Brent, Some other disaster processes take place that you didn’t
note. With salt water, very poisonous chlorine gas will form (which will
also result in hydrochloric acid formation that burns skin and eyes exposed in
the air, the chlorine will ruin your lungs quickly). Additionally sulfuric
acid will leak out of the batteries which will burn your skin in the water.
A final threat is that when shorted out by the salt water with larger batteries
you can have an explosion due to the rapid dissipation of power. These
have all been documented in previous submarine disasters. It is obvious that your test was not realistic since your
battery still works. Salt water (35 ppm chlorides) leaking into a battery
will quickly ruin the battery. Therefore with your battery still functional,
this indicates that salt water did not intrude. R/Jay From:

Hartwig Last
year I did a test to submerge a small basic lead acid battery in fresh, and
then saltwater to better understand what I was up against if the interior of a
sub flooded with exposed unsealed DC batteries in it. I discovered that
unless I directly touch the poles I'm not likely to get shocked in fresh or
saltwater, but that the battery will split water into H and O2. So you need to
get out of the sub quickly for that reason as well as you don't want nitrogen
to build up in your blood if your going to do a fast accent. Regards, |
