The battery would have to be sitting in water deep enough that it contacted the battery posts - the connections themselves. Batteries don't short out by just sitting in water. That's a fact.Earlier this year my aux battery died completely and the JT would not jump start at all because the aux battery was totally dead. Granted it had been sitting for a month because I could not drive due to surgery. But it should have charged up with a charger or at least be jumped. I had to have it towed to the service department.
End result - battery was dead due to bad engineering design. There is a water drain hole in the windshield wiper cowling that in the end drains into the battery box. At the bottom of the box is a drain hole. The drain hole got plugged when we had a snow storm and some debris fell in there causing the water to pool. The aux battery was sitting in this pool of water and it shorted out. Both batteries were replaced under warranty. And apparently due to the chaotic electronics while trying to get the vehicle started the radio lost the id info for sirius and gps. Had to get a new one put in - first replacement had an issue recognizing the antennas. Second replacement worked fine.
Who the heck designs the drainage path to go through the battery holder? An idiot engineer. Same type of engineer that designs a furnace such that you have to reach through the furnace through a 3 inch slot to remove and replace the air filters. When we had it replaced the technician cut a access door into the filter compartment so we could easily replace them. Engineer vs. a technician that has to service the furnace. Technician wins.
If the battery is filthy - say conductive dirt, salt, acids, etc. make a path between the posts then it will drain over time and be dead, but it's not a short. It's a slow discharge process.
So unless that water was inches deep to the posts - that's not it.
There's no path through the water for discharge.
Sorry - water in the tray did not ruin the battery.
