Battery location???
Discussion
OK. This may be a silly questions, but after lots of thinking I have decided that my S3 battery will be placed in the boot, not under the bonnet. So my silly question is "does it matter which side it goes?" I'm tempted to put it on the passenger side (V8s is on the drivers, IIRC) which I know is closer to the petrol pipes, but otherwise cannot see why not. Am I missing something obvious?
Also, I'm thinking a battery of 60Ah and about 300A cranking current should be ok.
Any thoughts folks?
Cheers. Tony.

If you're sticking with a "full size" battery I don't see how it will fit on the left if you carry a space saver?
I located mine on the right, space saver is on original mounting and roof panels still fit in. Maybe not ideal weight distribution (it's on the right originally at the front) but I make allowances in my braking and cornering speeds for the imbalance ...........
If you're going for a clever dicky little race type battery that will you a few more location choices ?
Thanks Mike M and Mike P
It was the weight distribution that prompted me to look at the passenger side, and I don't have any bracket for the space saver. Presumably I could locate that elsewhere but then weight is probably redistributed again! I'm probably going with a standard sized battery at this stage of thinking. It's just that the starter and fuse box is on the drivers side, so slightly shorter, longer, cables perhaps

a) why bother?
b) it takes up a useful space in the boot and leaves a useless hole under the bonnet
c) more cable lengths
d) you have to be certain of emergency boot release if the battery goes flat
It would not make much difference to weight distribution on my car if you saw the amount of stuff in the boot and not much if you dispensed with the spare wheel.
Just interested to know why people spend the time on this mod.

Didn't the V8S have the battery in the boot?
Yes, It's earthed directly to the chassis immediately underneath it, and the main power cable goes forward to the starter solenoid, which is used as a distribution point for the rest of the car. Worth using a big cable since it's a long run.The point about opening the boot with a flat battery is a good one. It's worth making sure that you can get at the mechanical release just in case, but in practice I've always been able to jumper power to the main power terminal on the alternator with ignition on and the boot release pressed.

Spare little corner, I don't miss itTurboTony said:

Yes, but the S is not a very big car so still only a couple of metres, not a problem (I used 35mm cable)TurboTony said:

I have secret cable release or can jump power onto alternator terminalTurboTony said:

Because we can .... It is just my opinion but I think the battery looks a proper"after thought" stuck up in the air on a hotch potch bracket right down the front
The main reason for me relocating the battery is that my posh new exhaust system takes up part of the usual space for the tray under the bonnet. It is 'just' still possible to put there but the boot is an obvious option - plus, I would need to make a new battery tray anyway.
Interestingly, the racing driver instructor at Blyton Park (shameless plug for upcoming track day on 16 June
) insists from a weight distribution point of view it is best in the front over the wheels.
All good food for thought!

Drivers side in the boot as well, ran 70mm sq cables to the front, ran both live and ground, put a ground to the chassis front passengers side and one to the rear chassis just under the battery. Just bolted a 10mm exhaust bobbin to the engine bay for the live pick up point. Engine gets a solid ground to the cable.

I'm with you on this one. Can't see the logic, personally. Unless you HAVE to move it because you need the space for a turbocharger, or something!b) it takes up a useful space in the boot and leaves a useless hole under the bonnet

I'll have a go at mocking up later today. I pretty well have to move the battery somewhere because of the exhaust being in the way so the boot is better than the later TVR approach of passenger footwell in my view. The passenger side of the boot has less room between tank and side of body so it may be tight, but worth looking at.
