Welcome to the forum. As far the battery--charging system and starter, I'd have to do testing on the vehicle when problem occurs. When the problem occurs, are you saying it won't even crank? If so, there maybe a voltage drop on the starter circuit and the booster just adds a little more voltage. Some people like to do testing, some don't. All I can do is make suggestions on what to test, you have to do the testing.
