DISPLAY EXPLANATION
The circling white light on the CS ONE shows that the charger seeking/analyzing the battery. If this process takes longer than 60 seconds, it is an indication of poor contact between the battery and the charger - or a battery’s drained too low (<1,5V for lead acid and a lithium that has closed-down, Under Voltage Protection).
Charging indicator (START, >8, 6, 4, 2, 1h). Indicates which stage the charger is in during the charging process.
When the battery is fully charged, the CS ONE will automatically go into CARE mode and maintain a safe charge.
The CARE mode is shown by all lights on the LED indicator pulsing.
During the first two minutes indicators (>8 and 2) will blink blue. This indicates that the charger is ready for pairing with the CTEK app . Please note that the app is only required for extra features as WAKE UP, SUPPLY and RECOND.

CS FREE
TROUBLESHOOTING
The CS FREE is stuck at ¼ light when charging
- This could mean that the internal battery has gone into UVP (Under Voltage Protection). There’s various reasons to why this happens. The main reason why is that the CS FREE has been left unattended for too long.
- It takes approximetely 60 minutes to charge a CS FREE from 0-100%.
If your CS FREE has this issue, it counts as defective.
For warranty inquiries, please contact your retailer to initiate a replacement claim.
The CS FREE is fully charged but it doesn’t charge the connected battery.
- Make sure the battery has at least 3V of charge.
- Make sure the clamps have good connection with the terminals.
- Check the charging cables for cracks and other defects.
- Check the pins for the connector on both the charging cable and the charger.
- Make sure the connector is seated properly in the charger.
If the issue persists, try connecting a different known good battery. If there is no difference in the behaviour, and all the above is OK, the charger might be defective.
For warranty inquiries, please contact your retailer to initiate a replacement claim.
