Battery vent with hose barb retrofit????

I would like to replace the standard vent caps on my 6v deep cycle lead acid batteries with ones that will vent into a hose, yet as far as I can tell they don't exist. Any ideas?

Check with suppliers that deal with solar and wind power. Battery Miser caps might be what you want. They don't connect to a hose though. My batteries are situated such that they vent into the atmosphere. Are you using a battery box of some sort or are your batteries in the passenger compartment of your truck/trailer/living quarters?:coffee:

Well I just made a box that vents outside for use inside the vehicle. It was a pain to construct though, and I don't really trust it to stay air tight, meaning I might have to redo it in the future. It would have been a lot easier to just stick a hose onto the vent like they do on cars that have the battery inside the passenger compartment.

In the future I was thinking about mounting batteries to the frame, but I was trying to come up with a way to heat them in the winter. The easiest way would be an air duct connnecting my heated interior to the battery box. However then I have to be able to vent the batteries via a hose or something.

Anyway it seems like one of the main reasons people go with agm batteries is the outgassing issue with lead acid, a simple vent cap barb would solve that, though I can't seem to find one sold. They have water maintenance caps with barbs but they do not vent through the barb as far as I can tell, though I have never seen them in real life.

They do have those caps with the catalyst in them, but are those effecient enough to allow indoor non vented use?

I dont know what exactly your caps look like or how large etc.
But could it be possible to simply remove the caps, drill,tap & screw in a threaded plastic tubing connector ?

Your probably right, that might be the easiest solution. I am really surprised that they don't already exist. It is one of the major reasons people spend more money on AGMs.
