5. Operating Instructions
The CTEK Comfort Indicator Eyelet M8 features a simple LED 'traffic light' system to show the battery's charge status:
- Green Light: Indicates the battery charge is above 80%. The battery is in good condition and does not require charging.
- Yellow Light: Indicates the battery charge is above 60% but below 80%. The battery should be charged soon.
- Red Light: Indicates the battery charge is below 60%. The battery requires immediate charging.
To charge your battery, simply connect your compatible CTEK charger (up to 10A) to the quick connector of the indicator eyelet. Once charging is complete, disconnect the charger and replace the protective end cap on the eyelet connector.
6. Maintenance
The CTEK Comfort Indicator Eyelet M8 requires minimal maintenance. Periodically inspect the eyelet connections to the battery terminals to ensure they remain clean and secure. Check the cable for any signs of wear or damage. Keep the quick connector clean and ensure the protective end cap is in place when not connected to a charger to prevent dirt and moisture ingress.
7. Troubleshooting
- No LED Indication:
- Check if the eyelet connectors are securely attached to the battery terminals.
- Verify the battery has sufficient voltage (above approximately 3V) for the indicator to function.
- Inspect the inline fuse. If blown, replace it with a fuse of the same rating (typically 15A).
- Incorrect LED Indication:
- Ensure the battery is a 12V lead-acid type. This indicator is not designed for other battery chemistries or voltages.
- Confirm the battery terminals are clean and free of corrosion, which can affect voltage readings.
- If the issue persists, consult a professional or contact CTEK support.
