Jabiru 2200 cold starting

[herman pahls]

I have an ea
Jabiru 2200 80hp in my kitfox.
Recently it refuses to start the 1st start of the day without jumping to the car.
This part of Oregon does not get very cold. 50 degrees F.
Once it has run a few minutes it will start the rest of the day immediately.
I am using a 4 year old Oddysey PC 625.
I also tried another 4 year old Oddysey PC 625 that I use in a motorcycle powered car with the same results. Starts the car great.
Before I buy another battery I would like to ask this forum what life are members getting out of Oddysey's and is the PC 625 still a good choice for the Jabiru 2200 80 hp.

Hello,

This battery works on my kitfox, checked, it's 200 CCA: Xtreme Powersports BATTERY Xtreme AGM Permaseal XTAX14-BS

$69 plus $12 shipping on the big auction site. Chinese battery. The Xtreme 2 is $99 and made in the USA.

SIZE: 5 15/16"L * 3 7/16"W * 5 3/4"D Item number: XTAX14-BS
Weight: 12.1500 lbs
Voltage: 12V
Capacity: 12AH
CCA: 200
Primary Applications: Powersport
Replaces: 02420500, 12V14B, 44017, 6594800, 7401886, BTX14BS, CTX14BS, CYL14BS, ES14BS, ETX14, ETX14BS, FAYTX14, GTX14BS, KMX14BS, M3RH4S, SC14FA, YTX14, YTX14BS, YUEM3RH4S




On a Lycoming/Pitts w/ only 8 Amp Alternator and maybe 2-3 30 minute flights per week, the Odyssey would only last 2 seasons, then drift out the third year.

Once I started using a decent trickle charger, it lasted 4 + years.

I just grabbed a battery minder 12248 charger/desulfator. Might want to try the $40 version for a while to see if it saves the batteries at all. The $40 version isn't much for actually charging, just maint. 12118 or so is the model #, push the button on the green light to run desulfation...

The Odyssey likes 14.2 volts. My Kitfox's Rotax 912 seems to put out 13.8 volts. That and short flights will kill a battery w/o trickle/maint charging.

I use a generic ATV 12V 12AH 150 CCA battery, has been fine down to 28 degrees for starting a 80 HP 912 UL.

I imagine it's the same for a Jab and Odyssey. Aged battery w/ some sulfation losing it's cold cranking amps- even at 50 degrees.

No maint/trickle charging, 4 years would be tough to expect the battery to have much oomph. Cars start easier than airplanes, in my experience.

Thanks for response.
After 4 years the Odyssey PC 625 may be used up especially for Jabiru.
I am surprized that a generic ATV battery of only 150 CCA starts the 912.
How many cubic centimeters is a 912?
The Odyssey PC 625 battery specs. are CCA 265A 9 (cold cranking amps??) MCA 350A
PHCA 625A
What does MCA and PHCA stand for?
Thanks for battery maintainance info.
Thanks Herman

Herman,

The info below comes from the Odyssey Battery website - http://www.odysseybatteriesonline.co...her/faqs.php#1


MCA stands for MCA stands for the "marine cranking ampere". It refers to the number of amperes a battery can support for 30 seconds at 32°F - whereas CCA is measured at 0°F.

Pulse hot cranking amp (PHCA - 80°F) rating does not have an “official” definition. The PHCA, a short duration (about 3-5 seconds) high rate discharge, is a more realistic measurement.

I have ordered a new PC 625 since the previous 625 was 4 years old and I did not use a battery maintainer which I have been told will significantly extend battery life.
I have an older Jabiru 80 Hp 2200 with a 1KW starter.
The newer 1.5 KW starters sell for approx. $500.
Has anyone switched from the 1 to 1.5 KW Jabiru starter and have comments regarding the outcome.
Thanks Herman

Herman, 200 CCA, not 150: I edited my post below w/ the info.

Rotax 912 UL is not very high compression:
73.91cu.in. / 1211.2cm³ Compression ratio 9.0:1

I have a 2200 Jabiru engine in my Avid MK IV and use a 360 CCA lawn tractor battery in it. Battery weighs 17.5 lbs and starts the engine with no problems up here in northern Mn. (we had -32F last night) Of course I preheat the engine in the winter before starting and fly in temps down to about 0 F. I've flown 16 different days since Dec. 4. Battery cost was about $35. It works for me. The battery in my lawn tractor is the same size, and it still works fine and it's at least 6 years old. Never do anything with it in the winter either but leave it sit. Take care,

Tried a new Odyssey 625 and I still have inconsistant starting the 1st start of the day without jumping to another battery on my Jabiru 2200.
If I use a battery maintainer I get better results but not consistant.
How do I plug in a battery maintainer at back country strips? So I need to solve this problem.
Ran a #4 ground wire from battery to starter housing instead of using the frame of Kitfox for ground. No improvement.
I have been told to move the battery to the firewall instead of behind the seat to shorten the cables.
Here are my questions.
How do I know if master and starter relays are passing full current?
Has anybody tried a fuel primer on Jabiru or 912's instead of relying on the Bing enrichener system to get fuel to the clylinders faster?
Does primer help cold starts more so than bing enrichener?
If so where and how would you plumb the intake system or Bing carb.
Thanks Herman

Herman,
I have both the Bing enricheners and primer on my 912. There are times during cold weather when 3 pumps on the primer makes a big difference in starting.

Do you mind telling me where on the 912 Bings the primer fuel is injected.
Do the bings have a fitting or do you need to insert one for the primer?
Thanks Herman
