More on batteries

Post by Walter Klatt » Fri Feb 17, 2012 8:27 pm

I visited my local Canadian Tire today to check out their battery
selection, and found another potential candidate. Previously, Bob P. had
suggested using their model 12N14-3A motorcycle battery. It has 128 CCA
(cold cranking amps) with a reserve capacity of 12 minutes. Weight is
only 7.5 # dry, with 27 oz acid for an all up weight of only 9.2 #. Reg
price was 49.95.

While there, I checked out the rest of their stock and found another
one, that was the same size as this one, but a high performance version.
It is model YB14L-A2 and has a whopping 190 CCA and 17 minutes of
reserve capacity. It weighs .1 # more, for an all up weight of 9.3 #,
still well under 10 pounds. Reg price is 59.95.

My current 24 pound Concorde battery has 215 CCA but a reserve capacity
of 50 minutes. It has no trouble at all with starting my 150 HP O320
Lycoming using a Skytec starter.

For comparison, the Odyssey Drycell PC625 has 265 CCA and a reserve
capacity of 27 minutes. Weight is 13.2 #. Don't have a CDN $ price yet,
but would guess in the 130 - 150 range. Clearly, the quality of this one
is superior.

I would be interested in anyone's opinion whether the 9.3 pound CT
motorcycle battery would do the job. When I look at it, I still find it
hard to believe that such a puny little thing could start a 320 cubic
inch engine. Also, whether it would stand up to the heat and vibration
forward of the firewall.

However, saving pounds 14 pounds ahead of the firewall would really help
my C of G, which is a major consideration in my case.

Thanks, Wayne, for the additional info. If we're getting into the 16 # range, then I
would prefer the 13.2 # Odyssey PC625. Otherwise, I still would like to try the YB14L-A2
model at 190 CCA and 9.5 # if it works for the O320.

I was looking at the Yuasa web site, (manufacturer of the CT batteries), and the 12N14-3A
at 128 CCA is their "conventional" line, while YB14L-A2 is for "special demand" use.

Also, am wondering if my Chevy Sprint alternator (35 amp Nippon Denso) with its built in
regulator might overcharge and fry the smaller motorcycle batteries.

Batteries. These are basically the same size (just slightly smaller) as a

higher one (I think $59.99 or $69.99 each Cdn). I laughed at them at first,
but when we were getting all of our UTVA 66's ready to roll, the AME bought
36 of them for the 18 aircraft! The UTVA has a 24 volt system so we joined 2
in series and they just fit inside original slide out battery box (compared
to the "certified" $450.00 - 24 volt battery for the box). They crank over
the 340 H.P. geared/supercharged GSO-480 Lycoming engines (with 8 foot
diameter Hartzell 3 blade props) no problem and with a pressure carb it can
sometimes take awhile to get them running. They have never gone dead and
even after being left in the aircraft (outside in the winter) over a 6 month
storage period they still fire them up in the spring without a boost! I'm
sure one of them would throw the O-320 over just fine, at less than half the
cost of a Gill - 25 (but I know that you are looking for a bigger weight
improvement!).

As for the 12N14-3A, we found it wasn't even satisfactory for the 912 Rotax
in the Rebel AULA, unless you get it to hit right off the bat! We installed
an electric fuel pump on it to aid in the start, as the 912 can be a real
bitch to get going if the fuel has evaporated from the carb after a long sit
or it is frosty outside. The battery will be dead before the mechanical fuel
pump will get her going!

Walter,

You should be just fine with that YB14L-A2 - Tobey Riley used
the 12N14-3A in his Rebel, with a lightweight B&C starter, and it
would spin the O-235-L2C fast enough to taxi with !! And it still
worked well after 2 winters of storage ... I believe there's
at least one O-320 nearby that also uses this battery. The new
lightweight geared starters make a BIG difference ! And there's
NO problem with the alternators ...

