A$314.20
- The most advanced battery charger in the world from leading global brand CTEK.
- Adaptive charging technology (APTO): Automatically delivers customised charging for any 12V battery you connect it to, whatever the size, battery health or type – lead-acid or lithium (12V LiFePO₄).
- Powerful simplicity: No buttons to press or modes to select – simply connect CS ONE to any battery, and to either terminal, and CS ONE will safely do the rest – just set it and forget it!
- Polarity free clamps: The CS ONE’s polarity free clamps automatically recognise positive and negative terminals, so it doesn’t matter which way round you connect them. The clamps are spark free too, so no need to worry if you accidentally touch them together.
- Countdown indicator: No guesswork needed - a ‘countdown’ indicator clearly shows when you can restart a flat battery, and how long there is to go before the battery is fully charged.
- Unlock additional features with CTEK App: Connect the CS ONE to the Bluetooth enabled CTEK App to access additional functions. Select the ‘RECOND’ option to restore and recondition your battery. Choose ‘WAKE UP’ for lithium batteries with under voltage protection (UVP) or to bring deeply discharged lead-acid batteries back to life. Select ‘SUPPLY’ to turn the CS ONE into a useful 12V supply, if you need to replace the battery. Advanced settings enables you to monitor the voltage and amps being delivered by the charger.
- Ambient Temperature Adjustment: Senses whether it’s hot or cold and automatically adjusts the output voltage.
- Sleek design: With a sleek, black, modern design, CS ONE looks as good on the outside as it works on the inside. It will be a stylish addition to your garage.
- 5-year warranty
