Switch [Specifications] Battery disconnect switch rated current: 240A, rated voltage: 12V, standby power consumption: 3mA, power-off threshold: 11.8V ± 0.2V, instantaneous current: 500A. [Manual and Remote Control] This disconnect switch helps prevent car battery drain caused by long-term parking, electrical line aging, or leaving lights on. It helps preserve battery charge, providing effective protection and extending battery life. [Smart Car Disconnect Switch 12V] When battery voltage drops below 11.8V, the remote disconnect switch automatically cuts power after 120 seconds to conserve energy. When voltage exceeds 13.5V, remote control is disabled to prevent accidental power disconnection while driving; operation is then limited to the manual switch. [Automatic Cut-Off] If battery voltage falls below 11.8V, the switch automatically disconnects power after 120 seconds to save energy. When voltage rises above 13.2V, remote functionality is disabled to avoid unintended shutdown during vehicle operation; power can only be controlled via the switch button. [Protect the Battery] This car battery disconnect switch helps prevent unnecessary power loss due to extended parking, faulty electronics, worn wiring, or forgetting to turn off lights. It provides reliable protection and helps extend the lifespan of your car battery.
