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 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 battery 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 is then limited to the manual switch. If voltage falls below 11.8V, the remote switch will automatically disconnect power after 120 seconds. When voltage rises above 13.2V, remote control is disabled for safety during operation, and power can only be controlled via the manual button. This battery disconnect switch helps prevent power loss due to extended parking, faulty electronics, wire aging, or forgotten lights, effectively protecting and extending the life of your car battery.
