Hi...i am a new user here. I only know that if their meter said it was below a certain capacity we had to put in new batteries.  I never did understand exactly how those meters determined capacity - maybe did a quick load test and conpensated for temperature ?

If you are talking about the small handheld sealed lead acid battery testers -  I think they were temperature compensated and they probably just calculated the batteries interenal resistance and voltage with a quick load test. I never thought they were very accurate because brand new batteries never tested 100% either.  And two different meters would give two different readings on the same batteries.

The good thing about them was I got to get good used batteries that they said had failed.

Brand new batteries are never at 100%. It takes several cycles to finish building the positive plates.

good point
With that in mind maybe the worst thing for those new batteries was just putting them in a system that floats them and never cycles them.
