Thread: S1 300Tdi battery

could it struggle to start it because the diesel is having problems not the battery?

650CCA CAT battery will fit.

Also check if someone hasn't engraved the date into the battery case. Can't remember the recommended size battery, but 450 seems a little small.

* How many CCA is standard for the 300Tdi?
* If I relocated the power steering fluid reservoir would the N70ZZ fit to the right of the radiator?
* Now that they don't stamp the "bought date" on battery posts, how do you tell its age? The bar code??
Cheers in anticipation

I have a supercharge gold 670cca battery as my main and is biggest i could fit and use the old main as the auxillary, at -5 c you might need some form of insulation on the battery.

Thanks for the replies.

At 670CCA the Supercharge battery sounds the go, and the idea of the Exide as an auxiliary is appealing. What's the reserve CCA on that battery? I've had Supercharge batteries in other vehicles and they've been excellent so I might go down that road again. I'll also check for stamps on the case of the Exide.
No, the diesel I'm using wouldn't be a problem as in Tassie the winter blend would be in the servos by now. The problem is slow turn-over. -5oC events happen where I live about a dozen times a winter and we can get to -7 at times, but my other diesels seem to handle it OK (except my Mk1 Golf diesel which needs new rings and deglazing but I can bump-start her ).

Cheers.

Avoid a calcium battery.

I got suckered into buying them for my '95 P38A Rangie and the '95 300Tdi Disco.

The alternator on older cars isn't designed to charge them so after about 12 months they die. I didn't know the reason until recently (from info given on here) so I've actually replaced a dead one with another.

A standard lead acid lasts a lot longer.

Oh, mine has an N70ZZ in the LH position - it's the second battery.

Want pics?

With slight reshaping of brackets securing pipes between battery and radiator, I managed to fit a larger battery in an SI 300Tdi. As ownership of that Disco has now passed to others, I'm not sure what model or size battery it was but came out of my Defender so would have been pretty close to a N70ZZ.

Someone had done that to mine as well and fitted a N70ZZ. But they left the pipes unsupported and I was worried they would fracture whilst the car was up in Derby with my daughter - so I sourced some new clamps, straightened the brackets and pipes, and fitted a smaller battery
