Sounds like these are start batts, not deep cycle batts. All deep cycle batteries I'm familiar with are rated in AH, not CCA. All start batteries I'm familiar with are rated in CCA, not AH.

I'm ignoring all those in the middle that are considered "dual purpose" which seems more marketing that material.

Sorry I can't help with load testers. I'm more of a specific gravity guy. Some 'maintenance free' batteries have removable caps beneath the label, making it possible to check the SG.
