[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 the car battery from draining due to long-term parking, line aging, or leaving lights on. It helps preserve car battery power, providing effective protection and extending battery life. [Smart car disconnect switch 12V] When the battery voltage drops below 11.8V, the remote termination switch automatically cuts off power after 120 seconds to conserve energy. When the voltage exceeds 13.5V, remote control is disabled to prevent accidental power disconnection while driving; operation is then only possible via the manual switch. [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 rises above 13.2V, remote control is disabled to avoid unintended shutdown during vehicle operation; power can only be controlled using the button on the switch. [Protect the Battery] This car battery disconnect switch helps prevent power loss caused by extended parking, electrical faults, wire aging, or leaving accessories on. It effectively protects the battery and extends its lifespan.
