Reading voltage between battery terminals

Close-up educational diagram of a single Li-ion cell with two metal terminals labeled “+” and “−”; show the plus terminal slightly higher on a vertical potential scale than the minus terminal, with one arrow labeled “higher electric potential.”

Start with two terminals

A battery has two terminals: plus and minus. The useful fact is not “the plus has voltage,” but “the plus is at a higher electric potential than the minus.”
