That is, if you are charging them with a 12V charger.
You do not want to charge a single 6V battery with a 12V charger.
Also note, a fully charged automotive battery contains 2.5V per cell. If you measure the voltage on a fully charged battery not connected to the electrical system, it should measure 15V.

That's what I said. Battery pic:
