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.
Oh, I see what you read. I saw it perfectly but stated it badly. I should have said "just connect the +[of the charger] to the + of the first battery and the -[of the charger] to the - of the second battery.

Furthermore, the +'s are to the primary hot lead and the -'s are to the frame ground lead since "battery 1" or "first battery" are also ambiguous.

English is such a crappy language for technical specifications.
