Only one has to be bad to cause the converter to want to charge the batteries. Jamie's assertion for 11.5 is easily proofed. Assuming they're wired parallel, which side did the 11.5 come from, or did both read 11.5. If both, something's either seriously wrong, the coach was stored with use/store in the 'Use' position or the batteries are bad. BTW, the second item can and will slowly drain the battery - and eventually kill it. Once a battery is fully dead, the cells are at risk and you may never get it back.
Regardless, take the batteries back out and have them stress tested. Most auto parts chains will do this free of charge. It's the easiest, least expensive place to start. I'd hesitate to take them back to Advance, though taking them to Auto Zone may put dollar signs in their eyes too. Flip a coin.
