POWERFUL SIMPLICITY, TOP PERFORMANCE The CS ONE sets new standards in battery charging – it offers top performance while being easy to use for anyone who demands the best. Thanks to the revolutionary, polarity-free APTO™ technology, the CS ONE thinks for you and automatically adjusts its charging to meet the needs of your battery. The Wi-Fi and Bluetooth-connected CTEK app unlocks advanced features and gives you full control over battery maintenance whenever you want. ADAPTIVE BATTERY CHARGING AND MAINTENANCE DEVICE The CS ONE is designed for vehicle owners who expect nothing but the best from a smart battery charger. From the revolutionary APTO™ technology to the black, polarity-free clamps, the CS ONE offers unparalleled user-friendliness and functionality, automatically detecting the battery type, size, and condition to deliver a tailored charging program for your specific battery. The Gen 2 version of the CS ONE offers Wi-Fi and Bluetooth connectivity with the CTEK app, which includes additional features such as RECOND, WAKE UP, and SUPPLY, as well as enhanced charging information. No more guessing, no more frustration. The CS ONE is the ultimate charging solution for those who settle for nothing less than perfection. WHAT'S NEW IN GEN 2? The CS ONE Gen 2 offers several improvements over Gen 1, most notably Wi-Fi connectivity. With the new and improved CTEK app, you can now monitor charging processes remotely, view and export charging history, access comprehensive event logs, receive push notifications, track charging status in real-time, and observe individual charging phases.

USER INTERFACE: LED symbols, smartphone display (User choice) CONNECTIVITY: Wi-Fi (2.4 GHz), BLUETOOTH® LE 5.1, IEEE 802.11 b/g/n APP SUPPORT: CTEK app for Android and iOS BATTERY CHEMISTRY: Lead-acid, Lithium-ion IP CLASS: IP65 COOLING: Natural convection DIMENSIONS (L X W X H): 235 x 88 x 52 mm POWER CORD LENGTH (INPUT): 1.4 m NET WEIGHT (DEVICE WITH CABLES): 0.675 kg WARRANTY: 5 years * The self-discharge current is the current at which the battery discharges when the charger is not connected to the power supply. CTEK chargers have a very low self-discharge current. ** The quality of the charging voltage and current is very important. High current ripple heats the battery, causing the positive electrode to age. High voltage ripple can damage other equipment connected to the battery. CTEK battery chargers produce very clean voltage and very clean current with low ripple.
