[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 forgetting to turn off the lights. 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 voltage falls below 11.8V, the remote termination switch automatically disconnects power after 120 seconds to save energy. If the 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] Using this car battery disconnect switch helps prevent power loss caused by extended parking, electronic device inefficiencies, wire aging, or leaving lights on. It effectively protects and extends the life of the car battery.
