Switch [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, aging wiring, 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 energy. When voltage exceeds 13.5V, remote control is disabled to prevent accidental shutdown during vehicle operation; power can then only be controlled manually via the switch button. [Automatic Cut-Off] If voltage falls below 11.8V, the remote switch automatically disconnects power after 120 seconds to save battery. When voltage rises above 13.2V, remote functionality is disabled to avoid unintended disconnection while driving; control reverts to the manual switch button. [Protect the Battery] This car battery disconnect switch helps prevent unnecessary power loss due to extended parking, electrical system faults, wire aging, or forgotten accessories. It effectively protects and extends the lifespan of your vehicle's battery.
