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 caused by long-term parking, line aging, or forgetting to turn off lights. It helps preserve battery power, providing effective protection and extending battery life. Smart car disconnect switch for 12V systems: when 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 power disconnection during operation; only manual control remains active. Automatic cutoff feature: if voltage falls below 11.8V, the remote switch disconnects power after 120 seconds. When voltage rises above 13.2V, remote function is disabled to avoid unintended disconnection while driving; power can only be controlled manually via the switch button. Helps protect the battery by reducing power loss from long-term parking, faulty electronics, aging wiring, or leaving lights on. Designed to enhance battery performance and longevity.
