Thread: Dual battery setup - 2004 D2 TDI

As far as the turbo goes, yes it is a significant source of heat and "unprotected" lead acid batteries may well suffer......

The thing with the Aedofab tray is it was designed around a V8 (as there is no TD5's in the US), which has no engine ECU in the same location as the TD5..........and although its not that protected where it is in the factory "box", its better than being just slapped on the back of the rear plate of that aedofab tray.

Prolly not a big issue, but putting on the passenger side also spreads the weight evenly.

That and the cost was what put me off - I would have had to replace my starter as well. I did investigate using my existing starter and mounting the auxilliary next to it but it just won't work.

The other reason for mounting it in the rear was that I could use a larger capacity battery - 55AH limited the amount of time I could spend in the bush without driving to recharge the battery. I would have like bigger but having more weight behind the axle limited me to a 75AH battery - I did not want more than 23kg back there.

Ive got a V8 and have blown 2 batteries over the last 3 years or so. I would recomend having it anywhere but up the front. It is interesting about the optima though. I have often wondered if i could mount one up next to a chasis rail. Lots of space down there, i could protect it somehow and it wouldnt take up any space in the rear. Anyway its just a thought.

I was just thinking the same.
They have sill tanks so why can't a battery tray and cover be made to sit underneath in the chassis rails.
