[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 car battery drain 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 battery voltage drops below 11.8V, the remote 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; operation is then only possible via the manual switch. [Automatic cut-off] If voltage falls below 11.8V, the remote switch automatically disconnects power after 120 seconds to save battery. 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 from extended parking, electrical faults, wire degradation, or forgetting to turn off lights. It effectively protects and extends the lifespan of your car battery.
