Battery disconnect switch with a rated current of 240A, rated voltage of 12V, standby power consumption of 3mA, power-off threshold of 11.8V0.2V, and instantaneous current of 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, providing effective protection and extending battery life. Smart 12V car disconnect switch automatically cuts off power after 120 seconds when battery voltage drops below 11.8V to conserve power. When voltage exceeds 13.5V, remote control is disabled to prevent accidental disconnection while driving; operation reverts to manual switch control only. Automatic cutoff feature activates when voltage falls below 11.8V, disconnecting power after 120 seconds. Remote control is disabled when voltage rises above 13.2V to avoid unintended shutdown during vehicle operation; power can then only be controlled via the manual switch button. Helps protect the battery from unnecessary discharge due to extended parking, faulty electronics, wire degradation, or forgetting to turn off electrical loads. Provides reliable battery protection and extends service life.
