    May 1996 Build Discovery 1 TDI - What Battery?

    Hello All,

    What size battery does a May 1996 TDI Discovery take? The car did not come with a battery - so there is nothing to go off to narrow the field down.

    I went to some different battery places online and they vary between an Exide XN50ZZMF 720CCA while Century suggest N70ZZXHD CCA 735.

    I went to fit a N70ZZ that I had at home for my Series 3 with a Holden motor in it and the physically did not fit the Discovery - or maybe I was holding my tongue the wrong way?

    Kind regards
    Lionel

    Nah! tongue was definitely the right way 'round.
    A/C pipes in the way for a ZZ to fit.

    a non ZZ 70 size will fit tho.
    eg. Century NS70X series with the correct pole orientation.(I think the LX version has the poles the wrong way around)
    (only problem is I can't recommend Century from my personal experience with them tho)

    I got the Century based on two things. Immediate availability on the day I needed it(public holiday), and that it's supposedly rated at 720CCA.
    The CCA rating feels about 50% ambitious compared to when I fit brothers Optima 34 redtop(rated at 800).
    The Tdi cranks much faster with that redtop in it than the mere 80 additional CCAs would have you believe it would.

    SO the Optima would be closer to about 1000CCA(by comparison) or the actual CCA of the Century is (sounds/feels) closer to 600ish.
    Note tho I have tested(I have a tester) the Century and it still tests at about 720-730 without problem.
    Also note that the difference in starting is only from cold start on a cold-ish ambient. Once warm, the Century starts nicely, and feels more like a 720CCA battery.
    With the Optima tho, it sounds faster cranking irrespective of the ambient temp.

    SSB get good comments about them, and I've looked into what they have as a starter battery, and found the ES70 and SS70 from their range will fit.
    No idea if those are any better than Century that I have at the moment.

    Last note, if you move the air filter box from the std location, you can fit a 70ZZ in the LHS battery space without moving the pwr str reservoir. It's tight, but does fit.
    I currently have a no-name battery there, the same size as my Century as my aux battery.

    Sorry for being a bit late. Cold winters in Tamworth NSW made cold cranking 300Tdi so slow and erratic even with largest capacity non-ZZ70 main battery, that I had to do something.

    Snorkel and no LHS front filter box in my 98 D1, but had to move the steering res with a small bracket, and kept ZZ70 size deep cycle flooded, sealed then (under bonnet rated) AGM in there. They run only stationary loads, but I had to jump them to the main battery to crank or start on very cold mornings.

    Largest capacity ZZ70 size main battery now starts the diesel easily. Got local auto air con mob to make up and route new A/C pipes out of the way. Fittings are unique and aluminium, so they had to cut and voodoo some fittings. About $600 all up.

    Final result: ZZ70 fits in main battery tray as intended; A/C pipes happy and safe; cranks much faster, no probs in cold. $600 very well spent.

    Hope thatÂ’s helpful. Cheers
