So I checked voltage and I have 10.46 on each of the batteries. Sounds dead, right? When I turn on one little ceiling light and the little porch light it drops to 9.95. However, when put on the battery charger (completely out of RV) they appeared to charge easily and indicated a full charge. (Obviously not correct).
Most likely: Your batteries are totally shot. Maybe the set in the truck too.
Normal no-load float is 12.6-12.8 at 100 percent charged.
12.0 is about 50 percent discharged.
It takes about 13.4 to give them any significant charge at all.
A healthy charge needs above 14.
You probably should try a different charger but don't get your hopes up too high. You have checked the liquid level.....right ??
After you get new batteries, you need to check charging voltages again.
