I was just reading a few pages of this extensive topic. I came across your mentioning of the infinitum and it piqued my curiosity. I saw where you said it works great on a single battery but would take much longer on a battery bank of 200 or 400 AH. I noticed that they sell the desulfators in multiples and wondered whether they did so because it was necessary to have one for each battery in the bank. For my edification, what size battery bank do you have?...how many of these infinitum gizmos do you have hooked up?....do you need one for each individual battery?....do they work on 6VDC as well as 12VDC batteries?
You sound as though you are satisfied with the product.
