Bought a new battery today, my current one was a bit tired, but then it's lasted 8 years, which is pretty good.

I talked to the battery guy for info, saying that in the 'old days' that several UK cars used the uprated version of the standard small battery (I'll call this STDX, 300CCA), and he said, well actually the NS60 *is* that battery, with a couple of very minor size tweaks, and still used in quite a few Jap vehicles, and the company recommends it for a lot of British classic cars.

He showed me a couple of the more common ones side by side for comparison, and really the only noticeable difference from the STDX is that it's taller, and just slightly longer (a few mm). So it's perfect for that narrow slot in the wedge. [NB, all the V8 ones I've seen have a dent in the wing, and use a DIN55 or similar (500CCA) ]

So if you're stuck for a battery, Hella cross reference is NS60A, and it's 430 CCA, 75 RC, and it fits perfectly !!

Excellent, bookmarked for future use. No doubt I'll need one if I ever get the 200 going again.

For those of us on the left side of the pond, we can use a WalMart MS24 battery. This is a marine battery with 625MCA. I have no idea of the difference between Cold Cranking Amps and Marine Cranking Amps, but it is a powerful deep cycle battery, good for those of you with cold weather.

A deep cycle battery is usually used for continuous dischage whereras an automobile battery is better for the load from a starter.
It'll work, but you will pay more for a deep cycle battery.

I also don't know what Marine CCAs are...smile Lower I guess.

Found some cross references for the NS60A, in case they are any use - these are from Hella web site, so don't know if sizes are the
same or not, I hope so....

PNS60A PANASONIC BATTERIES
NS60AU ULTRA BATTERIES
NS60ZAU ULTRA BATTERIES
51 CENTURY
126PR EXIDE
X60C EXIDE
KN11 LUCAS
MF55B24RS SUPERCHARGE

and NS60 battery is sized (on web site) at 125mm wide, 235 long, 220mm high.

There is an NS60L which is the 'left handed' version (i.e. polarity reversed) if you need it.

Jeff,

I did some homework. Here is the answer:

"Cold Cranking Amps (CCA) is a test conducted at 0 F (-18 C) for 30 seconds without falling below 7.2v at the battery's CCA rating.

Marine Cranking Amps (MCA) is a test conducted at 32 F (0 C) for 30 seconds without falling below 7.2v at the battery's MCA rating.

To pass the CCA test, a 700 CCA rated fully charged battery would be chilled to 0 F (-18C), then load tested at 700 amps for 30 seconds. To pass its rating, it has to maintain at or above 7.2 volts.

To calculate the MCA rating of a battery compared to its CCA rating, multiply by 1.25."

So mine is equivalent to 500CCA. This is plenty.

You are right about Deep Cycle batteries primarily being for trolling, but this has plenty of power for engine starting. The main advantage of deep cycle is that it can be neglected (my field of expertise) and run flat many times without need to be replaced. Car batteries do not give us that luxury. But it is much heavier too.

And WalMart used to have a great warranty; free replacement after 18 months. Guess what I did at 17 months!

This battery serves two purposes; the TVR and a house battery for my boat (which wiuld also start the motors in a pinch)

Anyone got a pic of a fitted battery in a NS battery S1 wedge, so I can double check position.

WalMart batteries are made by Johnson Controls, who also make many OEM batteries.
