For any vehicle that needs to use two batteries where one battery is used for starting the engine, while the other is used to power auxiliary loads. This is a common situation in trucks, boats, RVs, police and rescue vehicles, and in ambulances or fire equipment. A selector switch allows use of the first battery, the second battery, or both batteries simultaneously. This provides back-up starting power in an emergency.
