Battery Relocation Considerations For S13

[No Crust Racing]

Morning Gents and others...

I'm looking to relocate the batter to the boot in the S13 track warrior and I'm wondering what the ruling is on a battery in the boot when there is no partition between the boot and the cabin, as the rear of the car is stripped.

It's a standard Calcium hybrid battery, with vent holes in the little plugs where you can top up the distilled water if necessary.

In my head I think you have to have it fully sealed in the boot but with some ventilation to outside of the car, does this sound right and if so how have others done this.

Yep, needs to be in a sealed box with ventilation, so your thoughts are correct

If you put a dry cell in then it's not required.

Dry cell is not on the cards at the minute.

So of those who are mounting ventilated batteries in the boot, how are you venting them to the outside of the car?

Its normally a clear tube the runs from the battery box to out side the car. easiest spot to run it to would be a drain hole in the boot floor.

Ahh, cheers for that

searched the CAMS manual but failed to find anything on the website version.

can a normal battery be mounted in the boot of a 32. It doesn't share the same space as the cabin so is that considered isolated from the cabin? reason I ask is that I have a batt box but it's massive and can't find a nice small one to fit neatly in the corner of the boot so wanted to know if I can just mount it in the corner without the box?

Sealed from the cabin is one thing but don't you have to vent a normal battery to the exterior of the boot space? Or is that only if there's no partition between the boot and cabin?

have a look at how R34 GTRs do it. they have a little vent tube that exits through a small hole (with rubber grommet) in the boot floor. with a battery like that you would probably not have to box it. places like battery world etc have those batteries. they are basically a normal battery that are sealed on top with just one vent for overflow or gas and it comes with the tube already attached. that's what I'd use. they are designed to be used in the boot space of cars (like R33 and R34 GTR etc).

ah ok. I was thinking I could get away with it as 33 and 34's have it basically sitting in the boot. Didn't know about the different kind of battery.

[Beer Baron]

yeah 33s and 34s are sitting in the boot but they are sealed on top and have an external vent/drain pipe. it's just a little clear plastic pipe about 8mm diameter and I guess they've just covered the top of the battery with a plastic cover with just the single vent hole with pipe on it instead of little vents on each cap. they are easy to find and no more expensive than other batteries of similar size. not sure if you have battery world in melb but if you do go there and ask for an R34 GTR battery and you should get what you need.

rang CAMS today and they said just mounted in the boot is fine. Nothing in the manual to say otherwise.

[Beer Baron]

cool. personally though I'd still buy one of the batteries with the vent tube on it. they are not really any more expensive than other batteries of similar quality and size and it's nice to have the knowledge that if it does need to vent it's not going to do so all over your wiring, or surge tank or whatever.

they look like this:

see the little picture of the race car on the battery? just above it is the point where the vent tube connects. most come with the tube too. any battery world shop will supply one.

edit:

found an even better pic. you can see clearly where the drain tube attached on this one.

Thanks mate. I will get one of them next time or maybe even a dry cell.

Seriously, juest get a dry cell. It depends on how many amp hours you think you want but it can save quite a few kgs.

This is just on Amazon. Proper Braille motorsport battery.

Braille Battery 11.5lb, 904 pulse cranking amps, 360cca, 15amp/hr 1yr warranty - Left Side Positive Terminal

Cost is $160 + freight.

You can get other larger capacity (amp hours) locally for not much more.

[No Crust Racing]

The one I got for the Silvia was from a local guy, $150, 780PCA, around 280CCA, weighed a kg or two less than what I had.

Perfect for a little 4 banger like mine. I reckon it'd start a small 6 easily enough too.
