There isn't one really.

You'll need to get the physical size and terminal orientation right for the location in the vehicle.

After that you'll need one with enough CCA (cranking amps) to get it started. I'm running with 440 CCA at the moment, but the vehicle starts easily. You can go up to 760 CCA if you want to spend the money, and think you might need to run the battery for a while.

It depends for a start on whether it is a petrol or diesel, but basically the battery type it was designed for is no longer readily available (and no reason to try and get one unless you are doing a finicky restoration). For practical purposes, it should have one that has the terminals on the right side, and the height and width to match the carrier. Within these restrictions, anything that you can buy is suitable for the petrol, for the diesel, you probably need to pay a bit more than the cheapest you can find, and even with the petrol engine it will last longer and stand more abuse if you get one that is not the cheapest Chinese special.

Having said that, I use a 90AH, 750CCA battery - the same as I use in the County and the tractor, both of which have far greater starting demands (Isuzu 4BD1 and Perkins 6/306), so that the batteries are interchangeable. (Actually, the one in the 2a at the moment was the one out of the tractor, that now has the one out of the County, that now has a new battery!)

As stated, depends if petrol or diesel, and when built.

I have found N70ZZ size to be best bet all round, and have, or have had, them in SII, SIIa, SIIb, SIII, Deefer and boat. (Calcium calcium type for boat - truly excellent and exxy).

If the carrier is designed for one six volt battery, and is too short, it is an easy job with a grinder, welder and bit of 10# plate to extend it about a few 25mms (in the olden days we called em inches) with no clearance problems.

And, again depending on date, it may have been positive earth. It is an easy job to change polarity on the battery to negative earth, and not an onerous task to change the few polarity sensitive things to work correctly.

And while you are at it, this is the ideal opportunity to change the old lucas generator for a slightly more modern alternator. Although the old bosch's may be getting a bit scarce at the wreckers now. I had to pay $40.00 for the last one I got!

Another vote for the N70 here too. It's what I run in the S1, S11 and 2 in the Defender.

As Peter said.
Mine has a Caterpillar battery approximately N70 size, fits nicely on the tray. My IIa was originally +ve earth now -ve earth. Make sure you get a battery that has the terminals on the engine side for your set up or else the terminals will be perilously close to the bonnet support arm when the bonnet is lowered. I have the wrong sided battery, but it was a gift and an expensive one at that, so just have to be careful with insulation.

;) Thanks everyone I was thinking about the same size that I have in my Deff N70zz.
I had a smaller one that was from another vehicle but it didn't last the distant's
That will teach me for being cheap:angel:

N70ZZ for positive earth, N70ZZL for negative earth.
