I bought one brand new for the exact purpose that you intend, when I was building...and
replaced it with a brand new one for first flight. I have also since
gotten a second one from someone that is using a Concord instead....
I still have the old original one...
Shipping will be the bugger...where are you?
Zap me direct,

Strange. I just downloaded it fine. On Bobs Aeroelectric webpage, I went to:
Downloadable Reference Materials > Page per System Drawings > ACAD Symbols

Temporary server glitch maybe? That error message doesn't have anything to
do with your CAD program. It's a website/server thing, but I know all of

At 05:38 PM 3/22/2010, you wrote:
Thanks for the offer. I have two.
Good for you. Over the course of several seminars
my opening presentation was on DC power and the value
of knowing the numbers, I would query the class as
to how many folks did not possess at least one multi-meter
of reasonable accuracy (handy little analog
testers need not apply). Generally there were three
or four who would raise their hands.
I immediately handed out meters from Harbor Freight.
The cost was trivial and it helped me emphasize
very early in the class that having some grasp
on the "size of things" was pretty important to
successful implementation of recipes for success.
I will try to get some data on my next airport visit.
I will record some numbers and get back to you. Is there anything I
should be aware of,or a certain protocol, before proceeding?
Not a critical one . . . it's time consuming
to sit and watch the setup for the purpose
of plotting performance. Data points acquired are
pretty coarse. Just see what the "float" voltage
is after a couple of days. Then turn something on
to put drag a couple a.h. of energy out of the
battery. Hook the 1562 up and see if you can
catch a top-off voltage along with some sense
of time that it stays in the top-off mode.
Speaking of data acquisition systems. There are
dozens of new players in the data logging business.
Emacs!
This USB interface voltage logger can be reviewed
at:
http://www.microdaq.com/lascar/usb/el-usb-3.php
It has 0-30 volt input range, sample rates from
1 sec to 12 hours and a 1% overall accuracy.
I suspect it's resolution is much better than
1% and may be as great at 0.1% of full scale
(10 bits) so for more exacting work, one might
be able to characterize a given instrument for
better performance in analysis of the data.
At $75 its a pretty good value. Folks with a
curiosity about such things are encouraged
to investigate this market for themselves.
I've got several good tools for doing this task
but none that are so handy as this . . . I'll
probably decide that I just have to get one
pretty soon.
By the way, if any of you own one of those
West Mountain Radio battery analyzers
http://www.westmountainradio.com/CBA.htm
They can be pressed into service as a
useful data logger/plotter. This curve
was gathered with just such a device.
http://www.aeroelectric.com/Pictures/Curves/Battery_Tender_Recharge.pdf
You set the thing up to "test" a battery
with say a 10 milliampere "load" and
set the end-of-test voltage very low. You
have to fool it into thinking that you're
testing a real 7 or perhaps 8-cell battery
to get the upper end of the voltage plot
where you need it. Then hook it across the
system being monitored. It will dutifully
gather voltage data for days if needs be
and produce nice plots too at no extra charge.
Of course, this ties up a PC for the
duration of the test. I keep a number of
junker 'putes around for just this kind
of task.

Yeah, they may have a battery box that is intended for a 680. I find
batteries are like computers, manufacturers make them just different
enough in size that you need to buy their battery box instead of the
competitors.
BTW - I'm going to fly soon, so if someone wants me to save my used (2
years) 680 battery for them (you pay freight from N57), let me know. Can
ship in May. If not I'll bury it in the back yard with the others (just
kidding).

Sorry, I included the word "situation" in the wrong location of my sentence.
Let me re-state.
I soon be in a situation desiring a used battery (PC680), to accurately
fabricate a battery box and associated cabling. It doesn't have to have any
life left in it.
May or June would be about right. I'll pay shipping if it's not too much.

You can find battery dimensions on the internet. Make the box a quarter
inch larger in both dimensions and 1 inch shorter so you can install your
hold down clamp. If you feel the need, shim the box with cardboard.

RG batteries do not benefit from being enclosed in
the classic battery box. The first batteries to
go aboard airplanes were somewhat 'infantile'. They
burp and gurgle. The liquid and gaseous emissions
were decidedly unfriendly to the insides of airplanes.
Hence, batteries were fitted with special caps. Battery
boxes were reasonably sealed and vented to the outside.
The recombinant gas battery is incapable of dumping
any liquids. Further, what ever out-gassing occurs
is low volume and quite dry. This means that airplanes
can now treat the battery as if it were a 17# chunk
of baggage. Secure it to a shallow tray with sufficient
strength to hold it down under say 10G of acceleration
and you're done.
See:
http://aeroelectric.com/Pictures/Batteries/Battery_Install_OBrien_1.jpg
The neat thing is that when major structure is a simple
tray, it's easy to change the size to accommodate future
retrofits.

Jared,
I bought my Odessey PC680 in Dec 06 and flew the first time in Jun 09.
The battery has done fine. I spins my IO-390 with no problem. I don't think
you will have a problem even if you buy a new one to use for the next 2
years. I'm going to replace mine with a new one in June and then every other
year afterward.
If you can wait until June, I'll send you mine for $14.69 plus hazard
shipping.

I'm still in the building stage, and I plan to use a PC680 battery in my
project. It seems wasteful for me to buy a new one just for the sake of
building my electrical system and battery support structure, since it will
be a couple of years before I'm ready to fly. By then I would like to
start
my flight testing with a new battery, so it makes good sense to make use of
a retired one for such construction ground operations. Is there is anyone
out there who has proactively removed a PC680 and would like to sell it to
me? I know that some people have mentioned that they use them for lawn
mowers and such, but surely there is someone out there who has one sitting
around. If you are that someone, please send me an email with your
requested price and payment method.

Look at your local computer parts/electrical supply store for a PC680
lookalike. Or search the internet for PC680 knockoffs. The ones I have
found are black versus orange, but have the same technical specs at
the PC680 and are the same size and shape. They run around $40 or
less. I'm not sure I would want it in a flying airplane, but they work
great for other purposes. I have one on an electric gate and its been
working for nearly ten years with a Battery Tender Junior charging it.
