I would love for you to qualify that statement?
I just replaced two working Winnebago OEM FLA batteries with 2 new V Tank Pure AGM Solar batteries; in my opinion it is one of the best things I have done since buying the RV
1. There was nothing wrong with my FLA, but I was tired of the corrosion in my new coach and the cleaning involved.
2. I do not wish to have to add water. Not saying I can't, nor that I don't know how, or if there are easy ways to do; I am saying I don't want to add water and check levels PERIOD.
3. I didn't even have to go to a 6v GC; as I got two Group 31 with 125 AH each for total of 250 AHs.
4. I have yet to get the new batteries under 12.5v during my normal routine; with the FLA my genset would kick on at least 3 times a day during my normal routine set at 12.2 vdc
5. Since it is Pure AGM it has triple the cycles and rated to last 8 - 10 years
6. I have not even had to open my Battery compartment since I took my last pictures of the new batteries
7. No dangers of acid around
8. Maintenance free
9. I posted on ebay and still could not give away the two OEM stock batteries!!!! I eventually just dropped them off at nearby Auto Service center.
1. I paid about $250 more than the FLA
2. About 60 pounds heavier
3. That it took me about a year to learn that I should I bought these AGM batteries on Day 1
None of the above disadvantages constitute a limitations
on my part.
