I good strong charge is good for a battery, it stirs the aid up. Never run your trailer on just batteries unit the lights are getting dim, as you are way below 50% charge and damaging the batteries. While you have 220 AH, only 110 are really usable without damage to the batteries.
Here is a good start in learn more about batteries. There is a part two also.

That is some GREAT info Chris! I can't thank you enough!!
I haven't read part 2 yet, but I did check em with a good volt ohm meter when I got them home and based on his open circuit charge chart, I now know that my brand new batteries are between 50 and 75% charged....even though I thought they were nearly fully charged at 6.17 and 6.22 v.
For a few hours last night I had one of em on my 35 year old 6 amp battery charger and made some progress but now that I've read this, I may hafta look into getting a better charger. I dunno about integrating one into the trailer...yet...but a stand alone one could work for my other vehicles if needed.
Thanks again!
Dave
