RE: [PSUBS-MAILIST] Battery Safety Issues

Good Evening Jay,
 
What about the sealed AGM batteries, like the deep cycle Blue Top Optima batteries, will they loose there seal and break open if they are submerged in water?  I wouldn't think they would, but I haven't tipped over my fishing boat to find out,  YET. ; )'  In regards to normal non sealed batteries I hadn't heard of there pressure fitted snap lids being force off by a reaction to them being submerged. Is that what your saying or are you just talking about the small amounts of battery acid that leaks out normally getting into the water?

Regards,
Brent Hartwig

Brent,

With the batteries located inside the pressure hull without a proper sealed container, I would be more worried about the sulfuric acid and chlorine gas that will become an issue with flooding.  With a rapid discharge of the batteries (or during charging), explosive hydrogen gas can also be an issue.  A prudently designed, well tested, and properly maintained submersible shouldn’t be getting into the flooded situation anyway J.

 

Sealed breaker (fuses for high amp DC) boxes and conduit will minimize stray electrical issues in a flooding situation.

If you have one or more batteries in the pressure hull with you, and not in a sealed off area, how do you keep from being electrocuted, if the inner hull floods? Will not the batteries short out in fresh water, and even more so in saltwater? I would love to be enlightened. ; )'   Perhaps someone else wants and/or needs to know as well.
 
Even if the batteries are in pods, or another hull section, will not the breaker box cause and other wire cause your trouble?

Regards,
Brent Hartwig
