KR> Battery type

[Chris Prata]

I may as well chime in, ran an Odyssey PC625 in my Avid. It is a great, 
long-lasting durable battery.

Longer service life
With 3-10 years of service life, ODYSSEY batteries save consumers time, money, 
and aggravation.Longer cycle life
70%
 longer cycle life compared to conventional deep cycle batteries - up to
 400 cycles at 80% depth of discharge - high stable voltage for longer 
periods of time.Longer shelf life
Can
 be stored on open circuit (nothing connected to the terminals) without 
the need for recharging up to 2 years or 12.00V, whichever occurs first.Faster 
recharge
The highest recharge efficiency of any sealed lead battery on the market - 
capable of 100% recharge in 4 - 6 hours.2 Batteries in 1
combines
 in one box the characteristics of two separate batteries. It can deep 
cycle (be recharged) as well as provide enormous cranking power.Superior 
cranking
The
 5 second cranking power of Odyssey batteries is double to triple that 
of equally sized conventional batteries, even when the temperature is as
 low as -40?C (-40?F).Mounting flexibility
Non-spillable design - can be mounted on any side in any position except 
inverted.Vibration resistance
Design protects against high impact shock and mechanical vibration - a common 
cause of premature battery failure.Extreme temperature tolerance
Operating
 temperatures from -40?C (-40?F) to 45?C (113?F), for models without a 
metal jacket and from -40?C (-40?F) to 80?C (176?F) for models with a 
metal jacket.Totally maintenance free
No need to add water, ever! Drycell design with resealable venting 
system.Improved safety
US Department of Transportation classified as a 'non-spillable' battery. No 
acid spills, no escaping gases.

KR> Battery

[John Martindale]

Hi Mike

It's a permanent magnet alternator. It outputs a sine wave AC that is rectified 
to DC electronically by the regulator and then regulated to 14.8 volts. A 
generator puts out DC, the rectification is accomplished physically by the 
commutator and brushes within it. Your PMA won't deliver a charge at idle off a 
direct drive...it doesn't spin fast enough. If it were a field driven 
alternator then things would be different.

Here are the other Odyssey batteries.  If going the lead acid route one
of the slightly smaller and lighter ones would also be a good choice.

The Odyssey (PC680) is probably the very best choice in batteries for 
the KR. That's the battery I use in my 
KR. https://dl.dropboxusercontent.com/u/32133949/IMG_8083.jpg I 
question the reserve capacity of the LI-on and other types of Lithium 
batteries to carry the load if the alternator goes south. I will 
trust my little 4 AMP hour backup battery (seen just above the 
Odyssey in the photo) to be ready and able to keep my fuel pump(s) 
and other optional equipment running if and when I loose my 
electrical system. To me it's a known quantity. It happened once, 
the engine never sputtered, and I landed safely. I keep it charged 
while flying and can keep it charged with alternator output if I need 
to bring it on line.

I have a PC680 battery in my Mustang 2 and it is great and small.  It is
pretty much the standard RV battery.  They make smaller versions also. 
They are heavy though (not as heavy as most lead acid, but heavy none
the less).


If I was buying a new battery today I would get a LiFePo4 (Lithium Iron
Phosphate).  These are almost as light and high capacity as Lithium ion
and Lithium Polymer batteries, but they are much safer.  Li and LIPo
tend to explode or catch fire when abused so I do not recommend them,
but LiFePo4 are safe.


There are many Lithium iron phosphate batteries you can buy today, but
they need special balance chargers and other protection methods.  The
only ones I know of that have all of that already built into the battery
are from EarthEx. 
http://earthxmotorsports.com/product-category/experimental-aircraft



I have one of the small ETX12B batteries that I bought for my avionics
backup.  It is 1.3 pounds and can back up all I need for IFR for longer
than my engine can run on a tank of fuel.  I will be getting one of
their larger batteries for engine starting when my PC680 dies (which
from experience of others will not be for many years).

