This follows pretty well what is published here:
http://www.zbattery.com/zbattery/batteryinfo.html
If I can influence this test....there is such a huge difference in 9V
batteries that to buy a low-performing one for anything critical seems
almost dangerous. Perhaps you can look at 9V batteries in you test?

Aha! The repeatable experiment reigns supreme.

Hadn't considered those puppies. The same sale where I picked
up the AA cells has some 9v. I'll drop by and pick some up.

My wife's view on it is that it is an expensive baby sitter, but with it
she always knows where I am at, just open the garage door and I am
there, granted I am spending more money as I am standing there, but she
thinks it is better than a boat, which falls into the other expensive
hobby!

Do you mean you've been able to convince her that it was
anything else? Hmmmm . . . I did hear a comment from a wife
at OSH a number of years ago wherein she expressed thankfulness
for her husband's airplane project. She didn't elaborate as
to what his alternative activities might be. The
not-so-obvious possibilities are indeed endless. I guess I'll
have to categorize that statement as not belonging to the set
of simple-ideas pertaining to the OBAM aviation community.
I humbly stand corrected.
The simple idea of 'hobby' is not universally applicable . . .
but I think 'expensive' still is.

I posted a question about this a while back and got no response so I'll ask
smaller groups of questions instead.
I have an EIS engine monitor from Grand Rapids Technologies. It contains
all required info I need except current flow.
I'm also installing the single battery, dual alt using the SD-8. In your
opinion should I install 2 shunts and monitor the current at these spots?
What benefit does this provide me? If so I'll install a single ammeter and a
switch to go from main alt to stby alt.
The shunt on the main alt circuit indicates that it must be attached with 6
inches in length of less. Does this mean these shunts are typically
installed in the engine side of the firewall?
Thank you
BobR

Bob R.
Presumably you are aware of the Hall Effect current sensor that GRT
sells for $60.
If you really want to know the amps, that avoids having to install
shunts and if you so desire you can run the B-lead from both alternators
through it. I was not willing to install shunts but the hall effect
sensor is just a doughnut with about a 1" hole that you run a wire (or
several) through. There is no particular need to know the current
though. The voltage tells you what you need to know and the EIS gives
you high and low voltage warnings as well.

A possible solution to a 'skinny' wire and a bit too large terminal that
I've used for 30+ years is to double over the wire before inserting into
the terminal. Sometimes trimming a strand or two at the bend is
necessary. Using stranded wire is assumed. Earl

I tell my wife that I ought to be able to spend more on aircraft than
otherwise, since because I jumped directly from motorcycles to aircraft,
bypassing boats altogether, I saved us thousands and thousands of
dollars that ought by rights be applicable to planes.

This is the big one. I'm aware of two Glasairs that suffered
stuck starter contactors with a bypassed master relay . . . both
suffered battery damage and one hurt the starter.

Yup, all that 28-volt stuff is "aircraft" and therefore
low volume and blessed with more holy water than one usually
asks for. What's the 28v power requirement for the
Avidyne stuff. As you mentioned in your direct e-mail,
perhaps some boosters would be cost effective and let
you run a more generic 14v system.
Tell us more about the airplane . . . the mission and your
design goals.

Took a brand new Eveready Gold 9v out of the package
and tested it against the house brand 9v battery that
cost me 1/3rd as much. Here's the plots:

The red plot is the Eveready.
