Thanks Tump and to everyone else that offered input. I have purchased
a Biddle M-BITE impedance tester. After I have learned to operate this
multi-buck unit, I'll give a report on how useful I think it is for RE
system batteries.
I also use a West Mountain Radio CBA II with the 10X amplifier that
let's us do temperature compensated discharge tests up to 500 watts to
verify the actual AH capacity of a battery. The impedance test should
only take seconds per cell so I hope it replaces this discharge method
of testing.
Kindest Regards,

I have been using conductance technology for 10+ years and it is a
great tool. I can test a bank of 24(up to 100) batteries is less
than ten minutes and get a print-out. It is only a very good guide
that has the advantage to be used without disconnecting anything.
The more you use a conductance tester the easier it is to learn the
short-comings. It has the ability to test a battery, or a bank that
is not fully charged. It is also great for matching a used battery
to an aged bank. It I have a question and suspect a particular
battery, I still will use my carbon-pile or load bank along with
other indicators. I have been using the Midtronics and am currently
testing the Auto Meter.
I use both Automotive and SLA(ah)units of different sizes. The
prices do very but as the old adage goes you get what you pay for,
my regular unit is an $800 Midtronics plus a $400 printer. I am not
a part of the wrenches group, nor am I very good with email. I would
love to join but probably can't as I am only a battery / energy guy.
