Your point is well taken and speaks to the point that batteries should
only be installed in approved locations. There must be venting.

I suspect that the manufacturer of the charger is concerned about two
potential issues.... the first is the (natural and expected) out
gassing of hydrogen... the second might be an improperly grounded
circuit associated with the charger that could cause damage (read that
lawsuit) to adjoining floating boats from galvanic erosion.

My three batteries have good ventilation. Two are under the console
which has a 16" square opening and the aft battery also sits beside a
similar sized opening.
