Question about the original thread

I am not sure about the etiquette but I just have a question about the original issue of housing batteries in the trailer. I am taking my trailer (1975 Ventura) down to the framing and rebuilding it. I am removing the fridge and was thinking of using the bottom of that cavity to house the batteries with a shelf above. There is a large vent on the exterior that I was going to change to a hatch (or modify the metal vent) so that I could access the space from outside to attach stand alone solar panels as needed. If I sealed the box on the inside would this be a reasonable approach?

As long as you vent it to the outside.

hydrogen....

hydrogen is FOURTEEN times lighter than air so getting rid of it is pretty simple / easy....as long as the vent (exhaust) is higher than any other space of the "container" the gas will be gone in short order....

whichever way you decide to go...keep in mind that for a problem (explosion) to occur there has to have been a spark produced by something... like a loose wire near the battery...guarding against that is as important (or more IMO) as venting...

good luck and don't forget to post pics...."no pics, didn't happen"...LOL

Do True AGM Batteries need venting?

No!
The information that I read from the major manufacturers say that they can be placed in any direction, even upside down, and require no venting.
I just replaced 2 size 27 True AGM batteries that spent their 1st 8 years as backups for a telephone PBX system then I used them for 6 years in my Bigfoot 17. They both failed within the same year - good quality control. When removed from service they were completely sealed and dry. That being said, I use a Progressive Dynamics Intellipower(?) PD-9060 Converter and monitor their performance constantly with a Xantrex Link 20 dual battery monitor system.
Now, is it a good idea to vent them?
Probably, since many systems can fail and either overcharge them or over discharge them, or they fracture from travel, or other reasons. Certainly I would suggest a plastic battery box and constant visual inspections.
This is my information for my purposes only, you can do what you want, but I keep one on the tongue and the other on a non-vented battery box, well strapped down, inside under my passenger front seat.
Ka-Boom - I hope not.

Thanks

I usually go the cautious route so will make sure that the batteries are located where I can monitor them and where they can be vented.
I am still in the planning/design stage and reading ahead on the forums is really helping me see possible pitfalls but, best of all, possible solutions.
For sure I will have pictures but they will be a while, I am going to enjoy the process and not rush.

Any battery in the trailer needs to be put into a special box that vents to the outside.
I talked to the LifeLine tech department recently out gassing of AGMs when housed inside the trailer. Not an issue, its standard practice he said. I asked about their published statement that says can not be in an enclosed area. He recognized that is confusing. What they meant was it can not be sealed in a container. In the trailer cabin, with potential gassing being so slight it would dissipate without a problem, that's IF it ever happened.

I will be installing three banks of AGM in my ordered Escape and currently have a Gel battery inside the 05 Scamp 13 I just put up for sale. No maintenance ever, terminals are clean and look like when it came out of the box. Speaking of which, they can be shipped UPS because they are safe. Cost is higher but you will get it back as they last a lot longer, in the end they are cheaper.

For anyone considering even AGM batteries unvented in your trailer you might read this thread.. True, it shouldn't happen, but...

Good, I was about to post the same link. A very long thread but basically the AGM batteries installed by Parkliner vented acid. Parkliner has since moved the batteries onto the tongue.

Years ago I noticed a spark anytime I connected the wires to my battery. Like almost everything electronic these days many of the devices in our trailers are never really off. I traced the spark I was seeing to the hardwired propane detector. To minimize any explosion risk I went to an AGM battery and added an inline fuse away from the battery that I use as a disconnect. Also, I use a two state charger to charge my battery when home instead of the four state charger that came with the trailer. It's slower but at home I'm in no hurry. Raz

IMHO, having a master battery disconnect switch (or breaker) is:

1. A major safety feature. In case of any problems like a short that cannot immediately be isolated, suspicious electric arcing smells, or even an actually fire, the battery can be shutoff almost instantly.
and
2. A major convenience. When the master switch is off you know you can disconnect from the battery terminals with no chance of sparking. You can also disconnect those phantom loads like a hardwired propane detector and stop your battery from discharging.

Pulling a fuse works too, just not quite was well. But kudos to anyone who has made a battery disconnect improvement.

I was going to add a switch but after reading review after review of failed switches on Amazon I decided to go with the inline fuse. Besides I like having the fuse close enough to the battery to protect against the lead in wires shorting.

Hummm...... the fine print from all the AGM battery manufactures I have read say they recommend they be vented. We even had one of the manufactures reps come on here when this topic came up previously stating they recommend they be vented.

You know this better than I do, but for the rest of the audience..

The "master battery fuse" should be included in all cases, and as close to the battery terminal as possible.

Scamp installed my master battery fuse a full 10 inches from the battery terminal.. thats ten inches of wire that could short out and burn or spark.

I prefer (and use) the Blue Sea Systems terminal fuse because it adds the maximum protection against causing a short at the terminals (such as might occur if someone were careless with tools), as well as protection further down the line. The down side is that you need a wrench to remove the fuse, and it is more expensive.

I used one of these with a 6" pigtail to the positive terminal.

or this...

...I'm not too worried about that 3 inches of wire (#6), in the corner, between the fuse and the battery box...a couple of inches of wire was exposed on each side of the fuse holder and that was soldered to the large wire...then thouroughly wrappped
