Select 12V for standard passenger vehicles and other 12V battery systems. Select 24V only for vehicles or equipment that use a 24V battery system, such as certain trucks, commercial vehicles, or specialty applications. Always match the switch voltage to your vehicle’s actual battery system before installation.

Install the relay switch at the battery terminal area following the included instructions and hardware guidance. Use the remote to disconnect battery power when the vehicle will be parked for an extended period, then reconnect power before normal vehicle use. Confirm that your vehicle’s electronics, alarm system, radio memory, and other settings can tolerate battery disconnection, as some systems may reset when power is cut. If you are unsure about compatibility or wiring, have the unit installed by a qualified automotive technician.
