5. Safety Information
IMPORTANT WARNING:
- Before charging, ensure the correct battery voltage (6V or 12V) matches the device's selected voltage. Incorrect voltage selection can damage the battery or charger.
- Always connect the charger to the battery terminals correctly: positive (+) to positive (+), and negative (-) to negative (-). Reverse polarity will trigger a fault indicator.
- Do not attempt to charge non-rechargeable batteries.
- Ensure adequate ventilation during charging.
- Keep the charger away from flammable materials.
- Avoid short-circuiting the output cables.
- This charger is designed for lead-acid batteries only. Do not use with other battery types.

6. Setup
- Connect Output Cables: Attach the desired DC output cable (clamp or ring connectors) to the charger's output port. Ensure a secure connection.
- Connect to Battery: Connect the red (+) clamp/ring terminal to the positive (+) battery terminal and the black (-) clamp/ring terminal to the negative (-) battery terminal. Ensure a firm connection.
- Plug into Power: Plug the charger's AC power cord into a standard 100-240VAC wall outlet.
- Initial Check: The charger will perform a self-check. If the 'Fault' LED lights up, check the polarity of your battery connections.

7. Operating Instructions
The charger operates in a fully automatic 4-stage charging process:
- Stage 1: Initialization
When powered on, the charger performs a self-check and detects if the battery is correctly connected. If the 'Fault' LED illuminates, there might be a polarity issue or a severely discharged battery. Verify connections. - Stage 2: Bulk Charge
The charger delivers its highest rated current (1.5A) to the battery until it reaches approximately 80% capacity. During this stage, the '50%' LED will blink, and the '100%' LED will be off. - Stage 3: Absorption
The output voltage is limited to 7.3V (for 6V batteries) or 14.5V (for 12V batteries) while the current gradually declines. This stage charges the battery to its full capacity without overheating. The '50%' LED will be on, and the '100%' LED will blink. - Stage 4: Float
Once the battery is fully charged, the charger switches to float mode. It maintains the battery through pulse charging, ensuring the battery remains at optimal charge without overcharging. Both the '50%' and '100%' LEDs will be on.
LED Indicators
The charger features clear LED indicators to show the charging status:
- 6V Light: On when charging a 6V battery.
- 12V Light: On when charging a 12V battery.
- Fault Light: Flashing indicates a bad battery or incorrect connection.
- Battery Icon (below 50%): Lighting indicates charging below 50% capacity.
- Battery Icon (above 50%): Light on indicates charging above 50% capacity.
- Battery Icon (below 100%): Lighting indicates charging nearing 100% capacity.
- Battery Icon (100%): Light on indicates the battery is fully charged.

8. Maintenance
- Cleaning: Disconnect the charger from power and the battery before cleaning. Use a dry, soft cloth to wipe the exterior. Do not use harsh chemicals or abrasives.
- Storage: Store the charger in a cool, dry place when not in use. Keep cables neatly coiled to prevent damage.
- Cable Inspection: Regularly inspect the power cord and output cables for any signs of damage, such as cuts or fraying. Do not use the charger if cables are damaged.
- Battery Maintenance: For optimal battery life, ensure battery terminals are clean and free of corrosion before connecting the charger.
9. Troubleshooting
- Charger Not Turning On: Ensure the AC power cord is securely plugged into a live outlet. Check for power at the outlet.
- 'Fault' LED On/Flashing:
- Incorrect Polarity: Disconnect the charger and re-connect the clamps/ring terminals to the correct battery terminals (red to positive, black to negative).
- Bad Battery: The battery may be severely discharged, sulfated, or damaged beyond repair. Consult a professional for battery testing.
- Incorrect Voltage: Ensure the charger is set to the correct voltage (6V or 12V) for your battery.
- Battery Not Charging: Verify all connections are secure. Ensure the battery type is compatible with the charger. Allow sufficient time for charging, especially for larger capacity batteries.
- Overheating: If the charger feels excessively hot, disconnect it immediately. Ensure it is in a well-ventilated area and not covered.
