Thank you for posting this John. There's a LOT of
words here . . . some of which are conflicting.
It's going to take awhile to do an analysis.
In he mean time, tell us about your airplane. Is
it wired per any of the z-figures? What's your
bus voltage run in flight? Your failure rate
is too high to blame on a working maintainer
of any brand. Have you measured the maintenance
voltage of your maintainer?
As often as you appear to be flying, there's no
driving concerns for using a maintainer at
all. I'm thinking something else is going on
with your system that's generating these battery
failures. Check that regulator setpoint.

The airplane is an RV9A using Z13/8 and dual P-Mags. In flight voltage
is 14.1 to 14.2 and I have not measured the maintenance voltage of the
maintainer.

At this point, I plan to not use the maintainer and fly often enough to
keep the system going. I will test the maintainer on an old battery and
see what voltages I get.
