[Specifications] Battery disconnect switch rated current: 240A, rated voltage: 12V, standby power consumption: 3mA, power-off threshold: 11.8V0.2V, 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 battery charge, providing effective protection 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 the voltage exceeds 13.5V, remote control is disabled to prevent accidental disconnection while driving; operation can only be performed manually via the 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 manual button on the switch.
