But it does not mention Temperature Compensation, so how does it do what they claim?

Their literature says it doesn't overcharge (.. implying from too high float voltage at high temps) and that it removes sulfate from the battery plates (.. implying the sulfate formed by undercharging from too low float voltage at low temps). So it appears that they have all of the negative bases covered from not being temperature compensated. Regarding the low temp coverage - you just have to believe in "high-frequency pulses" being able to control sulfation.

I've had one connected to my RV's same main engine starting battery thousands of hours for 6-7 years and so far the V10 turns over fast every time. I add 1/16 to 1/8 inch of distilled water to each of it's cells whenever I think of it - maybe every two years or longer. Sure wish I could afford an AGM engine starting battery so I wouldn't have to use distilled water anywhere in the RV except for maybe a steam iron.

Adding an 1/8" of water every two years is too frequent? What, are you retired? Maybe pop the hood every two years too, to see if any rats or mice have made a nest in there too?

I kind of like peaking around at my radiator hoses and such every now and then to check their general condition. My wallet will wince more for the extra $$$ to replace the AGM's in my Passat and two Touaregs... They don't last very long in the heat underneath the engine compartment.

Yes, batteries are commodities, but I feel a lot better when they go more than 6 or 7 years before needing to be R&R'd
