12V 240A Remote Battery Disconnect Switch, Automatic Power Off Switch Battery disconnect switch rated current: 240A, rated voltage: 12V, standby power consumption: 3mA, power-off threshold: 11.8V ± 0.2V, instantaneous current: 500A. This disconnect switch helps prevent car battery drain caused by long-term parking, aging wiring, or leaving lights on. It maximizes battery power retention and helps protect and extend the life of the car battery. When the battery voltage drops below 11.8V, the remote disconnect switch automatically cuts off power after 120 seconds to conserve energy. When the voltage rises above 13.5V, remote control is disabled to prevent accidental shutdown while driving; operation can then only be done manually via the switch button. If the voltage is lower than 11.8V, the system will automatically disconnect power after a 120-second delay. At voltages above 13.2V, remote functionality is disabled for safety during vehicle operation, and control reverts to the manual switch. This battery disconnect switch helps reduce parasitic drain from issues such as faulty electronics, aging circuits, or forgotten accessories, offering reliable protection for your vehicle's battery.
