Description

Keeping a vehicle battery ready for the road can be stressful, but the CTEK CS ONE makes it effortless. This compact charger connects directly to any 12V lead-acid or LiFePO4 battery and takes care of the rest - no buttons, no modes, just a reliable charge every time. Adaptive Charging Technology (APTOTM) reads the battery's type and size, then delivers a custom program that restores capacity and extends lifespan. The polarity-free clamps automatically identify positive and negative terminals, eliminating the guesswork that can lead to costly mistakes. If a cell is weak, the built-in bad cell detection warns you early, so you can replace the battery before it fails. Designed for cars, motorcycles, vans, boats and other leisure vehicles, the CS ONE is a versatile maintenance tool for garages, workshops and on-the-go situations. Its smart, set-and-forget operation saves time and gives peace of mind, ensuring your battery is always at its best when you need it most.

Key Features

Super smart, no buttons - just connect and let CS ONE manage charging automatically, so you can forget about timers, modes or complicated settings.

Adaptive Charging Technology (APTOTM) automatically identifies the battery type and capacity, then applies a customized charging programme that maximizes performance and prolongs service life for both lead-acid and LiFePO4 cells.

Polarity-free clamps sense which clamp is positive and which is negative, so you simply clip them onto any 12V battery without worrying about reverse polarity errors that could damage the charger or battery.

Built-in bad cell detection scans each cell during charging, alerting you to weak or failing cells before they leave you stranded, giving peace of mind and helping you schedule timely replacements.

Works with cars, motorcycles, vans, boats and other leisure vehicles, covering all 12V lead-acid and LiFePO4 batteries, making the CS ONE a single, portable solution for home garages, workshops and on-the-go emergencies.
