Hi all,

Relocating battery to the boot, anyone done it? I wouldn't have normally, but the new 072 Halfords battery I've bought is too high to fit under the bonnet/wing and it got me thinking? Surely it's better for weight distribution to have it mounted in the rear? IO fancy a nice little trimmed box in the boot down low. I can tap into the 12v Red feed to the fuse box easy enough I think?


Anyone else done it?

Take it back to Halfords. They WILL change when you point out that they have changed the design. You need the OLD style one.

I thought about doing this if space became a problem with the LS1 conversion. Basically its not too bad to do, like you say link into the main cable which feeds the fuse board. There's a good earth point behind the fuel tank but easy enough to make a new one. At the other end everything would stay as is eg starter motor and alternator connection just replace battery terminal with large terminal block and bolt battery earth terminal to the chassis. I don't think volt drop will be a problem, BMW have been doing it for years. smile

It's a good idea, we'll be doing it on Trackcars recommendation when we do the body off rebuild. smile

Get that weight further back and lower down, win win.

What size are the cables that supply the fuse box then? i doubt theyre big enough to take cranking amps, but i have been wrong before.......a long time ago.
I relocated the battery on my golf project, the cables run under the car in a kevlar sheath and are as thick as your finger. Just something to consider, we dont want another one melting!

I have a Jag and an Aston which both have a boot mounted battery as standard.

I have put another battery in the boot and connected both of them together. Since doing this the car is alot more reliable, turns over much quicker and starts every time with no need to keep charging it up.

You left the car for any length of time? Sure i read on a car audio forum (lots ov audio nuts use two batts, was a wee while ago now mind) that if you simply connected the two batterys together they would discharge into each other!! Mabye my memorys going and iam speaking crap tho lol

Yes I leave the leave the car stood sometimes for a week or two and sometimes just use it for short journeys and it still works! I have a couple of amps in the boot to power the stereo but they are only small. The effect of two batteries is that you end up with twice the cranking ampage,I have two 600 amp batteries, and the altenator should be able to cope. This gives you a far more reliable car.