This thing was in unedited and unfinished form and got sent by dwarves
while I was sleeping.  Damn dwarves.  

So I'm cleaning it up just now and re-sending.  Please ignore the earlier
posting.  Dwarves did it.

One of Mark's pictures had a lithium battery in it and since batteries
have been on my mind lately I thought I would recount my experiences
lately.  I left off with the previous email the dwarves got ahold of
saying something about Ken Cottle having built my battery box on 335KC to
hold a garden tractor battery.  The reason for the bigger battery was
because when he built the plane the starters that were available were not
geared.  They were direct drive and needed a lot of amps - that's what he
told me about his reasons for using a larger battery.  Motorcycle-sized
batteries were the norm back then just as they are now for KR's.  As for
why he mounted it on the hat shelf, it wasn't for CG reasons as I
suspected but rather simply because there was no room for such a large
battery on the firewall.  

Having the larger-than-normal sized battery box has been a huge advantage
once I started adding electrical loads to the plane.  With the Diehl
alternator/generator (I've been calling it an alternator but somebody
just told me it's a generator because it uses magnets) not turning very
fast, the battery has to carry the load of all the things that are on at
night when coming in for landing with power at idle.  The secondary
ignition is 8 amps just by itself, at idle.  The two landing/taxi lights
are 50 watts each, the position lights draw a bunch of amps, plus
transponder, strobes, radio & linear amplifier, beacon, all the panel
stuff like GPS, instrument lights, fuel flow meter, etc.  I calculated
the load a long time ago and have it all noted in the logs but things
have changed so need to do that again, especially now that I'm putting a
new battery in.  It's time for a fresh evaluation of my primary
electrical system.  

I do have a secondary, back-up electrical system which (I thought) was
completely separate from my primary system.  I designed it that way but
somehow I've accidentally got them linked since the last time I turned
the secondary system on it engaged the solenoid on my primary system. 
Somehow along the way, over the years, I've connected something that
compromised the isolation of each system so that whole thing needs to be
re-thought and re-done and perhaps done away with entirely.  The
secondary system has it's own 20+ Ah battery that was intended just to
drive a fuel pump and the artificial horizon.  Since I put that system in
I have learned that the engine will run just fine with the Ellison on top
without any fuel pressure beyond siphon pressure.  Fuel level in the
header tank is below the level of the Ellison yet the engine will
continue to run with the fuel pumps turned off . . . so darned if I know
why it does.  I didn't think it would, which is why I put in the
secondary system.  As for driving the horizon, there are better solutions
available now than back when I put this electrical system together.  That
little Dynon D2 for instance.  You can just about replace the whole panel
with one of those and it'll run on its own built-in lithium-ion battery. 


Back when I was looking for the best battery I could find with the
dimensions of a garden tractor battery, I found only one that was
exceptional.  It was the battery for the Mazda Miata 1991-2005.  It was
AGM, 32 Ah with 400 CCA at 32?.  I think it was 2007 that I found that
battery at Powerstride, a company that has a location here in San Diego. 
I paid about $185.  The Miatas came from Japan with Panasonic AGM's
installed but those batteries are unavailable here in the U.S. so dealers
have been recommending one made by East Penn with pretty much the same
specs as the one I've mentioned above from Powerstride.  Since I bought
mine, other suppliers like East Penn have brought their products to
market so prices have dropped and variety has increased.  This "Miata
Battery" (which is how it is known and referred to in the battery world)
now comes in both AGM and flooded cell designs.  Length and width are
standard for this battery but height varies in some cases.  The battery I
bought in 2007 has been slowly failing over the last year or two causing
many and varied electrical gremlins.  It always took a full charge and
kept it so I haven't realized (until my trip to MMV and another trip to
Big Bear immediately following) my electrical problems have been due to
the battery.  I've been chasing grounds and and looking for other
possible sources of problems.  I almost sent my TruTrak artificial
horizon back to the shop since it was acting up intermittently but that
would have been $400 wasted so I'm glad I didn't.  When batteries start
failing the results are all over the place.  Very tricky. This will be
the second time a failing battery has fooled me into thinking I had
problems from sources other than the battery.  The other

Your alternator should be putting out at almost idle.. ?If not, it might be a 
regulator issue. ?Generators won't charge until the rpm.s increase to around 
1400/1500, but that should not be the case with an alternator.
I think you have a charging issue instead of a battery issue. ?Of course, when 
that goes on long enough, it will kill the battery.

