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)?

Glenn:

There are a combination of tests, none as decisive as we might like:  Load
the battery bank and test per cell voltage (more often we find warm
connections revealing related problems).  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.
