EVERY WHICH WAY BUT LOOSE...
Establish gravity right off the bat. Herb Tarlick is in charge of acid densities now. With industrial batteries initial fill specific gravity can range from 1.260 to 1.280
With car jar batteries, things get wild. 1.275 to 1.290
Total agreement with establishing impedance value when new then follow up with trends and tendencies.
Same with load tester after battery has undergone min (8) cycles. Difference is subtle but with digital meter resolution, it becomes a tool.
Thanks to a very astute member's link and most welcome post, informal capacity testing of AGM has become rational and reasonable
