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 switch automatically disconnects power after 120 seconds to conserve battery. When voltage exceeds 13.5V, remote control is disabled to prevent accidental disconnection during vehicle operation; power can only be controlled manually via the switch. Automatic cut-off: If battery voltage falls below 11.8V, the remote switch disconnects power after 120 seconds to save energy. When voltage rises above 13.2V, remote control is disabled to avoid unintended power-off while driving; power control is limited to the manual switch button. Protect the battery: This car battery disconnect switch helps prevent power loss due to prolonged parking, faulty electronics, wire aging, or leaving lights on.
