74 Duster 360-When it's time for a Battery what do you guys look for in terms of Cold Cranking Amps
 
Figure out what group number fits (maybe 24). The the reserve capacity is a good indicator of battery quality…look for 110 or higher
 
I go for the highest reserve capacity and best warranty I can find for the given group size.
 
Just stay away from dual terminal type batteries like the 34-78 style.
Stick with a post and get new, proper application battery cables. no temporary cable ends ( note "Temporary")
Temporary are just that.
If you want trouble free battery to starter and solenoid connections, get a new cable. Custom fit $90-
$ 160. shop around.

Batteries are really expensive everywhere, except Costco. I don't like Costco for other reasons but I make an exception when it comes to buying batteries. LOL they sell Interstate, pretty decent... and 100 bucks cheaper in most cases.

I'd say I want at least 650 cold cranking amps
Though you could get by with a little less.
 
I just replaced 3 batteries in 3 of my classics. I went total cost saving, and bought 3 from Walmart for 69 bucks each. Group 34, top post, about the same size as a group 24 but the 34 is a touch shorter (goodie goodie..lol). The ones I replaced were from Farm & Fleet, couple went about 5 years and one about 2.5 years.

They whip them puppies right over... I think 600 CCA ??

Yep, WalMart specials. I've got two of them currently, and so far they've outlasted two way pricier batteries in my other cars.
Used to have a local battery service that built their own batteries, and I used those for decades- but they finally had enough with the regulations and shut their doors. Wallyworld so far is the best bang for the buck replacements that I've dealt with.
 
I know the major manufacturers can build a cheaper model for Wal Mart but I have gotten good service out of them mostly in my tool truck. It was hard on engine start and coach batteries.
AI Overview



+3

Walmart's EverStart batteries are made by several different manufacturers, including Clarios (formerly Johnson Controls), Exide Technologies, and East Penn Manufacturing. The specific manufacturer can vary by location and product line. Walmart uses a private label model, contracting with different manufacturers to produce batteries under the EverStart brand.

Here's a breakdown:
    • Multiple Manufacturers:
      Walmart doesn't have one single factory for its batteries; instead, they partner with several large battery producers.
    • Clarios/Johnson Controls:
      This is a significant battery manufacturer that also makes other well-known brands like Interstate and Diehard.
    • East Penn Manufacturing:
      A major battery producer that also supplies other retailers, like O'Reilly, and makes batteries for various private labels and original equipment manufacturers (OEMs).
    • Exide Technologies:
      This company is another known producer of EverStart batteries and is one of the world's largest lead-acid battery manufacturers.
    • Varying Suppliers & Location:
      The manufacturer for an EverStart battery can differ based on your geographic location and even the specific battery model in stock at a particular store.

You live in Florida CCA is not important, I would go for a lower CCA for more acid in the battery which is important to keep the plates cooler.
 
This website claims the Ah to CCA conversion for AGM ratio is higher than for traditional batteries.
In other words to get the equivalent of a 48 A-h Group 24, will be around 336 CCA minimum, but in an AGM we would want at least 384 CCA and maybe as much as 456 CCA.

How to Convert Amp Hours to CCA: A Comprehensive Guide - Global Batteries

How to convert amp hours (Ah) to cold cranking amps (CCA)? Use the formula CCA = (Ah × 7.25) + 0, though real-world results vary due to battery chemistry and temperature. For example, a 100Ah battery calculates to 725 CCA, but actual output depends on plate design and electrolyte strength...

From the shop manuals it looks like the higher compression engines got optional 56 and 70 Amp-hr batteries in '68 and '69.

Does it fit in the factory tray?
 
For a low comp ratio small block, I would use a 650 CCA battery.

24C used to be "the one." 24F is Ford, which has bottom mounting clamp flanges and reversed terminals

Last time I went into a "parts store" and asked the "parts man" for a 24C he played dumb.

I sold auto parts for 14 years at two different stores. I used to know WTF I was talking about.

Costco thought 24 and 24 F were the same. They only carry the 24 F. Only the local specialty battery shop called the 24 a 24C.
 
Went to Wal-mart a few days ago and picked up the group 34 318willrun mentioned. 69 bucks and just rite
