wow, i really am going to have to disagree with that statement there.
a deep cycle battery is just another battery technology, which has low memory. the whole purpose of the battery is to start the car,and act as a reserve until the alternator can catch up with the load, which is usually a matter of milliseconds. after that the alternator takes over and supplies the current and voltage to the electrical system. i really dont see how a battery could fry an alternator, would you like to elaborate on that?
i also dont need more than one battery, as i dont use the system whilst the car is not running.
i am curious as to your reasoning behind your thoughts, so please dont assume im bashing or calling you out or anything of the nature.
