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 and can contribute to 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 rises above 13.5V, remote control is disabled to prevent accidental power disconnection while driving; power can only be controlled manually via the switch button. [Automatic Cut-Off] If battery voltage falls below 11.8V, the system automatically disconnects power after 120 seconds. When voltage exceeds 13.2V, remote operation is disabled to avoid unintended shutdown during vehicle operation; control reverts to the manual switch button. [Protect the Battery] This car battery disconnect switch helps reduce parasitic drain from issues such as extended parking, electrical faults, wire aging, or lights left on, helping to protect and prolong the life of the vehicle battery.
