Just to back up what hellosailor relayed. Most commercial tanks carrying either acid or high alkalinity liquids are epoxy coated. Obviously the specific epoxy used is the issue.

Thanks everyone for the advice. The wood doesnt seem to be damaged, just was wet and the paint disolved. i have already given it a bicarb bath and will repeat it before i am finished. I think i caught it in time. The system i am dealing with is a battery bank of 6 volt batteries with a solar pannel and wind generator. there is a regulator and has a led light on it which is lit (i assume this means it is working) How would i check the regulator to see if it is working properly. If anything i would think this is the cause of the overcharge. I have inspected the batteries and there is no crack or leak.
I like the neoprine idea. Seems like an easy fix. My question now is "is neoprine really acid proof?" just confirming because i was unaware of this.

verify voltage output controlled by regulator to determine if it is adjusted properly.

Neoprene is resistant to battery acid.

Battery acid is sulfuric acid. According to what I've seen neoprene is only resistant to sulfuric for short periods of time, the Canadians use 4 hours and some US sites cite 8 hours. Neoprene is always listed as resistant, not proof, against inorganic acids. Since a hidden leak in the battery compartment will most likely no be noticed for days at best, neoprene is not a good solution.

Egad, Canadian OSHA. This doesn't sound hopeful.
How about removing the batteries to a place where you can use battery boxes?

this link is for surfuric acid. Although battery fluid in a wet call contains surfuric acid, it is diluted sufficiently so as to be much less corrosive to neoprene, or anything else for that matter, than concentrated acid.

You are correct, battery acid has a specific gravity of 1.25 (pure sulfuric acid is 1.8), and is about a 20% solution. I checked one university site that had 8 hours for neoprene gloves with a 25% solution. I think I'd rather choose something else for the battery compartment.

moving them to another compartment will be a costly task. Not an option. basically just wanted to acid proof the compartment with epoxie or paint or a material

For the proper epoxy, get out of the marine field and call up a supplier of industrial coatings.
