Product Description

The CS ONE takes the guesswork out of keeping your 12V battery healthy. Clamp it on either way round and CTEK's APTO adaptive charging reads the battery type, size and condition, then delivers the right 8A charge on its own, with no buttons to press or modes to pick. Pair it with the CTEK app over Wi-Fi or Bluetooth to watch the charge from your phone and unlock RECOND, WAKE UP and SUPPLY. It is safe to leave connected for long stretches, so your rig is ready when the next trip comes around.
