    【Important Notes】For electronic devices with a screen that are powered on, the 100% battery level shown on the display does not mean the battery is fully charged. Normally, it takes another 10 to 50 minutes after the screen shows 100% for the battery to reach a full charge. Therefore, in Blue Light Mode with no operation, the power separator will automatically cut off power after 10 to 50 minutes. For other devices without a screen using Green Light Mode, the power will be disconnected after about 5 minutes.

    Potential Mishaps of Not Disconnecting the Car Battery

    When not disconnecting the car battery before charging, you risk the following mishaps:

    • Short circuits that can damage your vehicle’s electrical system and components.
    • Electrical surges may harm the delicate electronics in your vehicle.
    • Safety hazards such as sparks or fires that can occur during the charging process.
    • Inefficient charging, leading to longer charging times and potentially damaging the battery.
    • Personal safety risks due to accidental contact with live electrical components.

    Always remember to prioritize safety and disconnect your car battery before charging to avoid these potential mishaps.

    Steps to Safely Disconnect Car Battery for Charging

    To ensure a safe charging process for your car battery, follow these steps to properly disconnect it:

    • Park your car: Find a flat, stable surface for safety.
    • Locate the battery: Open the hood and identify the battery. It’s usually a rectangular box with two cables connected to it.
    • Identify the terminals: The battery has two terminals – positive (+) and negative (-).
    • Start with the negative terminal: Using a wrench or socket, loosen the nut on the negative terminal cable. It’s usually black and marked with a minus sign.
    • Remove the negative cable: Once the nut is loose, carefully lift the negative cable off the terminal.
    • Repeat for the positive terminal: Follow the same steps for the positive terminal, which is red and marked with a plus sign.
    • Secure the cables: Make sure the cables are placed where they won’t accidentally touch any metal surfaces.
    • Double-check the disconnection: Ensure both cables are completely detached from the terminals.
