What vehicle. If its a large high compression motor then you will need more power. But most batteries have more power than most require to start so if you are only down about 100 and live in a warmer area I see, then you still got a good amount of life left.
Unless you live in a really cold part of NM i'd say that CCA testing is good way to 'justify' selling someone a new battery, but if repeated tests show the CCA dropping fast the battery is on the way out. If you live in southern NM and the truck is in good shape, with good flowing synthetic oil I don't think you'll miss 100 "CCA". As just happened to me with an 8 year old Toyota OEM battery, though, these new battery designs can start an engine a number of times in a day and then be dead as a doornail that night. Might be worth getting another test at a different vendor, it doesn't take much excess resistance in a high current load test hookup to read a bit low.
When I see CCA I twitch...Used to work for Corrections Corporation of America...twitch twitch

I realize that there are other considerations at work, but is there a good rule of thumb for replacement based on tested CCA?
Is it an Exide? Then even new they would not crank what they are rated for.
Keep in mind, your battery is still better than a 600CCA battery. If its doing the job let sleeping dogs lie

OK. 60% then, 450 or so CCA.
The dealer of course would have it at 550, just like they say that you should change the oil every 5,000 miles.
It's the original Motorcraft battery, almost 5 years old.
I thought that my short haul driving was causing it to deteriorate too fast. So I put It on a float charger. For whatever reason that got to be a daily habit. CCA deterioration has almost stopped.
Now it's like a competition. I'd like to see how far I can go but I don't want to leave myself stranded to find out.
Based on what I'm hearing from you guys, it will shake apart before it chemically poops out.

Bear in mind that battery testers don't really test CCA, they infer it by testing at ambient temperature and doing some calculations based on assumptions rather that doing the actual test in a freezer at 0 Deg F.
Surely that has to mean the tests aren't super accurate.
