Anyone pull their battery and notice water under it?

I installed a wire harness for accessory lamps last night and found water under the battery on the tray.

I know that after either rain or washing the car that there is some water on top of the battery.

I have an issue of water draining off the RH cowl, and over the strut tower and draining onto the frame below.

I know that the inner fender edges act as a gutter of sorts, but in this case either side is allowing water to drain off into the engine compartment.

Anyone have this problem and/or solution to fix?

Thanks.

I've also noticed water under my battery tray, not so much driving in the rain but especially after washing. (I guess spraying the front with the nozzel gets more water in there.)

In the fall and winter when it's dry it's not a problem, but in the summer my car will actually stink up the garage - I had to remove the battery and the tray and pour out the water.

I thought about a strategicly placed drain hole, but it doesn't happen often enough that I've actually done it. (keeping my garage dry with the de-humidifier helps, along with leaving it outside to dry before putting it away)

I thought I was the only one.

I thought I was the only one as well. No joke. I don't know y water builds up right there! Does anyone have an answer? Please let us know.

The idea of the tray is to contain any minor acid leak so it doesn't get to the car and eat through the paint and/or the body. So yes, if rain or water gets in there it will stay. I suppose the best answer would be some 1/4" or so plastic bumps to raise the battery a little so any water could get air flow and evaporate.

I think that I found the problem.

The top inner fold of the fender (only seen when the hood is open) acts as a gutter. Next to the battery, and on the same horizontal plane on the other fender, is what appears to be a drain hole.

There is also a hole underneath in the frame. By rights the hole in the fender edge and the frame align and any water would drain through.

In my case however the fender edge does not contact this top surface of the frame and therefore water has the opportunity to enter the engine compartment over the frame.

My solution was to take some 3m butyl-caulking and plug each hole on either fender. You could use plumber's putty as well.

Since it has been raining here for the past day or so, I will check later this evening to see if I am right.
