Specifications: Battery disconnect switch rated current: 240A, rated voltage: 12V, standby power consumption: 3mA, power-off threshold: 11.8V±0.2V, instantaneous current: 500A. Manual and remote control: This disconnect switch helps prevent car battery drain caused by long-term parking, electrical line aging, or leaving lights on. It helps preserve battery charge, providing effective protection and extending battery life. Smart car disconnect switch 12V: When battery voltage drops below 11.8V, the remote disconnect switch automatically cuts power after 120 seconds to conserve battery; when voltage exceeds 13.5V, remote control is disabled to prevent accidental disconnection while driving, and operation is only possible via the manual switch. Automatic cutoff: If battery voltage falls below 11.8V, the remote switch automatically disconnects power after 120 seconds to save energy. When voltage rises above 13.2V, remote control is disabled to avoid unintended power-off during vehicle operation; power can only be controlled using the manual switch button. Battery protection: This car battery disconnect switch helps prevent power loss due to extended parking, faulty electronics, aging wiring, or leaving lights on.