KR> Battery Life

[Sid Wood]

The Power-Sonic Batteries PS-12180 NB 12 Volts 18 AH (main) and PS-1272 F2 
12 Volts 7.2 AH (backup) both died today in my KR-2.  Actually the backup 
probably died about 6 months ago; since it was never used by the system, I 
did not pay much attention.  Only had them for 4 years and 6 months.  From 
reading the Power-Sonic specs, I had thoroughly abused these batteries.  The 
instructions for maintenance called out storage temperature limits and float 
charging requirements to keep these batteries going for a full life up to 4 
years.
Not to fear, BatteryPlex.com has replacements in UPS shipping right now.

It is important to have the charge voltage (regulator if you are 
using one) be set to the proper level for the type of battery you are 
using.  A volt or two difference can be hard on a battery if it not 
correct for the battery type being charged.

I'd recommend a totally sealed battery if possible.  Looks like you 
will have a fairly heavy electrical load.  What alternator output, in 
amps, will you have.  Three position lamps, non LED's,can pull 3 to 6 
amps by themselves.  Just to throw out a ball park figure, I'd want 
at least a 20 AH battery and at least a 15 AMP alternator with your 
electrical load.  Like I said, that's ball park without doing any 
math on expected loads, etc..  You want enough excess alternator 
output to keep the battery charged.

 I have a Odyssey PC-680 cranking the 160 hp O-320 in my home built SuperCub. 
If it had fit without making major modifications, I would have converted the KR 
to the Odyssey battery as well. I've only had the Cub flying for a few months, 
but others using the Odyssey batteries in their RVs and GlasAirs have several 
years of use on their batteries, so apparently they do have at least a few 
years longevity.

had something that sounds just like this a couple years ago. all your

I too bought a new regulator. mine ended up being a bad crimp on one of my

or around the regulator. i have a GP VW 2180.

Hey guys,
Absolutly a perfect day today and I am sitting her typing. Tried to start 
N357CJ and the battery was dead, I thought that I had left a gps on or 
something so I just stuck the charger to it for 20 min. and triedd to crank it 
and she barly turned over. The battery was new in March but I thought I better 
take a closer look. When I looked at the battery I could see it was bulged out 
on 3 sides and when I got it out it actually had a blow out hole in the middle 
of a verticle corner on the groung end. I took it back to the battery warehouse 
nad they thought heat but couldn't be sure. They also said they were going to 
keep it as an example. I bought a new battery of a larger cranking amp size 
that they did not have before. I am gooing to check ground and power 
connections again and I may change the voltage regulator. I have the JD alt. 
and regulator.There has been no sign of over voltage as 14.1 is the highest I 
have seen and mostly 13.8 to 14.1. No popped breakers and cowl temps and engine 
temps have not gone where it should have affected a battery. Leave it to me to

KR> Battery type

[Paul & Karen Smith]

The major difference between aircraft and auto batteries is the plate
design.
(among other things like robust construction and longer shelf life) 

You see cars tend to do frequent starts and short recharge times (down the
corner
shop for a pint of milk) but don't need to run very long if the alternator
dies.
Airplanes start less frequently and generally run for a good while when they
do
but absolutely need the best life if the alternator fails.

In the July'09 Kitplanes this is described in detail.

