I have owned many vehicles over the years and never even heard of batteries living that long, especially ones that have been through what these have. I can't count the number of times that it jumped my trailer's gen, a trailer killed the truck, a quad was used to get the truck charged enough to start, etc etc. The truck was still starting fine, but I immediately put two new interstates in it!!!

Dosen't suprise me, my neighbor always gets 10+ years out of his batteries in his vehicles.
The first thing he does is add a solar trickle charger, then is fanatical about maintenance, keeping them topped up and cleaning the cables.
He's made me rethink my replace them at 5 years, needed or not. The only batteries I have had a problem with have been AGM, had 2 of them crap out prematurely. First one was a free replacement, the second made it to 2 1/2 years. Never bought another one.
You were lucky to get 10 years out of yours, if they were treated as you describe. The biggest killer is letting a battery run down, then jump themand charge with the alternator.
