CS One Battery Charger and Maintenance Device

With the CTEK CS ONE, charging batteries is now even easier. The APTO™ adaptive charging technology takes care of everything – you do not even have to think about which terminal to connect to what! It is the easiest charger you will ever use. With dedicated app controls to unlock additional features, it is the most sophisticated charger on the market today. Super simple. Super smart. Robust design for ease of use and unique rear mounting system for quick connection of CS accessories. Can remain securely connected for extended periods of time during trickle charging. Five-year warranty.

APTO™ technology automatically detects the battery type and then activates the appropriate charging programme, which displays the remaining charge time until the battery is ready for use. No buttons, no modes – just plug the CS ONE into any 12 V battery and charge it. The polarity-free terminals save you having to think about which terminal to connect to what. No more wrong connections. The clamps are also spark-proof. If they do accidentally touch each other, nothing happens. Additional functions can be activated using the CTEK app with Bluetooth®.
