CTEK CS ONE Battery Charger and Maintenance Device with APTO Technology (Adaptive Charging), Fully Compatible with Cars, Motorcycles, Leisure Vehicles, Vans and Boats

APTO™ Technology automatically recognises the type of battery you’re using, and then automatically delivers a customised charging program, telling you how long until the battery is charged and ready to go. No buttons to press or modes to select – just connect the CS ONE to any 12V battery and simply charge. Polarity free clamps mean you don’t even need to worry about which clamp goes where, so you’ll never make a wrong connection again. The clamps are spark free too, so don’t worry if you accidentally touch them together. Unlock additional features using the Bluetooth® enabled CTEK App. Select ‘RECOND’ to restore and recondition your battery. Choose ‘WAKE UP’ for lithium batteries with under voltage protection or to bring deeply discharged lead-acid batteries back to life. Select ‘SUPPLY’ to turn the CS ONE into a useful 12 V supply. You can also monitor the voltage and amps being delivered by the charger.


  • RECOND option to restore and recondition lead-acid batteries.
  • WAKE UP option to revive seemingly dead lithium and lead-acid batteries.
  • 12V SUPPLY to support the battery during service work and retain contact power to the vehicle during battery replacement / removal.
  • ADVANCED SETTINGS to monitor charger voltage & amperage.
  • Can be left safely connected for long periods during maintenance charging.
  • New durable design to make it easy to handle, with unique mounting system on the back for quick connection to CS accessories.
  • 5 year warranty.
