Most often when a deep cycle battery gets discharged below 50% charge (apprx 12.0VDC) and do not get re-charged back up right away they will start self destruct inside the battery...
You need to have a multimeter reading the battery terminals when you are charging as also sometime when a battery is really low the battery charger will kick off and not keep appling DC charging voltages. Sometimes this has happened to me and I had to start out with a lower charging setting (like maybe 2AMPS) and sort of work my way up in small steps to keep the charger from kicking off.
A couple of weeks of trailer lights left turned ON is probably a death warrant for your two 6V batteries. When all re-chargiing fails of course take them back and maybe you can work out a replacement deal with costco. They sell alot of Golf Cart batteries... I don't believe they are at fault however based on your failure description.
Try lower charging setting and use a multimeter across the battery terminals and make sure it stays in charge mode for a couple of hours and hopefully the batteries will start returning to normal... I don't know anything about our brnd of charger but it would probably work better if you could each 6V battery separately. DO NOT however apply 12VDC to the 6VDC battery terminals. I think about 7.5VDC is the norm charging voltage...
Like they always told me at work when I did something like this... "Bend over Braddy" and then each fellow technician gets a free boot shot...