Aircraft batteries have thick plates for sustained current draw (0.1") but
may
suffer in the cranking department. 
Auto batteries have larger, thinner plates (0.05") for massive cranking
current
but suffer in the long draw department

Therefore aircraft batteries have relatively higher Amp-Hour (AH) rating
Auto batteries have a relatively higher cranking current rating.

This is not to say not to use auto batteries but please understand the
benefits
and limitations. IFR or highly electric planes should really use an aircraft
battery
or at least have a backup (as I will be doing) Aircraft that use
predominantly
steam gauges, gravity fed fuel and magnetos can get away with an auto
battery.

KR> Battery type

[laser...@juno.com]

The next generation of battery technology after gel cell is AGM -
Absorbent Glass Mat.  It comes in all sizes so get the AGM with the
highest Ah rating that will fit your battery box.  Of the AGM batteries,
you want a "cranking" battery, as opposed to a golf cart or wheel chair
battery.  The Ah can be rated the same so if you just go by that you may
wind up with the wrong one.  I did it.  The two designs (cranking vs deep
cycle) have differences in the way the plates are engineered and placed
within the battery.  You can fairly quickly ruin a deep cycle battery by
using it as a cranking battery.

I get mine from Powerstride, which handles various brands in addition to
their own.  Their headquarters is in Corona, CA with branches around
California, including here in San Diego.  You may be able to find a
distributor such as Powerstride in your own neck of the woods and save
shipping, although since they all come from Asia these days the shipping
is going to get factored in at one point or another.  

Anyway, my newest AGM is a "Miata" battery ($160 list price), specially
for the Miata but is the same size as the lawn tractor battery box that I
have.  I need a really good battery since at night, with everything on
and a 20 AMP alternator putting out half that at lower RPM, I'm almost
completely dependent on my battery for short periods.  

An AGM cranking battery is what you want, with the most Cold Cranking
Amps for the size battery box you have.  

There's tons of battery info on the internet.  Do some looking.  And buy
one of those Harbor Freight bettery maintainers.  NOT a trickle charger,
but a float charger.  You can buy expensive ones but the HF ones seem to
work fine.

Well I found a place that says a reasonable current draw for a Sentra

better, and the added weight would be minimal over that short 5' distance.

I second or third that recommendation.  That's what I used on all my 
heavy cable (starter, engine ground) and it works great.  That also 
served well for twenty plus years on the Tripacer I had which had the

Now that winter has hit in force, I am looking at "improvements" to make.
One is to move the battery from just behind the seat to some more forward

the main spar. The reason for the move is poor starting performance. The
cables that I have from the battery to the firewall are evidently crappy and

KR> Battery crossover (isolator)

[mbz...@comcast.net]

I think you might have misunderstood me. I was talking about a crossover, or 
more commonly known as an isolator. 

There wouldn't be any mods to the dashboard. All an isolator does is isolates 
the batteries, so they are not "bank" 

charged. Just do a search on a battery isolator, and you will get many hits. It 
connects to the alternator (+) and from there 

goes to the batteries. Here is a link to the first of many hits. But I'm sure 
you can find much cheaper sources 
http://www.newmarpower.com/Battery_Isolator_Integrators/Battery_Isolator_Integrators.html
 

Also might look at the intergrator just below the isolator, its a different 
option, that does something similar. 

This was in response to your concern of one battery going dead, and dragging 
the other with it.

That's what they say, but I've flown mine at 12,000' on a regular basis, and 
even as high as 17,000.  I think what they may mean is that system 
robustness is degraded, for example it won't meet the same shock standards, 
but as smooth as it is at 17,000', mine still works fine.  Having said that, 
I have a plastic water bottle that I closed up tight at 12,000' or so, and 
once on the ground I'll bet it has about a third of the volume left in it.

On another matter, Harbor Freight sells a little 12V to 120V converter 
that's a little bigger than a soda can, and is good for several Amps. 
That's what I use, and it works fine except if I start the plane with it on 
and the laptop plugged in, it'll turn itself off out of self defense.  The 
cure is to always cycle the switch after starting the engine, and it hums 
away happily for the rest of the flight.  I also use it to charge my cell 
phone sometimes.

