But i can tell you this , the temperature of the battery atleast in my case is mostly at room temperature or warm but still less then human body temperature.
Sure and that's the key. At such a low temperature there won't even be steam (water vapour) coming out and that is even when it is being charged. You want the battery to be cool as you get the most life out of it, if it gets warmer then its life gets considerably shortened. From
here
The optimum operating temperature for a VRLA battery is 25°C (77°F). As a rule of thumb, every 8°C (15°F) rise in temperature will cut the battery life in half. VRLA that would last for 10 years at 25°C would only be good for 5 years if operated at 33°C (95°F). The same battery would endure a little more than one year at a temperature of 42°C (107°F).
Even if water is less, the battery won't overheat, it will just get ruined slowly as deposits slowly build up on the plates reducing plate surface area to react and subsequently the battery's capacity will drop.
If the vents get blocked for some reason, then the O2 & H2 pressure builds up but temperature will still stay the same until it blows. This is the only risk i can see, make sure those vents are clear.
Otherwise the battery is not like a pressure cooker with high temperature & pressure

You have to coat the two terminals with vaciline which is a 100% pure petroleum jelly,this prevents any kind of salt formation.A thick layer of this lasts about a year haven't seen any salt formation and the jelly still remains.
Noted but i'm curious why the deposit builds up in the first place. Meaning it should normally happen on the plates
inside the battery rather than on the exterior terminal.

Long time ago I had sawed open a sealed lead acid battery just for curiosity the lead used used was powered lead which was fixed into some sort of mesh, mind you though it was powdered it was damn hard to break it up literally I had to hammer it down for a few times to break it.
We're talking about fumes with flooded batteries here not sealed ones.
We maintain there are no 'lead fumes' coming out of flooded batteries or tubulars.

As for fumes from tubular batteries I havent seen them using tubulars since 1.5 years with average use of 9 hours /day no incidents and no problems
You get oxygen & hydrogen as natural byproducts of the process. Somehow those gases are being turned into 'lead fumes' by advocates of sealed batteries and painted as a health risk. I have to say that i cannot see how this can occur under normal operating conditions. There seems to be no basis whatsoever to the claim of 'lead fumes' emanating from tubular batteries. And that holds for any tubular battery, whether its no-name back of the alley brand to branded ones, because the chemistry does not support it.
As i google around the only ppl making this claim of 'lead fumes' is Su-Kam. Its misleading and false info
