Battery disconnect switch rated current: 240A, rated voltage: 12V, standby power consumption: 3mA, power-off threshold: 11.8V±0.2V, instantaneous current: 500A. This disconnect switch helps prevent car battery drain due to long-term parking, line aging, or leaving lights on. It helps preserve battery power, providing effective protection and extending battery life. When the battery voltage drops below 11.8V, the remote disconnect switch automatically cuts off power after 120 seconds to conserve energy. When voltage exceeds 13.5V, remote control is disabled to prevent accidental disconnection while driving; operation is then only possible via the manual switch. If the voltage is below 11.8V, the remote switch will automatically disconnect power after 120 seconds. When voltage rises above 13.2V, remote control is disabled for safety during operation, and power can only be controlled manually. This 12V smart battery disconnect switch helps prevent power loss from extended parking, faulty electronics, wire aging, or forgotten lights, helping to protect and extend the life of your car battery.
