[Specifications] Battery disconnect switch rated current: 240A, rated voltage: 6-30V, standby power consumption: 3mA, power-off threshold: 11.8V±0.2V, instantaneous current: 500A. [Manual and remote control] This disconnect switch can prevent the car battery from being exhausted due to long-term parking, line aging, and forgetting to turn off the lights. It can maximize the storage of car battery power, effectively protect and extend life. [Smart car disconnect switch 12V] When the battery voltage is lower than 11.8V, the remote termination switch automatically cuts off the power after 120s to save power; when the voltage is higher than 13.5V, the remote control will be disabled to prevent accidental action to turn off the power while driving, and can only be controlled by the manual switch. [Automatic cut-off] If the voltage is lower than 11.8V, the remote termination switch will automatically cut off the power after 120s to save power, and if the voltage is higher than 13.2V, the remote control will be disabled to prevent accidental action to turn off the power while driving, and the power can only be controlled by the button on the switch. [Protect the Battery] Using this car battery termination switch can avoid power consumption caused by long-term parking, poor electronic equipment, aging of lines, forgetting to turn off the lights, etc. It can effectively protect and extend the life of the car battery.
