8A 12V charger. For 3Ah to 180Ah lead-acid (AGM; GEL; EFB; MF; CaCa) and lithium batteries. The CS ONE has APTO™ (Adaptive Charging) technology to recognise the type of battery you want to charge and tells how long it will need to charge it. There are no buttons on the CS ONE; just connect any lead-acid or lithium 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
