This issue was with one of their large 4V flooded batteries. Our customers accidentally tried to lift the battery by its cover edges and it popped off--luckily, it was a dry back-up battery! Surrette told us not to worry and to pop it back on and seal around the terminals and the bottom of the cover with the RTV.
So no not an AGM, but I figure it is the same basic electrolyte chemistry-no?

Surrette AGM's look to be made by Fullriver which we sell so I'd like to know your experience or any issues with them.

It appears that terminal corrosion starts just under the case covering the terminal connection inside the battery. Not much you can do. The attached picture shows an example of the case splitting open on a GPL-8DL due to this type of failure. The battery is 9 years old and still has 70% capacity.
