Maintenance

• Cleaning: Keep the charger unit clean and dry. Wipe with a soft, damp cloth if necessary. Do not use harsh chemicals or abrasive cleaners.
• Storage: Store the charger in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Inspection: Before each use, inspect the power cord, charging cables, and clamps for any signs of damage, fraying, or corrosion. Do not use the charger if any components are damaged.

Troubleshooting

• Charger Not Turning On:
  Solution: Ensure the charger is securely plugged into a functional mains power outlet. Check the power outlet with another device.
• Reverse Polarity Indicator On:
  Solution: This indicates the positive and negative clamps are connected incorrectly. Immediately unplug the charger from the mains, then disconnect the clamps and reconnect them to the correct battery terminals (red to positive, black to negative).
• Faulty Battery Indicator On:
  Solution: This suggests the battery may be severely damaged or beyond repair. The charger cannot safely charge this battery. Consult a professional for battery assessment or replacement.
• No Charging Progress / Slow Charging:
  Solution: Ensure the correct charging mode (6V or 12V, Standard or Cold/AGM) is selected for your battery type. Check that the battery clamps have a good, clean connection to the battery terminals. For very large or deeply discharged batteries, charging may take a significant amount of time.
• Clamp Indicator On:
  Solution: This indicates a poor or no connection to the battery. Ensure the clamps are securely attached to the battery terminals and that there is no corrosion preventing a good contact.
