It is possible you have an internal leak in the battery. There is a drain plug on it that will tell all when pulled. Pain to get to, it is on the bottom, the protective panel will have to come off to get to it.

Updated the first post but the news is not good! The car is actually missing a clamp on one of the coolant lines. Astounding.

Actually, that news is not so bad, assuming no other damage.
