The charger offers seven distinct modes for various battery types and charging needs.

Available Modes:

• 12V STD (Standard Lead Acid): For 12V wet cell, flooded, and maintenance-free lead-acid batteries.
• 12V AGM/C (AGM / Cold Weather): Optimized for 12V Absorbed Glass Mat (AGM) batteries and for charging all 12V lead-acid batteries in cold conditions (below 50°F / 10°C).
• 12V M (Maintenance): A low-current maintenance charge for 12V lead-acid batteries to keep them fully charged during long-term storage.
• 12V LFP (LiFePO4): Specifically designed for 12V Lithium Iron Phosphate (LiFePO4) batteries.
• 6V STD (Standard 6V Lead Acid): For 6V wet cell, flooded, and maintenance-free lead-acid batteries.
• Supply (12V Power Supply): Provides a constant 12V output, useful for powering 12V accessories or maintaining vehicle settings during battery changes.
• Recond (Recondition / Desulfate): A specialized mode for recovering deeply discharged or sulfated 12V lead-acid batteries. Use with caution and only when necessary.

7. Maintenance

Proper maintenance ensures the longevity of your battery and charger.

Charger Maintenance:

• Keep the charger clean and dry. Wipe with a soft, damp cloth if necessary.
• Store the charger in a cool, dry place when not in use.
• Inspect cables and connectors for damage before each use. Replace if frayed or broken.

Battery Maintenance:

• Use the 12V M (Maintenance) mode for long-term storage of 12V lead-acid batteries to prevent self-discharge and keep them at optimal charge.
• The Recond (Recondition / Desulfate) mode can help restore capacity to certain 12V lead-acid batteries that have been deeply discharged or show signs of sulfation. This process can take several hours.

8. Troubleshooting

If you encounter issues with your Banshee Smart Battery Charger, refer to the following common troubleshooting steps:

• Charger Not Turning On:
  • Ensure the AC power cord is securely plugged into a live electrical outlet.
  • Check for tripped circuit breakers or blown fuses in the power supply.
• Battery Not Charging / Error Displayed:
  • Verify that the battery connections (positive and negative) are correct and secure. The charger has reverse polarity protection, which will prevent charging if connections are incorrect.
  • Confirm that the selected charging mode matches your battery type (e.g., 12V STD for standard lead-acid, 12V LFP for LiFePO4).
  • The battery may be severely discharged or damaged. Try the 'Recond' mode for lead-acid batteries if applicable, or have the battery professionally tested.
  • Check if the battery capacity is within the charger's supported range (4-120Ah).
• Charger Overheating:
  • Ensure the charger is in a well-ventilated area and not covered.
  • If overheating persists, disconnect the charger and contact support.
• LCD Display Not Working Correctly:
  • Disconnect and reconnect the charger from the power source to reset it.
  • If the issue persists, contact customer support.
