Battery box question
|
Tue, 18 January 2005 08:49

Hello, i know this has been discussed before but I am still a bit confused...
My battery is already in the back of my car and its the style that has tubes to vent it outside the car. So I haven't really worried about having it in a box.
But I want to do things right now and fit it in a box.
The things I am not sure on mainly are concerned with mounting the box to the floor, and also having the battery mounted inside the box.
To start with my battery is around 240mm long, 175mm wide and 175mm height.
There is a battery box which is 280mm long x 180mm wide and 210mm high.
So the battery would be quite snug in there, but does that leave enough room for some mounting device?
Like do I need to fit a bracket over the top of the battery? If so I guess the box needs to be quite a bit wider than the battery so the above box wouldn't work.
Or can you have some material strap inside the box which would take bugger all room?
Anyone have pics of the inside of the box?
Thanks
Joel

I dont have any pictures but the battery doesnt not have to be fixed in the box. If its not a tight fit, just put some rubber down the sides.

So I can just mount the box to the floor, and sit the battery in the box and pack it with rubber or something? No bracing required?
Also, the strap that you see on battery boxes, does that just hold the lid to the box? Or does that also mount to the floor?
Thanks

The strap actually holds the box and lid to the boot floor. Some of the good quality boxes come with two straps which I think is the way to go.
Also you are best off making some kind of brace that is bolted to the floor and the box sits in so that there is no way the box will ever move.

Ahh ok cool that makes more sense.
Would scrutineers at track days etc expect to see the battery somehow bolted down inside the box? Or as long as the box is secure they are happy?

I would have to check on that with my boss for you, but I dont think we have the batterys strapped down in the boxes in the rally cars.
I'll let you know.

as long as the box is secure. for track days, an eng certificate is usually sufficient to allow you on the track.
put in the box, put in metal plate, bolt plate thru box to floor. put in battery & pack with rubber. strap over the lid, which is screwed into boot pan
(that's my plan anyhow)
and dont forget, as well as the battery being vented (like mine is) the box also has to be vented. Yes, the rta is stupid.

Draven, the metal plate you mentioned to put inside the box, would this just be 2 strips down each side or a metal tray that fills the base of the whole box?

Sounds like its all quite easy. I was confused because thought the battery had to be secured inside the box via some mounting system. If this is all correct and just has to sit in there with rubber etc thats easy.
Cool1, if you wouldn't mind asking about those rally ones you do for their requirements.
Thanks all

I'd have to disagree. I remember my mechanic telling me the battery needs to be heaps secure because vibrations can stuff it (first time i heard that so i'm not sure)
anyways my battery is mounted in the boot. I have a bracket underneath the batter which is bolted to the floor. it has two tabs bent perpendicular to the floor with a hole in each end. I got another bracket from the local auto store (everywhere sells em!) that goes over the battery and has two rods with a hook on the end that went through the hole at each end.
I also got a battery that doesn't vent vapours. $130ish from lions batterys - parramatta rd burwood. That way i don't need to stuff around with a hose and it's much safer.
batterys vent hydrogen ->
hydrogen + fuel from surge tank in boot + air + spark from battery = kaAAAAAaaBOOOM!  (according to the engineer)
I don't have a strap for the lid of my box but I keep the lid on anyway just incase the battery explodes.

Umm oookkk. Wel if you know that vibrations can stuff the battery, you would also know that no matter what type of battery you have(sealed or other wise), you still need to have it in a vented box.
No if buts or maybes. This is the requirement in all states of Australia. Again, no if buts or maybes.

i take it you mean bracket 1 to be a battery tray
and
bracket 2 to be a battery clamp.
ie... the usual front setup in a boot box
ps
you will need the box big enough to fit the tray plus
some extra space for the battery clamp rods to hook
through on the sides that they hook on to.
or maybe you could get away with drilling right through
and the rods hook through the box too but i think that is
not the best idea.
well good luck, hope it all works out

*points at shane*
all batteries in boot must be in a sealed, vented to atmo box. I specifically enquired about this when investigating what battery to get, and if an optima/sealed battery would help at all. the answer is no (but I got a sealed one anyhow, as it has uber CCA and amp hours)

Hmm so a few conflicting stories about how the battery should be secured inside the box.
I understand what you are saying Celica John with your mounting method. That basically is how mine is mounted now, but not inside a box. There is a metal bracket over the battery, with 2 rods down each side.
I am not sure how well that will go for me as it seems all the boxes are pretty much the same width as my battery. So would need to design a bracket to cover the whole length of the battery (instead of across it).

