Battery disconnect switch rated current: 240A, rated voltage: 12V, standby power consumption: 3mA, power-off threshold: 11.8V0.2V, instantaneous current: 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 car disconnect switch for 12V systems: when battery voltage drops below 11.8V, the remote switch automatically cuts off 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 only possible via the manual switch. Automatic cutoff feature: if voltage falls below 11.8V, the remote switch disconnects power after 120 seconds. When voltage rises above 13.2V, remote functionality is disabled to avoid unintended power-off during vehicle operation; power can only be controlled using the manual button on the switch. Helps protect the battery by reducing unnecessary power loss due to extended parking, faulty electronics, wire aging, or forgetting to turn off lights. Supports effective battery maintenance and longevity.
