Product Information

About this item

• [Universal OBD2 Battery Replacement Support] The Creator CBT-20 is specifically designed to maintain power to your vehicle's Electronic Control Unit (ECU) during battery replacement, ensuring critical data and settings are preserved. Its enhanced design features simultaneous voltage and current monitoring, along with comprehensive protection against over-voltage, over-current, and reverse polarity connections.
• [Simultaneous Voltage & Current Display] Equipped with an integrated CPU-powered management system, this OBD lead provides real-time readings of both battery voltage and current. This feature helps prevent the use of depleted backup batteries and allows for the assessment of static current (parasitic drain) while the vehicle is stationary.
• [Advanced Safety Protections] Your vehicle's electronics are safeguarded by robust protection mechanisms. The CBT-20 includes a 3A fast-blow fuse and an automatic cut-off system that activates if the voltage exceeds 16V. It offers reliable defence against over-current, over-voltage, and incorrect polarity connections.
• [Preliminary Leakage (Parasitic Drain) Detection] This tool enables a preliminary assessment of electrical leakage in your car's circuit. By removing a fuse from the vehicle's fuse box and monitoring the current flow, you can identify potential drainage issues. Please note: This device is intended for initial evaluation only; comprehensive diagnostics may require specialised professional tools.
• [Simple and User-Friendly Operation] Securely attach the power clamps to your backup battery terminals (Red to Positive '+', Black to Negative '-'). The screen will display the voltage if connected correctly.Plug the device's OBD connector into your vehicle's OBD port. Once connected, the screen will show the current data. Proceed to remove the old battery and install the new one without losing ECU memory.
• [Important Safety Instructions] Ensure the vehicle ignition is OFF, doors are closed, lights are off, and all electrical appliances are disabled during the battery replacement process. The device operates within a voltage range of 10V to 14V. An alarm will trigger if the voltage drops below 10V or rises above 14V. Cut-off Protection: The power supply will automatically disconnect if the voltage exceeds 16V. Usage Warning: Do not connect car batteries in parallel. The ECU must not be connected to the same battery as the power source during this procedure.
