Car battery charger CTEK CS ONE

CTEK’s latest charger takes charging to the next level. There’s no need to worry about any setup.

Simply charge any battery in any situation: CTEK’s unique APTO™ (Adaptive Charging) technology for fast and easy charging of any battery. It automatically detects the type and size of your 12V lead-acid or lithium (LiFePO4) battery. It then works out what the battery needs before running a customised charging program to maximise the performance of the connected battery.

Easy to use: No buttons or modes to choose from – simply connect the CS ONE to any battery and let it do its thing.

APTO technology: Adaptive Charging Technology (APTO) detects the type of battery, its capacity and its condition. It then automatically delivers the most suitable charging curve for the battery and shows how much time is left until it is fully charged.

Polarity-free terminals: Both terminals of the charger are black, so you don't have to worry about which terminal to connect to which pole. The CS ONE automatically detects how the terminals on the battery are connected, or switches them internally. So you can't connect the terminals incorrectly.

Time indicator: It clearly shows you when a discharged battery can be used for one start and how long it takes until the battery is fully charged.

More functions via the CTEK app: The app unlocks functions such as "RECOND" to revive deeply discharged batteries, "LITHIUM WAKE UP" for lithium batteries with undervoltage protection (UVP) and "SUPPLY" to convert the CS ONE to a 12V power source.

Temperature sensor: Senses the ambient temperature and automatically adjusts the output voltage.

Automatically detects defective cells: It can detect if the battery cannot be charged and warns you.
