Description

APTO™ technology automatically detects the battery type and activates the appropriate charging program, which displays the remaining charging time until the battery is ready for use. No buttons, no modes – simply connect the CS ONE to any 12V battery and charge. The polarity-free clamps eliminate the guesswork of which clamp goes where. No more incorrect connections. The clamps are also spark-protected, so if they accidentally touch, nothing will happen. Additional functions can be unlocked using the CTEK app with Bluetooth®. Select RECOND to restore and recondition the battery. Select WAKE UP for lithium-ion batteries with low-voltage protection, or to revive deeply discharged lead-acid batteries. Select SUPPLY to transform the CS ONE into a convenient 12V power source. The voltage and current supplied by the charger can also be monitored.

CS ONE: Charging batteries just got even easier.
The new CTEK CS ONE – a world first for car battery care and maintenance with APTO™, the adaptive charging technology. Equipped with APTO™ technology, the CS ONE is CTEK’s most innovative battery charger to date: you don’t have to worry about which clamp goes where!

The CS ONE stands for thoughtful simplicity and enables innovative polarity-free charging. Simply connect the CS ONE to any 12V battery and enjoy consistently optimal charging performance. Thanks to the reverse-polarity protected clamps, you no longer have to worry about which clamp goes where, so you’ll never make a wrong connection again.

Stress-free, safe battery charging and conditioning. Your daily companion for a healthy and ready-to-go battery.
The CTEK CS ONE uses adaptive charging technology, also known as APTO™, which detects the battery type, size, and required charging method. The battery is then automatically charged with a charging program specifically tailored to its needs. As an additional feature, the charger also displays the remaining charging time and when the battery is ready to start the vehicle. The integrated temperature sensor automatically adjusts the charging voltage for fast and safe charging in both cold and hot conditions.

The CS ONE is equipped with polarity-free and spark-free clamps for safe and easy charging of the vehicle battery. Clearly visible countdown LEDs indicate the remaining time until the battery is fully charged and when it is ready to start the vehicle.

The CS ONE stands out with its uncomplicated operation: you no longer need to select buttons or modes. All charging progress information can be read quickly and conveniently on the LED display. Additional device functions can be unlocked with the free CTEK app. These include the “RECOND” function, which allows you to recondition your battery. The “WAKE UP” function helps you revive lithium batteries with undervoltage protection or deeply discharged lead-acid batteries. The “SUPPLY” function transforms your CS ONE into a useful 12V power supply. With the CTEK app, you have complete control over the care and maintenance of your vehicle battery using your smartphone.

The world’s smartest and fully adaptive charger,
the CTEK CS ONE cares for batteries with a unique new approach. We launched the first intelligent charger on the market. With our advanced APTO™ technology, we are the first to introduce a fully adaptive charger. The CS ONE goes beyond conventional multi-stage charging – it completely takes over the work of maintaining and servicing your vehicle battery.
