Features: 1.Convenient Operation: Easily kill the car power system with the included remote controller, without having to open the hood. 2.Prevent Battery Drain: Battery leakage can shorten battery life and reduce battery capacity. Protect your battery with our kill switches to easily solve battery depletion problems. 3.Default Off: The remote battery disconnect switch is designed with a default off setting, if the battery were dead ,the device default to closed condition. 4.Low Power Standby: With a standby current of only 5ma, less than 20ma for a new car, this switch is energy efficient and won't drain your battery. 5.Use Note: Turn on the battery before starting the engine (160 ft remote distance); Do not turn off the battery when your engine is working; This remote battery switch is only for battery on or off, it can't start your engine. Specification: Item Type: Remote Battery Disconnect Switch Material: ABS+Copper+Silver Battery Type: CR2016 x1 (one battery for each remote controller) (battery included) Battery Capacity: 75mAh Operating Voltage: DC11-15V Rated Current: 200A Startup Current: 450A (less than ten seconds) Standby Current: 0.005A Operating Instructions Operating Voltage: For 12V vehicles, working voltage range is 11-15V. The 12V and 24V remote battery disconnect switches are not compatible. Most cars, small trucks, and agricultural vehicles use a 12V battery. Choose the corresponding voltage accordingly. Switch Power Consumption: This switch consumes 5mA in standby mode, which is even lower than a new car's power consumption of around 20mA. When the switch is working, it consumes approximately 3W. Use the remote controller to turn off the main power supply by locking the car doors. Note: 1.After installation, the relay switch will increase the battery power consumption after opening, and the total power supply should be turned off with the remote control in time when leaving the car, so as to avoid power loss caused by too long power consumption time and cannot be started. 2. Because cutting off the power supply of the whole car will cause the alarm, the car computer and other power failure can not work, the car needs to be powered off without impact to be used. 3. When driving normally, do not disconnect the relay switch, so as not to increase the generator voltage and damage the car electrical appliances.
