[Elecraft] Battery Power

[Rich Lentz]

>> Shoot, they didn't even allow those things 'indoors' on ships! They were
in their own ventilated locker outside the radio room. 

They do allow them and need them on submarines and these batteries are big
enough you could get in the jar!  Only time they are vented outside is when
performing an "equalizing charge." However, they do ventilate the area to
prevent H2 buildup in pockets. 

Get out your chemistry book and work out the molar equations, for the
average auto/boat deep cycle battery the amount of hydrogen released during
a normal charge is minimal. Very high charge rates (60 120 amp/hr) releases
H2 quicker. But there is still a limited amount. Additionally, there would
be no H2SO4 or H2O left. Even if all of it was used up you are only talking
a few grams (Liters) of Hydrogen and that would be released over several
hours.
