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 leaving lights on. It helps preserve battery charge, providing effective protection and extending battery life. Smart car disconnect switch for 12V systems: when battery voltage drops below 11.8V, the remote switch automatically cuts off power after 120 seconds to conserve energy. When voltage exceeds 13.5V, remote control is disabled to prevent accidental disconnection during vehicle operation; only manual control remains active. Automatic cutoff feature: if voltage falls below 11.8V, power is automatically disconnected after 120 seconds. When voltage rises above 13.2V, remote functionality is disabled to avoid unintended shutdowns while driving; power can then only be controlled manually via the switch button. Helps protect the battery from unnecessary discharge due to extended parking, faulty electronics, wiring degradation, or forgetting to turn off electrical loads. Provides reliable battery protection and supports longer battery lifespan. Color: As shown in picture. Material: Metal + Plastic. Package Contents: 1 x Remote Battery Disconnect Switch kit.
