My batteries rarely see any discharge. I'm going to have to force it a time or two.
They are T105sand now 8 years old but in good shape. However I'm tired of having to add water every two or three weeks. The Load ocenter is set and is charging properly.The batteries I can use are defined by the size of the T105s, not much as in any room for anything else minus an inch or so of wiggle room. I'm tired of the corrosion too.
Trojan makes a Gel Cell maintenance free and a glass mat...but no one stocks them it seems or any thing else other than the ultra high price Life Line. I don't need cutting edge chemistry, I want long life maintence free that will give equal or better reserve and amps as the T105 at a price not much or any higher than the T105, which I can buy anywhere from $68.00in Fla to $160.00 or so in Az. If I can get 4 maintenance free 6 volts that will fit in the confines dictated by the T105 for $180.00 each or less I will be a happy camper.
Surely in these forums is someone with a connection or information on where to find these??? I'll dance at their next wedding if they will provide some information or sources.

I really do not understand what folks like you are doing to have to add water every three weeks or have so much corrosion on the terminals.

Adding water ever three weeks and not using the batteries much you have an issue with your Converter or charging system period.

Maybe you are just buying used leftover batteries to save a couple of nickels?

I check my Sam's GC2s ONCE A YEAR and when they are new only have to add less than 10 oz across both batteries. As my first set aged to 10 yrs old they took 20oz-30 oz of water across all cells. I replaced them even though they seemed to have considerable capacity, I depend on them to power my Home fridge conversion.

Corrosion on the terminals?

Yeah, you ARE way over charging AND you most likely bought BUM batteries with BAD TERMINAL SEALS!

Had that happen on a lawn and garden tractor battery once, could not keep those terminals clean since the seal was compromised on the terminals and the acid CREEPS right up the terminals.

The terminals on my first set of GC2s NEVER, EVER needed to be cleaned, pulled them off just once just to check and they were so clean they did not need freshened up.

If you have a stock converter, you will do better by replacing it with a different (better) brand..

For the record, I am using a PD9160 with external Charge Wizard, trailer is hooked up to shore power 24/7 when not camping and only get to camp about 2 weeks a year..

Throwing a bunch of money into insanely expensive batteries to fix your problem is just silly and most likely will result in considerable disappointment when you kill your insanely expensive batteries before their time.. It isn't like you can add water to any Lithium based batteries and when they quit, well lets say they just quit with zero warning.
