Safety Information

⚠️ Please mind potential fire risk and strictly follow the instruction manual for charging and storage.

• Charger is designed for 12V batteries only.
• Ensure that the cables are properly selected for the batteries being charged.
• Before disconnecting the battery, turn off all receivers connected to it, and then disconnect the battery from the circuit.
• Only use rechargeable batteries with this device.
• Never attempt to charge a frozen or physically damaged battery.

Setup and Connections

1. Identify Components: Familiarize yourself with the charger's ports and switches.



2. Connect to Battery:
   • Connect the red (+) alligator clip to the positive terminal of the battery.
   • Connect the black (-) alligator clip to the negative terminal of the battery.
   • Ensure a secure connection.
3. Connect to Power: Plug the power cable into the AC IN port on the charger, then plug the other end into a suitable wall outlet (180-260V AC).
4. Power On: Flip the ON/OFF switch to the 'ON' position.

Operating Instructions

Intelligent 3-Stage Charging Process

The Monolith smart charger utilizes an intelligent 3-stage charging process that adjusts voltage and current based on the battery's state of charge. The current charging stage is indicated by LEDs on the charger.

1. Stage 1: BULK (Constant Current)
   • The charger identifies the battery and its needs.
   • Charges the battery up to approximately 80% of its capacity.
   • Maximum current is kept constant, and voltage is high.
2. Stage 2: BOOST (Constant Voltage / Absorption)
   • The charging voltage is kept constant between 14.1VDC and 14.8VDC.
   • The charging current gradually reduces.
3. Stage 3: FLOAT (Maintenance)
   • The battery reaches 95% to 100% of its capacity.
   • The charging voltage is reduced to a constant value between 13.0VDC and 13.8VDC.
   • The charging current automatically drops to 0A once the battery is fully charged, maintaining it at optimal levels.

LED Indicators and Mode Selection

The charger features LED indicators to show the selected battery type and the current charging stage. Use the 'MODE' button to cycle through battery types and the 'WAKE UP' button for specific functions (refer to detailed instructions for specific battery types if provided in the full manual).

Maintenance

• Keep the charger clean and free from dust and debris.
• Ensure the ventilation fan is not obstructed to prevent overheating.
• Store the charger in a dry, cool place, away from direct sunlight and extreme temperatures (Working Temperature: 0°C ~ +40°C).
• Regularly check the cables and connectors for any signs of wear or damage. Replace if necessary.
• The intelligent charging system helps prevent overcharging, but it's good practice to monitor the charging process.

Troubleshooting

The Qoltec Monolith Smart Charger is equipped with multiple safety protections to prevent common issues:

• No Power/Not Charging:
  • Check if the power cable is securely plugged into both the charger and the wall outlet.
  • Ensure the ON/OFF switch is in the 'ON' position.
  • Verify the wall outlet is functional.
  • Check for any blown fuses in the AC input (USE ONLY WITH A 250V FUSE).
• Charging Interrupted/Error Indicator:
  • Short-circuit protection (SCP): Disconnect the charger, check for short circuits in the battery connections, and reconnect.
  • Overheating protection (OTP): Ensure the ventilation fan is clear and the charger is in a well-ventilated area. Allow it to cool down.
  • Overcurrent protection (OCP): This indicates too much current is being drawn. Check battery condition.
  • Low voltage protection (UVP): The battery voltage might be too low for the charger to initiate charging safely.
  • Surge protection (OVP): Protects against excessive input voltage.
  • Reverse Polarity Protection: If the battery clips are connected incorrectly (+ to -), the charger will not operate. Correct the connections.
  • Ensure the battery is not frozen or damaged, as the charger will not attempt to charge such batteries.

Specifications

User Tips

• For optimal battery life, ensure you select the correct battery type using the 'MODE' button before initiating charging.
• Always connect the charger to the battery first, then to the AC power source. Disconnect in reverse order (AC power first, then battery).
• If charging a battery that has been deeply discharged, the 'WAKE UP' function (if applicable for your battery type) might be necessary to initiate the charging cycle.
• Consider the application: This charger is suitable for various 12V battery applications, including RVs, camping setups, and boats.
