I appreciate the many comments and suggestions but back to my original question....
1. we are travelling through the U.S. so I can buy them here on our travels.
2. I want to try AGM's because my battery tray does not slide out enough to check the back two batteries. I took the batteries out this summer, cleaned and lubricated everything but the slide still does not move enough to access all.
3. I am pretty good about maintenance but still keep boiling off the water in the rear batteries and am tired of fighting to add water and have ruined several sets of clothes with splashing acid,
4. I am willing to try the Sam's Club Duracells but can find no tech info on them anywhere. I stopped in at Sam's in Springfield yesterday and they were no help.
5. I am willing to order them online through Sam's and pick them up as we travel.
Does anyone have the tech specs on the Duracell AGM's?
