Battery disconnect switch rated current: 240A, rated voltage: 12V, standby power consumption: 3mA, power-off threshold: 11.8V0.2V, instantaneous current: 500A. This disconnect switch helps prevent car battery drain caused by long-term parking, aging wiring, or leaving lights on. It helps preserve battery charge, offering effective protection and extending battery life. Smart car disconnect switch for 12V systems: When battery voltage drops below 11.8V, the remote switch automatically cuts off power after 120 seconds to conserve battery. When voltage rises above 13.5V, remote control is disabled to prevent accidental disconnection while driving; operation is then only possible via the manual switch. Automatic cutoff feature: If battery voltage falls below 11.8V, the remote switch disconnects power after 120 seconds. When voltage exceeds 13.2V, remote function is disabled to avoid unintended power loss during vehicle operation; control reverts to the manual switch button. Helps protect the battery by preventing unnecessary discharge due to extended parking, faulty electronics, wire degradation, or forgotten accessories. This device supports battery maintenance and longevity.
