Battery Charger CTEK CS ONE

The simplest charger ever – polarity free!

You don’t even need to worry about which clamp goes where.
With adaptive charging technology, it automatically calculates the optimal way to charge your battery.

Charging current [A]: 8
Charging voltage [V]: 12

Revolutionary adaptive battery charger with maintenance charging.
The APTO™ technology automatically recognizes the type of battery you’re using and then delivers a customized charging program, showing you how much time remains until the battery is fully charged and ready to use.

There are no buttons to press and no modes to select – simply connect the CS ONE to any 12 V battery and start charging.

Thanks to its polarity-free clamps, you never have to worry about connecting it incorrectly – you’ll never make a wrong connection again. The clamps are also spark-free, so there’s no need to worry if they accidentally touch each other.
