How does a “sealed ” battery vent itself ? I had an AGM battery in a small area in our Eureka TC cabin and never noticed anything whatsoever coming from anywhere on the battery. We lived with this set up for about a year.
This battery was charged by the converter, by the truck’s alternator and occasionally by our Honda EU2000i.
