Thanks for the reply William, When you load the battery bank, are you using the inverter as the source of the load (obviously with its loads), or do you use an independent DC load like a carbon pile (auto battery tester)?

Measure the at rest voltage. Measure voltage over time at load. If you are serious about this, establish base lines when batteries are new. Good luck.
