP (Awakening): Sends pulses to "wake up" lithium batteries whose protection system (BMS) has been locked or completely dead lead batteries.
  • SUPPLY (Constant Power): Converts the charger into a stable power supply of 13.6V (up to 8A) for diagnostic checks or to prevent the vehicle's memory from being lost during battery replacement.
  • Smart Countdown Indicator: The LED display on the charger accurately shows how many hours remain (e.g., 4, 2, 1 hour) until the battery is fully charged.
  • Safe 24/7 Maintenance: Once charging is complete, it automatically switches to safe pulsed maintenance. It can stay connected for months without supervision.

Technical Specifications

  • Maximum Charging Current: 8.0 Amperes (Very powerful, ideal for fast charging).
  • Battery Compatibility: 12V of all types: WET, MF, Ca/Ca, AGM, EFB, GEL, as well as LiFePO₄ (Lithium).
  • Capacity Range: Supports batteries from 3 to 180 Ah (suitable for motorcycles, cars, SUVs, boats, and commercial vehicles).
  • Minimum Starting Voltage: Can recognize and start charging from 1.5V.
  • Protection & Waterproofing: IP65 certification (dust and water splash resistant). Features 100% protection against sparks, short circuits, and overheating.
