I know a lead battery gasses when being charged. Does it also gas when in use ? What about when it is not in use? I am starting the battery compartment soon and am gathering info on natural venting or mechanically venting. I know natural venting is good. AGM batteries would make life simplier, but seam a little pricey. Vern (in RI) |

Before kissing off AGM , you should see if their advantages fit your needs.
AGM will cycle deeper , and recharge faster , and live longer between charges, for a load of cash.
So if your space & charge time limited and have a huge recharge setup , or the coach sits for months , unused , they could make sense.
If this is a need , they should be looked at by price per USEABLE amp.
A special lower charge voltage is needed, stock wont work.

Batteries will gas during heavy charge or during heavy discharge.
Natural venting is preferable since it is always working. Do not skimp on venting. A battery compartment explosion can ruin your whole day.

On our Eagle, the guy who converted the bus built a battery box for the 8D house battery with a single hole that goes thru the bay floor. The hole is about 2-3" in diameter. Is that sufficient venting? He used the bus for 5 years like this, but I don't want to have a bad day... |

My opinion is no. Where does the fresh air come in to expel the gas out the bottom opening? I do not see how there could be any circulation.

Gassing while driving…yes indeed…whenever alternator is running...it only charge whenever electrical battery (12v or 24v) power needed. It always charging until it reaches full state of charge after starting engine.
About battery compartment; Hydrogen gas rise. Should have well (both...highest side or above opening to exhaust & bottom opening for intake) vented area. If not it would be like an explosion waiting to happen while charging on road with lid close.
Hydrogen gas from battery is very instantaneous explosive gas. Faster than gasoline vapor.
Example during High school class in mid 50’s outdoor demo was a paper (foam unheard of) cup with 3/16’ tygon tubing inserted into cup w/sheet of paper to seal, that connected to on top to battery’s cap (drilled for tube). Heavy charge battery w/charger for about 5 minute. Remove tube from cup & keep paper seal on top of cup. Have two volunteers….one to remover paper while other throws in a lighted match. Result of explosion was so fast even with wide open top, it split open cup’s wall flat to pavement all around. Now that….I will never take Hydrogen gas lightly since 1956.
To compare to gasoline vapor gas explosion in cup would only puff with no or light physical damage except it may burn afterward.
Wish you well on project.
FWIW

So far, FF does point out an interesting way to look at this situation, price per usable amp (I'll have to figure it out when I have some time), AND venting not criticle that way. Plus' and minus' here also. With money being the minus. Jerry, I believe is correct, with the volitility ( did I spell that right?) of the gasses. That is why I am seeking some advice here. And Brent's situation would make me a little unconfortable. More input is great, keep those cards and letters coming in, folks! Thanx all, Vern (in RI) |

" remember the Challenger disaster? This was hydrogen doing it's thing. "
We have a different memory , I believe it was BURORATS who didnt give a damn,but had a sked, having a vehicle with a known problem being flown "outside the Envelope" was the source of BOOM,.
It was known from two previous launches the set of O rings sometimes stopped sealing in cold temps, the publicity of reskeduling sent these poor folks off to their Death , with a 20deg below past temp launch.
The Shuttle sysem was supposed to do a launch every week with a 3 week turn on each shuttle.
Ha Ha ,Now its once every few years , with a batch of Eurowinps screaming that we didn't launch their national pride $cience experiment packages to the space platform.
Probably the US tax suckers will get to buy the billion dollar packages , after the last shuttle ride , leaves them stranded .

Vern, you asked if you had spelled volitility correct, and no you had not. Volatility is correct.
Several weeks ago I posted the address of the Google tool bar and suggested that a person could use it to correct spelling errors easily because there is a spell check included. Just for a check, it actually found FOUR misspelled words in your message.

JTNCG is sure a non-conformable guy!
IIRC, Richard's original post was offered as an helpful suggestion, not a denigration for poor spelling.
Some potential posters refuse to comment because they're sensitive to such criticism, a "threat" you appear to have reinforced with the "Bahhhhar har har har...", comment.
Richard, had he a sarcastic, conceited personality, would have revealed such long ago.
WYSIWYG, as far as DML, [and JTNCG?] is concerned.
Clear it up for us - that your "Bahhhhar har har har..." was an expression of amusement not sarcastic irony?

A lil' of both, boss.
I think Richard sees the irony of having a Google tool bar
at his fingertips, and posting in such a manner as to have us
feeling unconfortable with his oversight. (heh heh)
Ain't no big deal, Marc. There wasn't any insult intended.
I'm sure Richard knows that.
As far as "new posters"? No-one should feel intimidated
by any other poster on any BBS, regarding a lack of ability
to spell correctly, or lack of being a grammatical guru.
It's the thoughts; the ideas a person has, that's important to
hear and read. At least it's all I care about.

I do not recall ever calling anybody's attention to a misspelled word as far as a put down is concerned.
Personally, I hate to make a post and then later see that I made a spelling error. There are many more on the board who have indicated that they do not like to make a spelling error. It is really no big deal as long as everyone can understand what the person is talking about, but for those of us who dislike seeing a misspelling in our own posts, the spelling check is very handy. And no it does not catch every error.
Richard
P.S. On this message it found five typing errors that I had made. LOL |

Come on guys, I am getting more responses to my poor grammer than the subject. May be that is why I am not getting much response......they just don't understand me. I am feeling very...... I won't spell it....probably wrong anyway. Vern (in RI) |

Vern -
Actually, both FF and Richard answered it right off the bat!
Probably others figure what they'd say would be redundant,
and didn't bother to add their comments.
Vern, don't worry about the way you type it out, you're doing fine.
Sorry to hear about your grandma.

Why not buy a boat bilge vent fan, and wire it so that it kicks on when you start the engine? (Try www.westmarine.com)They are cheap, explosion proof,and will provide worry-free venting. Use flexible plasic tubing to route the fumes overboard. Mine's so quiet I have to put my hand on it to feel for vibration to see if it is running. Cheers...JJ |

Fast Fred, I remember the same things about the responsibility for the Challenger. When I mentioned it, I was only talking about the blast. I thought it would give a good illustration of what hydrogen can do.

I'm also going to look into the boat bilge fan. I bet I can wire it to one of the 12V circuits in the Converter/Charger which is only on when I have shore power or the genset is running. I don't think my house battery gets charged with the alternator.

Cost of Lifeline batteries went so high that I am no longer considering them. there are occasionally some insutrial AGMs that appear on Ebay but usually they are very expensive and large. I am back to looking for a fork lift battery I can fit in my compartment. |
