Setup Guide
Follow these steps to safely connect your BYGD battery charger to a battery:
- Prepare the Battery: Ensure the battery terminals are clean and free of corrosion. If necessary, clean them with a wire brush and a baking soda/water solution.
- Connect to Battery: First, connect the RED positive (+) clamp to the positive battery terminal. Then, connect the BLACK negative (-) clamp to the negative battery terminal. For vehicles, connect the negative clamp to the vehicle chassis away from the battery and fuel line if the battery is still in the vehicle.
- Connect to Power: Plug the charger's AC power cord into a standard 120V AC electrical outlet.
- Select Mode: Press the 'MODE' button on the charger to select the appropriate charging mode for your battery type (see Operating Instructions section).
- Monitor Charging: The indicator lights will show the charging progress. The charger will automatically switch to maintenance mode once the battery is fully charged.
- Disconnect: Once charging is complete, first unplug the AC power cord from the outlet. Then, disconnect the BLACK negative (-) clamp, followed by the RED positive (+) clamp.

Operating Instructions
Charging Modes:
The charger features multiple charging modes to accommodate various battery types. Press the 'MODE' button repeatedly to cycle through the available modes:
- 6V Mode: For 6-volt lead-acid batteries.
- 12V Mode: For 12-volt lead-acid batteries (Normal, Dry-load, Maintenance-free, CA, Wet).
- 12V AGM Mode: Specifically for 12-volt AGM batteries.
- 12V Lithium Mode: For 12-volt lithium-ion batteries with BMS protection.
- 12V Repair Mode: Uses pulse repair technology to help desulfate and restore slightly damaged 12V lead-acid batteries.
- Low Voltage Repair Mode: Used to charge batteries below 1 volt.
The charger has a memory function, meaning it will return to the last selected mode upon restart, making it convenient for recurring use.
Indicator Lights:
The indicator lights on the charger provide crucial information about the charging process:
- Battery Percentage Lights: Indicate the current charge level of the battery (e.g., 25%, 50%, 75%, 100%).
- Charging Mode Lights: Illuminate to show the currently selected charging mode (e.g., 6V, 12V, AGM, Lithium, Repair).
- Error Lights: Signal potential issues such as reverse polarity, overcharge, or other malfunctions. Refer to the Troubleshooting section for details.
