Charging batteries is now even easier with the CTEK CS ONE. APTO™ adaptive charging technology simply takes care of everything - you don't even have to think about which terminal to connect where! It's the easiest charger you'll ever use. With the special app control to unlock additional features, this is the most advanced charger on the market today. Super simple. Super smart. Simply CS ONE.

Groundbreaking adaptive battery charger and maintenance device

APTO™ technology automatically detects the battery type and then activates the appropriate charging program, displaying the remaining charging time until it is ready for use. No buttons, no modes - simply connect the CS ONE to any 12 V battery and charge. The polarity-free terminals save you having to think about which terminal to connect where. No more wrong connections. The terminals are also spark-protected. If they do accidentally touch each other, nothing will happen. Additional functions can be activated using the CTEK app with Bluetooth®. Select RECOND to restore and recondition the battery. Select WAKE UP for lithium-ion batteries with undervoltage protection, or bring deeply discharged lead-acid batteries back to life. Select SUPPLY to turn the CS ONE into a practical 12 V source. The voltage and current supplied by the charger can also be monitored.
