If your batteries are charging then Check your meter using your car battery to see if it is accurate.

The point is, my 120-12 volt converter is putting out amps, but the voltage output is only 10 volts. I don't understand: in order to charge the batteries -- which it does seem to be doing -- doesn't the voltage output have to be greater than that of the batteries, which varies at times between 12 and 14 volts?

Am I an idiot ... or a big idiot?

My other related question on lighting is this: I am a liveaboard and need more lighting. Should I install 120 volt since I am always on marina-paid shore power when in port; or should I install more 12 volt so that, when sailing, I can use it? Advise anyone.
