    To add a second battery and have it be functional like a factory second battery, you would need to be a bit of an electrical engineer.

    That being one battery is reserved for starting the vehicle and the other could be run down. But you would still be able to start the vehicle with the other battery, etc.

    BUT if your vehicle had this option from the factory, then all you need to do is get the associated parts and install them. (The factory will have already done all the electrical engineering work for you!) But even so, you would need to know electricity/electronics quite well to properly install this. And you would need a GM Factory Service Manual set which would have the wiring diagrams for all this.

    If you are not an electrical guru type, then best to check around and see if you could find someone to do this for you. Perhaps check with your GM dealer parts/service department and see if a second battery was an option for your vehicle.

    If it was not an option, then might check at auto electric businesses or car stereo businesses and see if they could install a second battery for you.
