Battery Vents, Required If They Are In The Engine Bay? Or Only In Boot?

I have a question about battery vents, I realise that proper sealed ones do not require them but the cheaper type do. Now is this only if they are located in the boot in a box? Or is it if they are located in the engine bay as well? If so, where must the breather hose be attached to, just venting to atmosphere?

From personal experience be wary of batteries that are sealed but have vents.

If they have vents run a hose from the vents down to a point below your car so the acid will not spray on your car and stuff it up.

I had one installed in the engine bay without the hose and it sprayed acid everywhere when you start to throw the car around a bit. The problem then is that because the battery was sealed I could not put any water back into it to top it up and had to throw it away because it was low on acid and stuffed.

I now only use fully sealed batteries on the boot or if it is in the engine bay one with caps so you can top it up.

      yeah I've never understood that either.... And to answer an earlier question, I write the date on open bottles and throw them if more than 12 months old (which they almost always are, because I don't need to bleed them unless I'm changing lines/calipers etc in between)

      Nah, the one that hit the boot was a big steel locker, around 6 foot height, 4 foot wide and 2 foot deep, empty it weighs about 15kg and had about that amount of stuff in it The photo didn't give a good representation of the actual damage, the large ding on the passenger side was about a inch deep, the one on the driver was about 1/2 inch deep, right on the curve, where the inner boot frame doesn't let you get behind it with a dolly Basically the same issue with getting behind the damage on the centre of the boot We could have filled it all with bog, but my OCD would be triggered every time I looked at it, knowing what hides beneath  As for the locker, I did get the shits with it and put it in the scap metal bin, but, I pulled it out and it is now sitting in the garage at home full of car servicing stuff, cleaning gear and random tools, it's going to pay for it's indiscretions

      Whilst I typically don't cheap out on things, if I can save some money, like $1000, on a clean straight panel, that gives me $1000 to spend on other stuff, basically free money really 🤔 🤣

      Is the toolbox that damaged the boot seal the same item that fell on the car during the storm a while back?

      Who are you to deny yourself? I’ve said this many times to myself and apart from getting what I really want, I go quiet for a while whilst working out what I just did to my savings and how will I afford what it cost, then, next payday…