I'll see y'all on the other side...

nuthin. I left it on there a month, and returned it functioning like new. My
niece has a motorcycle shop. The mechanics never seem to have time to keep

Hi Oscar,

Yes it will make a trickle charger for any size battery.

I have salvaged several of the UPS units you are talking about. Generally
its not the batteries that go bad and you can put thoes small batteries on a
regular 12 volt charger and recharge them. Normally for me its been the
circut board that goes bad from power surges or whatever. Sometimes you will
find a small fuse soldered somewhere on the power supply board or power
supply side of the main board. If you can solder in a new fuse you might be
in business. 

These are not only a trickle charger for batteries but the supply from the
batteries is a 12 volt to 110 converter for the duplex outlets. I took one
of the units apart, disconnected the wires from the batteries and then
connected it back up to the battery in my truck. Leaving the circut boards
and 110 outlets intact. Made a great 110 converter for my truck. I have been
thinking this arrangement would also give me a really cheap way to put a 110
outlet on the panel or somewhere in the KR that I could plug in a laptop or
other type equipment if I needed to and the weight is small ounces.

One could certainly do that.  But why?  A quick look on line and I found wall 
wart type trickle chargers for as little as $16.  Then you have something that 
is sealed, electrically safe, and probably has a UL listing rather than using 
something in a way it wasn't intended to be used.

Take the UPS, replace the batteries in it, and use it to protect your new HD

Hi Oscar,

Yes it will make a trickle charger for any size battery.

I have salvaged several of the UPS units you are talking about. Generally its 
not the batteries that go bad and you can put thoes small batteries on a 
regular 12 volt charger and recharge them. Normally for me its been the circut 
board that goes bad from power surges or whatever. Sometimes you will find a 
small fuse soldered somewhere on the power supply board or power supply side of 
the main board. If you can solder in a new fuse you might be in business. 

These are not only a trickle charger for batteries but the supply from the 
batteries is a 12 volt to 110 converter for the duplex outlets. I took one of 
the units apart, disconnected the wires from the batteries and then connected 
it back up to the battery in my truck. Leaving the circut boards and 110 
outlets intact. Made a great 110 converter for my truck. I have been thinking 
this arrangement would also give me a really cheap way to put a 110 outlet on 
the panel or somewhere in the KR that I could plug in a laptop or other type 
equipment if I needed to and the weight is small ounces.

Generally, those will work for similar batteries. Smaller batteries 
would likely require the charge current be decreased, and larger ones, 
increased.  In the absence of any actual numbers, I  suspect those 
charge current ranges will overlap when the batteries are close in their 
ratings.

KR> Battery

[Joe H Horton]

Guys,
Just to put up a point of information, I am using a battery that
is a generic called a universal with dimensions of about 3" x 7" x 10"
and 450 cold cranking amps. The first one I replaced at 2 years old last
July during the annual. I replaced it for no real reason except $40
seemed like cheap insurance. The new one started showing signs of a
problem in December with somewhat less starting umphh. Last week during
our cold snap I could get it to turn the engine over even after charging
and engine preheating. I removed it today and took it to the battery
outlet and they put a load test to it and it failed at about 78% power.
The good side was that I got $17 dollars off for the warranty. The bad
side was I put it off knowing that something was going wrong and not
doing anything about it until I missed a flying day. Lesson is to take
care of problems as soon as they start not until they have a chance to
run their course.

KR> Battery placement

[Pond Family]

HI Gang
I've got enough of my home repairs completed I can once again turn
my attention to the little bird in the back yard. C-GGGW is a standard KR2
(6 gallon wing tank)with 350 hours on it using a hand prop 1835VW engine.
The original engine was tired and needed replacing before it my turn to fly
it.

