Description 1. Intelligent automatic disconnection: The car remote control battery disconnect switch has an automatic disconnection function. If the battery voltage drops below 11.8V, this function will be activated. It will automatically cut off the power within 120 seconds to save energy. On the contrary, when the voltage exceeds 13.2V, the remote control becomes inactive to prevent accidental power outages while driving, ensuring only manual switch control. 2. Multi functional compatibility: This automatic power off switch is designed for 12V powered vehicles and is compatible with a variety of vehicles, including most cars, trucks, RVs, buses, and trailers, especially vehicles with engine displacement less than 3.0. Its versatility ensures wide applicability and provides reliable power management solutions for various vehicle types. 3. Magnetic lock function: The remote battery disconnect switch uses an innovative relay system based on magnetic principles to control the connection and disconnection of the circuit. Its standby current is only 0.015A, which can significantly improve energy efficiency and make it an ideal solution for optimizing vehicle power management. 4. Easy to install: The remote switch protector is designed for simple installation, directly connected to the negative terminal of the battery to ensure stable performance. Please remember to turn off the engine before installation to ensure a safe and efficient setup process. 5. Enhanced battery protection: By utilizing this leakage protection device, you can avoid unnecessary battery depletion caused by prolonged parking, good electronic device operation, wire degradation, or forgetting to turn off the lights. It effectively protects and extends the service life of vehicle batteries, ensuring that they remain charged and available at all times, ultimately extending the overall service life of the vehicle's electrical system. Specifications: Product size: 83.00x58.00x30.00mm/3.27x2.28x1.18 inches Suitable for SUVs/cars with displacement less than 3.0 Working voltage: 12V Current through: 260A Standby current: 0.015A Instantaneous current: 100A Summary: This series of products is a leak proof switch for automotive batteries, installed on the car battery to solve the problems of battery discharge, leakage, and loss caused by long-term inactivity, circuit aging, battery damage, and other reasons Be careful: 1.When installing this product, please check if the engine is turned off. The inspection switch is also a manual power-off switch. 2.When the engine is started and the battery voltage remains above 13.5V, this product has an automatic protection function (the remote control and password switch are invalid, that is, the battery level cannot be cut off through the remote control). Controller The packaging includes: 1 x Smart Switch 1/2pcs x remote control (with battery)
