Heroes are remembered, but legends never die
some vehicles do idle at 13.7v down 13v when warm and batteries are at a high percent. Some newer vehicles once warm drop to 12.6v but when you rev to 2krpms its comes up to 14.4LOL, Ok, now i get it. I thought that was strange.
I never knew people would actually want there output alt below 13.7. I can't even think of a reason for that on any car???
Lead acid batteries life having a direct relationship to charge voltage and all.