As I wish to have the full Cadillac model I replaced the engine with an
1835VW with starter and alternator. 

I know the best time to set the ideal location for the battery is at the
airport but... If you were going to place a bet on the usual location for
the batter where would it be? For now I'll be using an affordable motorcycle
battery with the idea of one day replacing it with the ODYSSEY BATTERY

The only reason I'm asking now is get the wiring installed (with enough
slack).

[Willie van der Walt]

  I made a bracket and fitted the battery on the firewall ,on the engine 
side, in the middle between the engine mounting legs. The cables to the 
starter are heavy and so is the battery. To save weight I also used a bike 
battery and kept the cables as short as possible.

H.  My flight test doesn't match your flight test.  My battery is
mounted on the cabin side of the firewall, and I think yours is on the
engine side.  I inspected mine today, and it still looks perfectly new.  Of
course mine might explode at any minute.  Given that the engine side (on my
airplane anyway) is about 80 degrees hotter than the cabin side (not
counting radiation), I'd say I might have a bit of margin left in my case.
Thanks for establishing the upper limit for me though, Mark!  For now I
think I'm good to go, but might look into a regulator that's a little
smarter than the one I have now.

I basically stripped the whole top off of mine today, removing cowling,
forward deck/canopy, and aft deck, so I can do some overdue maintenance.
It's supposed to be crappy for the next few days, so it's a good time for
that sort of thing.  Little stuff like moving the static port (again),
adding a fuel totalizer, making the fuel system totally redundant, and
mounting the auxillary display to my panel for my laptop.  It brought out
all the hangar hounds from around the airport for a look.  "Field stripping"
makes maintenance pretty easy.  See

This is what happened to my battery also when the Kubota regulator failed
(refer archives), I think as a result of overreving the dynamo. The Kubota
dynamo revs should not exceed 4250. I then used a bigger pulley (about 4 1/2
inch dia) to slow it down and have had no further problems. I imagine the
Deere is similiar. Hey, it could be worse.at least your battery buffered

KR> battery had bulged

[Steve Jacobs]

might look into a regulator that's a little smarter than the one I have
now

+

Like most things, battery design has its compromises - electrolyte (gel)
volume, plate area, distance between plates etc.  These parameters
obviously effect size and weight for a given AH capacity and the often
ignored cold cranking capacity (where relevant).

Some batteries are designed to efficiently "store" energy that is
received and delivered at modest (charge / discharge) rates - units
designed for Solar and UPS applications generally fall in this category
and are very effective provided they are not subjected to high charge /
discharge rates.  The acceptable charge rate (in this case) is more of a
trickle charge, but certainly not much over C/10 and the acceptable
discharge rate is adequate to deliver the full (stored) capacity over a
period of time.

Whereas we can control the charge rate and solve most of the battery
damage type problems, cranking an engine is very demanding in terms of
current draw, if the battery is not designed for this, its life will be
short. 

Subjecting the battery to a higher (than spec) charge (or discharge?)
rate is more likely to cause damage from overheating, than high temps in
the general environment.

Now that looks more like a project airplane than a flying airplane.

KR> battery had bulged

[Al Hawkins]

I am using the Compufire Harley series regulator, it disconnects the
charging voltage when the battery is full.
It is not cheap at $83, but it works great.

55121 22 AMP 1981-1988 Black Finned 
Big Twin Case, OE P/N 74516-86

I now have 52 hours on the plane and my Panasonic 17 AH battery is still
working like new, the Panasonic battery can be used to start engines per
spec sheet.

Like most things, battery design has its compromises - electrolyte (gel)
volume, plate area, distance between plates etc.  These parameters
obviously effect size and weight for a given AH capacity and the often
ignored cold cranking capacity (where relevant).

