WHAT BATTERY SPEC/CCA'S ?

[Dodgy Dick]

Can any body please advise the correct battery fitment for a 69 Fury 318 Auto and/or recommend an upspec variant,? (the car is currently fitted with a 520 CCA Battery but this seems awfully too small to me!)
Thanks

Can you please explain the US Group Battery number/designation/spec.
We in OZ are not familiar with this system of Group rating of battery size/power/type. Etc

Are you looking for battery dimensions? For the restoration battery, in the link you will see the dimensions.
10 1/4 ” L x 6¾” W x 9” H TO TOP OF POST.

converted to metric:
26.035 cm Long by 16.1036 cm Wide by 22.86 cm High to the top of the terminal posts.

Cold Cranking Amps are across the board for replacements from 500 to 800 or so. That's more of a preference. Yours with 520 CCA's should be fine but is on the lower end.

The battery "group" is based on physical size and orientation of the posts. A 69 Fury is going to have either a group 24 battery or a group 27 battery. Here's a chart: BatteryWeb, Inc. - BCI Group Numbers, Dimensional Specifications, Polarity and Terminals

As you can see, the group 27 battery is a little longer, thus giving a little more room inside for bigger or more plates and more acid. The group 27 has one more plate than a 24.

CCA (Cold Cranking Amps) is a measurement of how much amperage a 12 volt battery can deliver at 0°F (-18°C) for 30 seconds and still have at least 7.2 volts. Obviously, the more CCA, the more powerful the battery is.

The thing that people don't think about is that this is what the rating is when it's brand new. The battery starts to deteriorate with age and if you were to test that battery for CCA when it's 5 years old, you aren't going to get that same amount of CCA.

The question is if your battery rating is high enough for your car.. That's easy to figure out. Does it start your car every time? If yes, then it's plenty big enough to do the job.

If you needed to replace the battery, then I might suggest going to a battery with a little higher CCA rating, but that's up to you.

Learned many, many years ago, that the #1 thing that kills a battery is when the material on the plates sluffs off and accumulates in the bottom of the case. Once this material builds up to reach the bottom of the plates, you end up with an internal short and it's game over. So as much as CCAs are important with regard to how much power the battery puts out, long life depends on the amount of open space beneath the plates in the battery case. My personal experience with Interstate batteries has been much better than other locally available aftermarket/independent brands.

Interstate usually has a good product. My experience has been good.

There's really only three major auto battery manufacturers. Johnson Controls, Exide and East Penn.

Johnson Controls is the largest auto battery manufacturer and they own Interstate. They also make DieHard, AC Delco, Duralast, Advance, and a bunch of others. I've read that Johnson Controls makes the Interstate battery and Toyota's OEM batteries with different plates and are a better battery, but I've never seen that confirmed.

East Penn's house brand is Deka. Both East Penn and Exide make batteries for a lot of the other parts houses.

Thanks for all the info,Big John's Chart was a leg up. We in Oz mostly concentrate on getting the most CCA power rating in the best dimensional fit battery. However the more CCA's means more dollars. In my case I thought 520 CCA was inadequate for my V8, really being more suitable for a big 4 or 6 Cyl car. It certainly looks small in the battery "cradle"
I will decipher the size (group) chart John provided and then look for the most CCA available here in that 69 Fury dimensional size, all good and thanks.

Vibration and heat kills batteries. Cold plays in as well.

Normally a lead acid battery lasts about 3 years with no problems. If the charge is maintained the battery can last 4-5 years.

Across the pond here the go-get-it battery brand is Bosch. For a 440 I chose Bosch Silver S4 #S4 029.
