Features: 1. Magnetic Lock Function: This car battery switch adopts a new type of relay, which uses magnetic principle to control the circuit's disconnection. The standby current is 3mA, which is more energy-saving. LCD display constantly detects battery voltage. 2. More Models: Suitable for 12V DC vehicles, trucks, RVs, trailers, etc. (vehicles with displacement less than 2.0L), not suitable for Alto, Liwei, Sylphy, , , Note: Not recommended for vehicles with a secondary battery or requires decoding, matching, programming, etc. 3. Automatic Disconnection: If the voltage is below 11.8V, the remote termination switch will automatically disconnect the power supply after 120 seconds to save power. If the voltage is above 13.2V, remote control will be disabled to prevent accidental disconnection of the power supply while driving, and the power source can only be controlled through the button on the switch. 4. Easy Installation: The power off switch uses a negative connection to stable performance. Please remember to turn off the power before installation. 5. Battery Protection: Using this car battery disinfection and switch can avoid power consumption caused by long parking, good electronic equipment, aging lines, and forgetting to turn off the lights. It can effectively protect and extend the lifespan of car batteries. Description: 1. Rated Voltage: 12V 2. Rated Current: 200A 3. Current 1500A 4. Standby Current: 0.003A 5.
