High Quality Material: The core material of this product is copper. Copper offers great electrical conductivity, efficiently transmitting current to ensure stable and smooth power delivery. It is tough and durable, with good ductility and wear resistance, making it resistant to deformation. It can withstand the electrical load of a vehicle battery over the long term, providing reliable and consistent performance and laying a solid foundation for the normal operation of the battery disconnect switch.
Wide Application: Measuring 3.03 x 2.56 x 2.05 inches, this product features a compact design that does not take up excessive space in the vehicle and can be flexibly installed near the battery in various vehicle types. It is highly versatile and compatible with all 12V and 24V vehicles, including common models such as SUVs, sedans, and trucks.
Easy Installation: First, turn off the vehicle’s engine to ensure the vehicle is powered down. Locate the negative terminal of the vehicle’s battery, use a wrench to disconnect the cable from the negative terminal, securely connect the input terminal of the battery disconnect switch to the negative terminal, then reconnect the disconnected negative cable to the output terminal of the switch. Use a wrench to tighten all connections, ensuring they are secure and free of looseness.
