4. Setup
Before connecting the charger, ensure the battery terminals are clean and free of corrosion. Always connect the charger to the battery before plugging it into an AC outlet.
4.1 Connecting to the Battery
The Banshee Smart Charger includes two types of connectors: alligator clips and ring terminals. Choose the appropriate connector for your application.
- Alligator Clips: Ideal for temporary connections or batteries with easily accessible terminals.
- Ring Terminals: Suitable for semi-permanent installations, providing a secure connection.
To connect:
- Ensure the charger is unplugged from the AC power source.
- Connect the positive (+) red connector to the positive (+) battery terminal.
- Connect the negative (-) black connector to the negative (-) battery terminal.
- For vehicles, if connecting to the chassis, connect the negative (-) clamp to a metal part of the chassis away from the battery and fuel line.
- Once connected to the battery, plug the charger into a suitable AC electrical outlet.

5. Operating Instructions
The Banshee Smart Charger features an intuitive interface with a display and a 'MODE' button to select the desired charging program.
5.1 Selecting a Charging Mode
After connecting the charger to the battery and plugging it into an AC outlet, the charger will typically default to a standard mode or perform an initial battery analysis. Press the 'MODE' button to cycle through the available charging programs:
- 6V STD: For 6 Volt Standard Wet/Flooded Lead Acid Batteries.
- 12V STD: For 12 Volt Standard Wet/Flooded Lead Acid Batteries.
- 12V AGM/C: For 12 Volt Absorbed Glass Mat (AGM) Lead Acid Batteries. This mode may also include a cold weather charging setting.
- 12V LFP: For 12 Volt LiFePO4 (Lithium Iron Phosphate) Batteries.
- Maintenance (12V M): A low-current mode to keep a fully charged battery at optimal levels, preventing self-discharge.
- Recondition/Desulfator (RECOND): A specialized mode designed to recover deeply discharged or sulfated batteries by applying a controlled high-voltage pulse. Use with caution and only when necessary.
- Supply (12V): Provides a constant 12V power supply, useful for powering 12V accessories or maintaining vehicle electronics during battery changes.
The charger's display will indicate the selected mode, current battery voltage, and charging status. The charger will automatically switch off once the battery reaches a full charge, preventing overcharging.
