That's great Jerry... but you miss the point of the question of the original
post... in which the guy was asking about hot air entering his van through
the battery box... I responded that it should be sealed and they he may be
breathing the toxic emissions from a charging battery if it is not sealed.

Yes, good point... I have brought this up many times to those who choose
auxiliary batteries that are not sealed.... one reason I installed and
recommend the Optima which is a sealed battery.
