It helps preserve battery charge, providing effective protection and extending battery life. [Smart car disconnect switch 12V] When the battery voltage drops below 11.8V, the remote switch automatically cuts off power after 120 seconds to conserve energy. When the voltage rises above 13.5V, remote operation is disabled to prevent accidental disconnection while driving; only the manual switch can control the power. [Automatic cut-off] If the battery voltage falls below 11.8V, the remote switch automatically disconnects power after 120 seconds to save energy. When voltage exceeds 13.2V, remote control is disabled to avoid unintended shutdown during vehicle operation; power can only be controlled manually via the switch button. [Protect the Battery] This car battery disconnect switch helps prevent power loss caused by extended parking, faulty electronics, wire aging, or leaving accessories on.
