We address this 'storage' issue in various threads on this forum. Anything over about three weeks and the 12v battery should be either disconnected or attached to a smart 'float' charger (not old-fashioned 'trickle' charger). If outside, a very small solar panel with regulator also works great. With OEM 12v batteries now with four-year+ lives (and thus diminished capacity), I would slap on a 12v float charger even if I left the car for a week.

Excellent data point.

That's sort of what I figured and if it was me I simply wouldn't worry about it as the 'failure' cause has been identified.
