CTEK CS ONE + Free CS ONE Bumper is available from Boating & Outdoors NZ in our Batteries and Charging range for marine, boating and outdoor use.
Key features
• APTO™ (Adaptive Charging) Technology: The charger does all the thinking.
• It automatically detects the battery’s size (Ah), chemistry (Lead-acid or Lithium), and health.
• It then creates a customized charging profile to maximize performance and lifespan without the user needing to press a single button.
• Polarity-Free Clamps: This is a massive safety and convenience feature.
• Both clamps are black because it doesn't matter which clamp goes on which terminal.

Product details
The CS ONE automatically detects the polarity and adjusts itself, making it impossible to "spark" or damage the vehicle’s electronics through incorrect connection.
App-Driven Intelligence: While the unit is plug-and-play, the CTEK App (via Bluetooth/Wi-Fi) unlocks professional features like RECOND (to restore lead-acid batteries), WAKE UP (for "dead" lithium batteries with under-voltage protection), and SUPPLY (to maintain power during a battery swap).

SUPPLY: Turns the charger into a 12V power source, allowing the user to remove the battery without losing vehicle settings (radio codes, seat memory, etc.).
Why Customers Choose CS ONE over Competitors
No Modes to Select: Unlike competitors where you must manually select "AGM" or "Lithium," the CS ONE is fully automatic.
Countdown Timer: It features a unique LED "time-to-go" indicator, telling the user exactly how many hours remain until the battery is ready to start the car and when it is fully charged.
Safe Maintenance: It can be left connected indefinitely ("Connect and Forget") without the risk of overcharging, as it switches to a pulse-maintenance mode once the battery is full.
