This battery cut off switch provides a convenient way to quick disconnect and reconnect power from your battery. The switch provides a solid connection to your car, truck, and other batteries. Turn the knob and the power is disconnected. You can also remove the knob to prevent theft. This battery power disconnect switch also works great to eliminate battery drain if you're storing your vehicle for an extended period of time.
Installation: Remove your negative battery cable, install the disconnect on the negative battery post and then re-attach the vehicle's cable to the post on the disconnect. To break the connection from the vehicle to the battery just unscrew the knob until it loosens up. It would be a good idea to open a door-etc to confirm that the battery is unhooked from the vehicle (no lights come on-etc.) Wear safety glasses during the install.
A very clever device that allows your battery to be isolated from nuisance loads, while the particular equipment is idle/not in use.
Works as described. Exactly what I wanted. Easy install.
The ordering and support provided were top notch and the part was one of a select few that could be used on my vehicle. Installation was so simple, even I could do it! I will gladly order from them again should the need arise.
