[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 can prevent the car battery from being drained due to long-term parking, line aging, or leaving lights on. It helps preserve car battery charge, effectively protecting and extending battery life. [Smart car disconnect switch 12V] When the battery voltage drops below 11.8V, the remote disconnect switch automatically cuts off power after 120 seconds to conserve energy; when voltage exceeds 13.5V, remote control is disabled to prevent accidental disconnection while driving, allowing control only via the manual switch. [Automatic cut-off] If the voltage falls below 11.8V, the remote disconnect switch will automatically cut off power after 120 seconds to save energy. When voltage rises above 13.2V, remote control is disabled to avoid unintended power interruption during operation, and power can only be controlled using the button on the switch. [Protect the Battery] Using this car battery disconnect switch helps prevent drain caused by extended parking, faulty electronics, wire aging, or leaving lights on. It effectively protects and extends the life of the car battery.
