Battery disconnect switch with a rated current of 240A, rated voltage of 12V, standby power consumption of 3mA, power-off threshold of 11.8V±0.2V, and instantaneous current capacity 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 energy. When voltage exceeds 13.5V, remote control is disabled to prevent accidental disconnection during vehicle operation; only manual control remains active. Automatic cutoff function disconnects power after 120 seconds if voltage falls below 11.8V. Remote control is disabled when voltage rises above 13.2V to avoid unintended power interruption while driving; power can then only be managed via the manual switch on the device. Helps protect the car battery from unnecessary discharge due to extended parking, faulty electronics, wire degradation, or leaving lights on, thereby supporting longer battery lifespan.
