Batteries not charging.

I have a Lance 950, 2012. Seems like since I have owned it, I have had problems with adequate battery power. One night of CPAP draining both batteries?

I added a second Interstate, so I am running two, both less than two years old.

When I run off of shore power, everything works, but as soon as I disconnect, the batteries are near dead.

When I installed the second battery I duplicated the first..in other words, all the negative cables went to one post, positive to the other post, both posts outside the battery box.

When I installed the second battery, I just ran the cables from the new battery to the same posts the first battery were connected to, I did not run from battery B to battery A, then to the posts, I guess what I am saying is that I did not run them in sequence, but rather independent to those posts outside the battery boxes.

Today I used shore power to fire up the generator and let it run for almost 45 minutes. At first when I shut the generator down, the battery gauge (which I understand isn't the most accurate) read full. Two attempts to restart the generator on battery power, proved still not enough juice, then the battery gauge dropped right back to 25%

I guess my next step is to pull the batteries and have them checked down at the auto parts store. I did pull them a month ago and checked the water level, and they were both good. Hard to believe that two interstates would go bad in less than two years?

Man this is getting frustrating, I bought new so everything would work!