The way i have my battery mounted in the box in the rallycar is this,
I have the battery box sandwich plated and bolted to the floor so the box is secure.
I then have the normal hook end threaded bolts and clamp over the top.
The hook ended threaded things are held in by my having to holes crewed in the floor and feed the hook end things up from under the car and then put the clamp on and walah!
This passes scrotumearing and the like and doesnt move at all.!
Hope this helps.

Exact same setup in my car.
Before I added the clamps to secure the battery I just had foam packed around the battery inside the box, this worked ok, but if you hit a big dip or bump in the road you could hear the battery move a bit.
I also had the foam setup questioned at a scrutineering so I just thought I might as well clamp it down good and proper. No more hassles and nice solid mounting

OK, here is my plan for when I actually get a battery in my car. 
Instead of mounting up the box and then putting on the lid, I intend to mount the box upside down. Put the lid on the floor, bolt a metal plate through the lid with brackets for the battery clamp etc. Clamp in battery, then put bottom of box on and strap down. Main reason is much easier access to the battery when you need it, sealing etc should still be all the same.

Unfortunatly that wont work here because the boxes are designed to be mounted bottom down.
Yes sealing should be pretty much the same, but because your using the box in a way it was designed for, it wont pass.
They probably wouldnt care in NZ though.

Thanks all for this info its much appricated!
Hey another quick one.. I wanted to mount the box in the back of the RA28, but not actually directly on the floor.. The RA28's have like metal boxes behind the back seat and along the driver side, this is just so the spare tyre fits and stuff.
I wanted to mount it through one of these boxes. Think thats ok? Or HAS to be mounted through the floor?

This pic might explain better. I wanted to mount it up on top of the rear most box section that actually sits behind the rear seat.

I would guess as long as it's secure it should be ok. They usually test it by grabbing it and shaking it about, so if it passes that test it should be ok

These panels aren't attached to the floor all that well. In an accident the battery would end up punching through the back seat and injuring someone.
I would be looking at welding up a mount to sit under these panels. You could then sit the box on the panels and still have it screw down onto something solid.

Looks good.
What are you doing about sealing the box and venting to atmosphere?
Just curious as I'm still up in the air on what I have to do to get mine engineered.

sealing I'm going to clark rubber to get an insert for the lip of the box.
For venting, I'm going to plus one of the top vents, and use the other to vent through the side of my car.

my engineer will only pass me if i vent the battery box to the outside. im gonna do this simply by getting a length of ciphering hose and taking it to the side quarter vents on the TA22... that way i dont have t cut any holes to vent the hose
anyway i cant see any venting in those pics???

Not vented to outside of car as yet.
Will do that after consultation with engineer about how he wants it done.
Just below the box is a grommet in the floor, so thats where it will be vented to.

I stand corrected. I checked the engineers report the other day and it does say that it needs to be in a sealed box vented to the atmosphere (even tho all i had to do for the engineer to pass me was get a non-venting battery)

just out of interest... why do you all want a
remote battery? seems like a waste of time and
effort unless it couldnt fit in engine bay easily
due to a engine conversion or turbo conversion...
is there any other reasons for it?

Pffft, sif weight distribution has anything to do with it.
Lots of guys need the room to make intercooler piping easier.
Me, I need the room for a 2nd airbox.

Yeah my reason was room in the engine bay.. Intercooler piping and stuff gets in the way of where the battery wants to sit.
Also weight distribution is another reason. As close to the CG as possible the better.

Does anyone know anything about venting batteries not in the passenger cabin?
I read somewhere that batteries must be sealed and vented if not seperated by a firewall. This was just on a battery web site, so I don't want to take it as gospel.
Well I'm relocating mine from the engine bay (in the back) to under the bonnet. So I do have a firewall between myself and the battery and the two compartments are sealed off from each other.
Now the only problem I can see is that I don't know if under the bonnet is vented to atmosphere at all.
So, do you think I need to put it in a sealed box and vent it to atmosphere (so my spare wheel doesn't breath the bad fumes) or would I be OK to just have it clamped down on a custom battery tray?
Edit: or have it on a battery tray and remove one of the grommets, so the whole compartment is like a box vented to atmosphere 
|
Nice car davedave.
I'm doing the same relocation on mine, and my solution is an odyssey battery, since it doesn't give off any fumes at all and doesn't need to be vented or anything, plus being smaller it will be easier to fit into the front.
I had the impression that the fumes are supposed to be vented to outside, even if the fumes wouldn't find their way to the passengers - as someone mentioned above, supposedly hydrodgen fumes from the battery would ignite if there was a spark.
Anyone know where to get heavy duty insulated battery cable for the positive terminal relocation?
