Having a higher CCA on a new battery is pretty standard especially if you test the CCA in different conditions. I know, according to the testers, that CCA is the measurement of CA in colder conditions but if the battery isn't cold enough, the only thing a tester can do is approximate what it should be at the current temperatures. Typically warmer ambient temperatures will result in higher CCA measurements.hightech wrote: ↑Nov 16th, 2018 1:28 pmThose chargers are great if the battery is in good condition. As Craftsman has mentioned, those chargers only measure the battery voltage not the overall health. The tester I suggested will give you battery health and CCA count. Keep in mind that a NEW battery will rank as being higher than the stated CCA. I just purchased a EverStart MAXX-24F battery from Walmart (Made by East Penn Deka) that is listed as 725 CCA. As you can see by the pics, the CCA is far more than that.
Once the CCA starts dropping below the stated value and the battery health gets lower, this is when you should start shopping for a new battery.
What I suggest now that you have a brand new battery is to charge the thing FULL and measure the CCA and record the ambient temperature you measured it at and stick it to the battery. That way, you know if you test it later, what the battery was like when it was new and not what is the rated CCA. I would also record the IR number and the voltage as well.
