CTEK CS ONE Adaptive Battery Charger and Maintainer

Stress-free, safe and secure battery charging and conditioning

This is the ONE battery charger capable of delivering a whole new dimension of smartness and simplicity. The CTEK CS ONE Adaptive Battery Charger and Maintainer with APTO (Adaptive Charging) Technology does all the thinking for you – you don't even have to worry about which clamp goes where! This is the easiest charger you'll ever use. Add in dedicated app control, to unlock additional features and you've got the most advanced charger available today. Super simple and super smart.

APTO Technology automatically recognises the type of battery you're using, and then automatically delivers a customised charging program, telling you how long until the battery is charged and ready to go. No buttons to press or modes to select – just connect the CS ONE to any 12V battery and simply charge. Polarity free clamps mean you don't even need to worry about which clamp goes where, so you'll never make a wrong connection again. The clamps are spark free too, so don't worry if you accidentally touch them together.

Unlock additional features using the Bluetooth enabled CTEK App. Select 'RECOND' to restore and recondition your battery. Choose 'WAKE UP' for lithium batteries with under voltage protection or to bring deeply discharged lead-acid batteries back to life. Select 'SUPPLY' to turn the CS ONE into a useful 12V supply. You can also monitor the voltage and amps being delivered by the charger.

Super Smart and Super Simple
No buttons to press or modes to select – simply connect to any 12V lead-acid or lithium (LiFePO4) battery and leave it to do its work.

Adaptive Charging Technology (APTOTM)
Automatically works out what type and size of battery you've got and what it needs, then delivers a customised charging programme with the most appropriate charge.

Polarity-Free Clamps
Just put one clamp on each charging point and the CS ONE will automatically work out which is the positive and which is the negative terminal.

Bad Cell Detection
The CS ONE can tell if your battery can't be charged – and will notify you.

Easy to Understand Display
Countdown indicator shows when you can restart your vehicle and how long to go until fully charged.
