Battery disconnect switch with a rated current of 240A, rated voltage of 12V, standby power consumption of 3mA, power-off threshold of 11.8V±0.2V, and instantaneous current capacity of 500A. This disconnect switch helps prevent car battery drain caused by long-term parking, electrical line aging, or leaving lights on. It assists in preserving battery charge, offering effective protection and extending battery lifespan. When the battery voltage drops below 11.8V, the remote disconnect switch automatically cuts off power after a 120-second delay to conserve energy. When the voltage exceeds 13.5V, remote control functionality is disabled to prevent accidental disconnection while driving; operation can then only be performed using the manual switch. If the voltage remains below 11.8V, the remote switch will automatically disconnect power after 120 seconds. When voltage rises above 13.2V, remote control is disabled for operational safety, and power can only be controlled manually. This 12V smart battery disconnect switch helps prevent power loss due to extended parking, malfunctioning electronics, wire degradation, or lights left on, aiding in the protection and longevity of your vehicle's battery.
