Water in Battery Box?

[MrT]

I typically remove the battery from my RV when I park it in a storage lot, just to limit the possibility of it walking off. On the new RV, I've noticed that it seems to collect perhaps 1/4" of water in the bottom, perhaps just enough to fill the recesses.

Any reason why I shouldn't drill a few drain holes?

It's normal.
In a boat or enclosed space you want it to hold water/acid leaks.
If it's sitting outside on the tongue it needs some drain holes.
I drilled mine!!
You should too.

I also drilled some holes.

Mine filled with water on the trip home from Elkhart. First mod half a dozen 5/16 holes in the bat box.

Drilled holes in mine.

Drilling holes in the bottom also helps any vapors to escape through the top. Be careful not to drill the holes too large. If a bee or wasp can get in they'll make a nice nest in there and you won't want to find that when you take off the top to check the batteries.
