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 of 500A. This 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 remote battery disconnect switch automatically cuts off power after 120 seconds when battery voltage drops below 11.8V to conserve energy. 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 cut-off feature disconnects power after 120 seconds if voltage falls below 11.8V to save battery power. When voltage exceeds 13.2V, remote control is disabled to avoid unintended power-off during vehicle operation; power can only be controlled using the switch button. Helps protect the battery from drain due to extended parking, faulty electronics, wire aging, or lights left on. Designed to enhance battery performance and longevity.
