What is this???

I was inspecting the battery compartment (on my 2.5 lux - battery in boot) this evening as a previous inspection revealed that it was loose and rattling around a bit.

Anyway there was a cylinder thing about the size of a tennis ball immediately behind the battery which has a 6" long tube on the top the the words "only batteries with common gas vents to be fitted".

Apologies for my ignorance but what the hell is this. It is not connected in anyway.

Cheers.

As the battery is in the passenger compartment the canister you've found should filter/remove the gases batteries can produce, the pipe plugs into a hole on the end of the battery.
 
Here's a pic:

Much appreciated Peter! Never seen anything like this before. So does it matter that it was not connected to anything. Are the gasses so bad?

 
I think it's Hydrogen they give off when charging (I'm sure someone will correct me if that's wrong). So I guess it's just to preventing a rather big bang... Can't think it's terribly likely, but best to be on the safe side and connect it up!
 
When the battery is charging hydrogen gas is given off. This must be vented to the outside of the vehicle as it is highly explosive when the correct ratio is reached with atmospheric oxygen (hence why no smoking near charging batteries!!). The little tube should be connected to the vent connection on the battery which will then seal the vent and the gas will be collected and vented harmlessly to atmosphere, as it is when the battery is under the bonnet in a relatively open and well ventilated space.
 
The only problem with this is that some new batteries (Bosch silver seal for example) are sealed units. I spent half an hour trying to find where to connect the vent tube before I gave up and asked!
 
After looking at that pic I can now see why it was that when I bought my battery from Halfords I couldn't shut the bonnet any more.

My flabber is ghasted that bearing in mind the weight saving you`ve made so far you dont have an Odyssey/Red Top battery in there - shame on you [:eek:][:eek:][;)]
 
:ROFLMAO:

[:)] I do, but it's not fitted just yet (the aluminium bracket doesn't quite fit in the standard place, and I'm planning on putting it behind the passenger seat in the long run anyway. To do this properly I need some studs welded in place in the floor to screw it in, so it's waiting till the next bodyshop visit.

I was going to ask the same question... BUT you beat me to it....[;)][;)][;)]
 
Interesting. My S2 doesn't seem to have such a canister.

I guess it was either removed by a previous owner or never fitted. I think it may be a sealed battery in there, which may explain the removal ...

Think how much weight youll save in positive cable too... [;)] Id be interested to see how you you secure the battery box Pete, assuming that youre going to use one.

My car isn't even as clean as that on the outside never mind the battery compartment [:eek:]
 
Graham,

Dunno. There may be a pipe on mine, to the outside world but which isn't connected to the (sealed) battery. I'll have a look next time I am out there ...

Naturally the weight saving hadn't escaped me [;)]
No battery box, it's just an aluminium bracket that secures it rigidly, I'll make sure the terminals are well covered. I'm hoping the bodyshop can weld in some plates with nuts underneath the car (like the plates used for mounting the 6 point harness) and then the cover can screw into place into those. Not sure where I'm going to put the master switch though...
 
Id suggest going with a battery box: there a plenty of good reasons but I cant think of a negative. Id also suggest locating the master switch in the scuttle area on the drivers side, along with any extinguisher pulls. If I can find a picture I'll post it up for clarity, but simply put you mount the switch in a steel sheet bracket and drill the handle. Secure one short (for the exterior pull) cable and one long (for the cabin) cable through lug of the key. Mount the exterior pull handle and the exterior extinguisher pull handle in a single aluminium bracket which should be mounted adjacent to the bottom edge of the windscreen glass.

On a series two car I would mount the cabin pull handles into a mounting plate inserted into the rear of the centre console; line-astern, with the cables routed/secured along the NS of the transmission tunnel.

Id always buy the longest 'T' pull handles, because theyre only a £1 or two dearer than the shorter parts and if theyre too long then you wont wont have to compromise on their routing...
 
The above assumes that you only have single seat btw... If not then Id mount them cross the car, again in the odments tray area, witht he cables secured to the transmission tunnel forard and then routed up and through the scuttle panel.

For security I site the battery box against the rear 'seat' base and Id always mount my bottle longtitudally, as opposed to transversely.

Is your DME still under the floor?
