Maximizing Battery Performace
APTO™ Technology automatically recognizes the type of battery you’re using, and then automatically delivers a customized 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 12 V supply. You can also monitor the voltage and amps being delivered by the charger.
Revolutionary adaptive battery charger and maintainer. Its revolutionary 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.
