till it reacts with something....
given that if the corrosion happens in just the right way, with just the right materials available, that explosion's what you're going to get.....
Completely sealing up a battery box is not a good idea. For all the aforementioned reasons. The batteries need some sort of ventilation.
More to the point (of addressing the OP's noise concern):
You can seal the lid of the box (and internal sides if you have made any holes), and leave the holes in the bottom / external sides for ventilation.
Thanks everyone.
I've sealed _most_ of it.. the main holes and stuff, but I've left the drain in the bottom (which is covered underneath).
Also put dynamat on it and will replace the foam to seal under the hatch.
Should make a big difference :)
