I too saw that these were AGMS. The only time excess H venting happens is with
severe over voltage for a period of time. How often will this happen? Have any
battery wrenches experienced high volume venting of AGM’s?
Our experience: There is no NEC requirements for mobile installations. We have

Hello Wrenches,
A client wants to use a passive battery venting method with a heat
exchanger to the outside for his bank of Full River AGM batteries.
Below is a link to one site that recommends this method. Has anyone
used this method?
I have used hi low vents on the same exterior wall with no issues and we
have used the firewall through wall terminals there we a pvc box and
connect the pipe to that. Every part has a price and it all adds up

Hello
That's an interesting idea, but all the failed designs they illustrate
don't show the way we usually do it. We don't even bother with an
inlet, as most battery boxes have enough gap around the door to provide
intake air, then the exhaust comes off the top with several feet of rise
to prevent
We do what we can to seal the enclosure so if or when a battery fails and
really gasses off the two vents on the same wall regardless of wind
direction will vent the gas. If it is not sealed then the gas can travel
through out the area this is not advised.

I do agree steel and copper/brass is to expensive for the possible return.

I've seen some cases of very well sealed and insulated enclosures
allowing batteries to over heat, and also build up a lot of acid damaged
connections.
