Ctek CS One battery charger

The APTO™ technology automatically detects the battery type and then activates the appropriate charging program, which displays the remaining charging time until readiness. No buttons, no modes – simply connect the CS ONE to any 12V battery and start charging. The polarity-free clamps eliminate the need to think about which clamp goes where. No more incorrect connections. The clamps are also spark-proof, so if they accidentally touch each other, nothing happens. Additional functions can be unlocked via the CTEK app using Bluetooth®. Select RECOND to restore and recondition the battery. Choose WAKE UP for lithium-ion batteries with under-voltage protection or to revive deeply discharged lead-acid batteries. Select SUPPLY to turn the CS ONE into a convenient 12V power source. You can also monitor the voltage and current supplied by the charger.
