Well, I picked up the charger this afternoon and not sure if its going to do me any good. I don't think it's robust enough to PROPERLY charge and desulfate my Interstate GC2-ECC-UTL 225ah 6 volt deep cycle batteries. A big mistake purchasing them with out THROUGHLY resurching charging specs.
The Xantrex Freedom 458 WILL NOT fully charge them. The bulk and absorb voltages are too low.
Im running out of options and more important, money!
The charge specs I programmed into my charge controller was properly charging the house batteries but i have been under trees for the last two years!
I have known for the last three years that the Xantrex was not fully charging them but did not find a solution. I need to desulfate them or they will be toast!
Here's an interesting post a few years old worth reading to give you an idea where I stand
