[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 due to long-term parking, wiring 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 cutoff switch automatically disconnects 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 limited to the manual switch. [Automatic cut-off] If the voltage falls below 11.8V, the remote cutoff switch automatically disconnects power after 120 seconds to save energy. When voltage rises above 13.2V, remote control is disabled to avoid unintended power shutdown during vehicle operation; power can only be controlled via the button on the switch. [Protect the Battery] Using this car battery disconnect switch helps prevent power loss from extended parking, faulty electronics, aged wiring, or leaving lights on. It effectively protects the car battery and extends its lifespan.
