Which should be number one, the " car" battery, or the " cranking "
battery?

If you're going to have two batteries, I'd get used to calling one
"start" or "cranking" as you say and the other is the "house" battery,
or that which gets used for all else other than cranking.

I think cranking is #1 and house is #2
