Kinda true! lol!
It's been an occasional problem. My dad is a long time (since 1960's) mechanic. We checked the battery in the winter and it was tested fine, at nearly freezing. But corrosion of electrical wiring can become an intermittent problem. So, in this case, my car (a Dodge Charger) has the battery in the trunk, and a heavy wire from the trunk to the engine bay is there. That wire, does have at least one end that is corroded. When I tried to boost with another running car, it refused. So, the belief is, we have to fix primary electrical wiring
So, good guess!
My explanation that the battery "was dead" to my son -- "How many batteries do you need? Can't we just go home and put new ones in? How many do you need?"
