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 charge retention and helps protect and extend battery life. When the battery voltage drops below 11.8V, the remote disconnect switch automatically cuts off power after 120 seconds to conserve energy. When voltage rises above 13.5V, remote control is disabled to prevent accidental shutdown during vehicle operation; manual switch control is then required. If the voltage is below 11.8V, the switch automatically disconnects power after 120 seconds. If voltage exceeds 13.2V, remote functionality is disabled to avoid unintended power disconnection while driving; power can only be controlled via the button on the switch. This car battery disconnect switch helps reduce parasitic drain from prolonged parking, faulty electronics, wire degradation, or forgetting to turn off lights, effectively supporting battery protection and longevity.
