So the good news is that they did replace the battery under warranty. However, the description provided in the paper work has me stumped.

They said the there was a "battery failure" due to an "aged battery". This battery was just put in ~20 months ago, so what would cause it to age? Also, it was noted that the "aged" battery was originally "replaced but not registered." Could not registering the battery have caused the premature aging? If so, I guess that would be why they were willing to replace under warranty (as the last replacement was done at a different dealer).

And finally it says the tech "registered on ISID" and performed a battery "retrofit in ISTA-P". Huh? What does that mean?
