APTO⢠technology automatically detects the battery type and then activates the appropriate charging program, which shows the remaining charging time until ready for use. No buttons, no modes â simply connect the CS ONE to any 12 V battery and charge it. The polarity-free terminals save you the trouble of thinking about which terminal to connect where. No more incorrect connection. The terminals are also spark-proof. If they touch each other accidentally, nothing happens. Other functions can be activated via 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 bring fully discharged lead-acid batteries back to life. SELECT SUPPLY to turn CS ONE into a convenient 12V source. The voltage and current supplied by the charger can also be monitored.CS ONE: Charging batteries is now much easierThe new CTEK CS ONE â the world's first for the maintenance and maintenance of vehicle batteries with APTOTM, the technology for adaptive charging. The CS One equipped with APTOTM technology is the most innovative battery charger from CTEK so far: You do not have to worry about which clamp comes where!The CS ONE stands for thought-out simplicity and enables innovative polarity-free charging. Simply connect the CS ONE to any 12 V battery and enjoy a constantly optimally tuned charging power. With reverse polarity protected terminals, you no longer have to worry about which terminal belongs to where, so that you never make a wrong connection again. Stress-free, safe charging and conditioning of batteries. Your daily companion for a healthy and ready-to-use batteryThe CTEK CS ONE uses the adaptive charging technology, also called APTOTM, which detects the battery type, size and the required charging type. The battery is then automatically charged with a charging program specially designed for the need. As a further feature, the charger also shows the remaining charging time and the first readiness for start-up. The integrated temperature sensor automatically adjusts the charging voltage for fast and safe charging in cold and heat.The CS ONE has been equipped with polarity and spark-free terminals for safe and easy charging of the vehicle battery. Well-recognizable countdown LEDs indicate the remaining time until the battery is fully charged and the battery is ready to start for the first time.The CS ONE scores with its simple operation: You do not need to select any buttons or modes any more. All information on the charging progress can be read quickly and conveniently on the LED display. Additional device functions can be activated with the free CTEK app. These include the RECOND function, with which you can recondition your battery. THE WAKE UP function helps you to bring lithium batteries with low voltage protection or deeply discharged lead-acid batteries back to life. THE SUPPLY function is used to convert your CS ONE into a useful 12 V supply. With the help of the CTEK-App you have complete control over the maintenance and maintenance of your vehicle battery with your Smartphone.The world's most intelligent and fully adaptive chargerCTEK CS ONE maintains batteries with a unique new approach. We have launched the first intelligent charger on the market. With our advanced APTOTM technology, we are the first to introduce a fully-adaptive charger. The CS ONE goes beyond the conventional multi-stage charging â it takes the work out of maintaining and maintaining your vehicle battery completely. And thanks to the polarity-free terminals, the CS One is as safe as easy to use.A charger. Full flexibilityThe CS ONE is fully compatible with the batteries of cars, motorcycles, leisure vehicles, vans and boats (all types of lead-acid and lithium-ion batteries). Its number plate is the absolute user-friendliness, which makes it unnecessary to select modes â simply connect the CS ONE to your vehicle battery and it does the rest. This makes the CS ONE the absolute leader for charging, conditioning and maintenance of batteries worldwide. It offers innovative technology and comfort: So much so that it can remain connected to the battery for as long as you want â with the certainty that the vehicle is ready to start at any time.
