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:



+ (connect + tender or charger here)

+
(battery2)
- (connect - tender or charger here)

(Sorry for the primitive graphics, but the forum software removes extra spaces so old-style VT220 graphics don't work)
