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, electrical system aging, or leaving lights on. It helps preserve battery charge and supports battery longevity. When battery voltage drops below 11.8V, the remote switch automatically disconnects power after 120 seconds to conserve energy. 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 is below 11.8V, the system automatically cuts off power after 120 seconds. When voltage rises above 13.2V, remote functionality is disabled for safety during vehicle operation, and power control is managed only by the manual button. This battery disconnect switch helps reduce parasitic drain from issues such as extended parking, faulty electronics, worn wiring, or lights left on, helping to protect and extend the life of your car battery.
