I have a 100ah renogy agm sealed battery. I have it in a small room in my house connected to the other necessary solar equipment.I have been reading that these batteries will emit hydrogen sulfide and/or hydrogen. My concern is about how much do these batteries really emit and how well should I be venting the room.Theres fans all around my house blowing anyway so I'm hoping the gas just mixes into the air and everything is fine.There is conflicting information on gas emmisions from these batteries.So, once and for all.Do they give off hydrogen sulfide or not? Also hydrogen sulfide is heavier than air so what's the concern with that?

Valve regulated lead acid batteries only vent when over charged.
They are sealed to allow for the recombination of the H and O at some pressure. The valve vents anytime the pressure is too great.

It's always a good idea to vent the room when batteries are concerned. Hydrogen is an explosive gas and electronics do, at times, produce sparks.
Having said that, my deep cycle lead acid batteries are located in the same room I'm typing this reply from. The room is roughly 18 x 10 x 8. My Renogy Solar installation has been in service for just over 4 years now. Lots of electronics in here, too. And I haven't asphyxiated or gone boom yet.
I suspect you'll be just fine.

Yes sir, My solar system and batteries are vented and in the room where I sleep and have been for over 1 and a 1/2 years.... |

When it comes to having an AGM battery installation, we readily recommend any kind of aired space that's bigger than a battery box, this should be fine. The AGM battery chemistry should actually be okay with ventilation and users don't have to worry about any potentially toxic fumes.

So, if one were to put 2 100ah AGM batteries in the interior of a truck camper to store solar energy in, what would be the needed amount of ventilation in there? Or, where can I get an external battery cage of some sort to hold each of the batteries fastened against the underside of the Truck Camper frame in front of where the wheel wells of the truck would be? I need to keep them attached to the camper and not the truck. They would be up above the wheel wells in addition to being in front of the wheel wells to allow the camper to be loaded on and off.
Thanks!

hi, ive turned my school bus into a rv (camp on wheels) and i have a mid size fridge and freezer 6 amps each off the top of someones head how many 250 amp hr batteries do i need to last a week without sun like in the winter i have a aims 4000 pure sine inverter and whats the best battery for the buck if they last pretty good i dont need the best going id rather go big to start with im thinking 12 of them @12 v 250ah id rather be a hair to big than to small so my discharge will be smaller so i can use cheaper batts to start does this sound reasonable?

inverters are DC appliances, seems I;ve read here or there that DC sucks! always a good laugh.

It has nothing to do with inverters it's the DC load side of a CC.....But when you only have solar lights on the walkway to your house I guess DC is just fine ain't that right bird? |

So far so good.Battery has been charging heavily every day and I can't seem to notice any problem.

I have two Renogy Deep-Cycle AGM6-260 (6V 260 Ah/20Hr) batteries connected in series for my RV 12V system. In the Renogy battery specification of 'Charge Voltage 25-DegC' for 'Cycle Use' applications I see a note "max charge current: 27A". Is this actually the maximum charge current (in constant current Bulk Charge Stage) which can safely be pumped into these [series-connected] batteries? I thought Deep-Cycle AGM batteries tolerated high charging current rather well - yes? If so, then 27A seems well below another manufacturer's recommended AGM charge current of at least 52A (battery capacity 260Ah * 0.2) for repetitive deep cycling applications. Also, assuming that RV usage results in approx 50% DOD each day, it seems that daily charging at the low 27A or less (due to solar panels flat on roof and variable sun irradiation levels) may tend to risk an undercharge problem whereby the battery’s state of charge may gradually “walk down” as it is cycled over successive partially overcast days. If AGMs are subjected long term to under-charged cycling, wouldn't this eventually have negative affect on battery life? Am I missing something? |

Forget about Battery state of change SOC it means nothing and it shouldn't even be there....
Are your batteries going to float? What is your voltage in the morning and what is it at sun down?

So with all this talk about AGM Batteries emitting dangerous or explosive gasses when the manufacturer of AGM Batteries (including Renogy) says that they can be mounted in any direction. Am I missing something? I was under the impression that AGM Batteries are completly sealed.