Some batteries are designed to efficiently "store" energy that is
received and delivered at modest (charge / discharge) rates - units
designed for Solar and UPS applications generally fall in this category
and are very effective provided they are not subjected to high charge /
discharge rates.  The acceptable charge rate (in this case) is more of a
trickle charge, but certainly not much over C/10 and the acceptable
discharge rate is adequate to deliver the full (stored) capacity over a
period of time.

Whereas we can control the charge rate and solve most of the battery
damage type problems, cranking an engine is very demanding in terms of
current draw, if the battery is not designed for this, its life will be
short. 

Subjecting the battery to a higher (than spec) charge (or discharge?)
rate is more likely to cause damage from overheating, than high temps in
the general environment.

KR> Battery Mount

[Brian Kraut]

I checked with a marine canvas shop, but it was too expensive so I made it
myself.  I used Sunbrell canvas which is a good UV blocking marine canvas
and the materials were about $800.00.  I probably have about 20 hours labor
in the cover.  Other than the home economics class we had to take in junior
high 20 years ago I have no other sewing experience so it is pretty easy and
anyone can do it, or talk their wife into it.

At the time the difference between a hanger and a tie down here was about
$300 a month if you could even get a hanger so it was pretty much a no
brainer for me to keep it otside.

KR> Battery Mount

[Don Chisholm]

I'm an automotive upholsterer by trade and if you don't mind my
2 cents worth  my favorite material to use especially for canopy covers
is a material called Odyssey Soft Touch manufactured by MarChem Coated
Fabrics.Inc.. What it is is a light weight coated polyester that is waterproof
and breathable and has a synthetic felt backing so it's not prone to chaffing
plexi or paint and has a 5 year manufacturers guarantee. Sunbrella Also makes
 a felt backed material but is considerably more expensive than Odyssey
each material has it's plus's and minus's

NAH!  I Love it when they ramble on and on and on and onwith  an
inappropriate subject.  Adds a bit of mystery to the net.  I think Dan's

And, I really appreciate it when they don't delete the tail end. ;o)

Does anyone have a pic? Duh! Try this, they are scattered throughout, but if

quickly. Email to da...@alltel.net if you have any questions.

Congrats on running the engine. A major step to completion.

When I moved my battery (main battery) to the firewall, I started
to build a box/holder but found I didn't have room for anything
but what you see in the picture at the following address.  The
battery is setting on a small piece of 1/4" alum angle that is
fastened to the firewall. The front vertical piece has a small
alum angle on the bottom edge of the battery to keep it from
slipping upward.  There are three 1/4" bolts that hold the battery
to the firewall.  This is a rock solid mount and there is zero
movement of the battery.  175 hours and no problems.

http://www.krnet.org/mvn2004/040929139.jpg

My small backup battery, top battery in the picture, is mounted
in a similar fashion.

KR> Battery Mount

[jscott.pi...@juno.com]

Mine is done very much like Larry's upper battery.  It sits on a piece of
1/4" angle aluminum with a pair of long holddown bolts and a simple strap
to hold the battery tight against the firewall.  

I was told that with my battery sitting about 3 inches from the left
exhaust pipe, my battery wouldn't last a year.  The first one failed
after 4 1/2 years and 325 hours.  The second one is 4 years old with 210
hours behind it and still functions normally.

KR> Battery Mount

[Brian Kraut]

You can look at www.engalt.com/kr2.htm and click on engine.  I had a simple
aluminum sheet metal box with no sides and long bolts on the top.  This is
the way the plane was when I bought it and it worked fine.  It had some
insulation wrapped around the battery.

The one thing I would prefer to have if I was starting from scratch is an
enclosed box to contain the acid if the battery leaks.  You can buy cheap
bigger battery boxes at boat supply stores.  I assume that you can find
motorcycle size plastic battery boxes from motorcycle parts suppliers also.
Make sure that you also have some kind of strap to keep it from coming out
the top in negative G maneuvers.

 am interested as well. I do not have hangar space and my KR leaks a lot of 
water into it via the elevator junction. Had to drill drain holes in each