We have been using 12N14-3A's in the 912 Rebel since new - still
on the third one, in 10 years ! They get down a bit after 3 years
or so, but are pretty inexpensive. The secret to starting ANY
aircraft is to pull the engine through at least 8 blades during
preflight, after priming. This was standard procedure when I learned
to fly, in the '50's - you get to check compression on all cylinders,
and suck in a good mixture, so the engine's ready to start on the
first blade with the starter. This is good for the engine, battery,
and especially the starter ! Of course, you have to be careful
swinging the prop - treat it like it's LIVE - 'cause it just MIGHT BE !!

After about 5 blades, the 912 shows 5 lb. of fuel pressure,
and a few pumps of the throttle will meter in enough gas to make
starting pretty easy - with the use of choke.... I can almost
visualize the solder dripping out of the starter if you just cranked
it without doing this !

Thanks for the tip on the "YB" models - I'll have a look at
that if I fly right through a winter again ! Of course, you don't
HAVE winter out there !! :-) (just jealous ...)

Thanks, Bob, I was hoping to hear that from someone. I think I might just try the
YB14L-A2. The low weight and price makes it very tempting.

My fall back is the Odyssey PC625, which I can get for 125 C$ at Polar Battery here in
Vancouver.

And yup, was up on Sunday, short sleeves, and had to open up the windows immediately on
landing, as it was too hot in there, with the sun beating in.

Walter I'm using a can tire battery thats for a jet ski the part # is
Y50-N18L-A It's a manifold vented battery and it will not spill. It turns
my 0-290 with a toyota starter very easily I haven't been able to kill it
yet even on the coldest days last winter. I'm using a nippon denso
alternator as well and it works fine with this set up.

the 340 H.P. geared/supercharged GSO-480 Lycoming engines (with 8 foot
diameter Hartzell 3 blade props) no problem and with a pressure carb it can
sometimes take awhile to get them running. They have never gone dead and
even after being left in the aircraft (outside in the winter) over a 6
month
storage period they still fire them up in the spring without a boost! I'm
sure one of them would throw the O-320 over just fine, at less than half
the
cost of a Gill - 25 (but I know that you are looking for a bigger weight
improvement!).

As for the 12N14-3A, we found it wasn't even satisfactory for the 912 Rotax
in the Rebel AULA, unless you get it to hit right off the bat! We installed
an electric fuel pump on it to aid in the start, as the 912 can be a real
bitch to get going if the fuel has evaporated from the carb after a long
sit
or it is frosty outside. The battery will be dead before the mechanical
fuel
pump will get her going!

I visited my local Canadian Tire today to check out their battery
selection, and found another potential candidate. Previously, Bob P. had
suggested using their model 12N14-3A motorcycle battery. It has 128 CCA
(cold cranking amps) with a reserve capacity of 12 minutes. Weight is
only 7.5 # dry, with 27 oz acid for an all up weight of only 9.2 #. Reg
price was 49.95.

While there, I checked out the rest of their stock and found another
one, that was the same size as this one, but a high performance version.
It is model YB14L-A2 and has a whopping 190 CCA and 17 minutes of
reserve capacity. It weighs .1 # more, for an all up weight of 9.3 #,
still well under 10 pounds. Reg price is 59.95.

My current 24 pound Concorde battery has 215 CCA but a reserve capacity
of 50 minutes. It has no trouble at all with starting my 150 HP O320
Lycoming using a Skytec starter.

For comparison, the Odyssey Drycell PC625 has 265 CCA and a reserve
capacity of 27 minutes. Weight is 13.2 #. Don't have a CDN $ price yet,
but would guess in the 130 - 150 range. Clearly, the quality of this one
is superior.

I would be interested in anyone's opinion whether the 9.3 pound CT
motorcycle battery would do the job. When I look at it, I still find it
hard to believe that such a puny little thing could start a 320 cubic
inch engine. Also, whether it would stand up to the heat and vibration
forward of the firewall.

However, saving pounds 14 pounds ahead of the firewall would really help
my C of G, which is a major consideration in my case.

Hi, Drew. I just looked up your battery on the Yuasa site, and it looks pretty
substantial. It has 260 CCA and weighs 14.3 pounds.

Thanks for the info. It's useful to know what others are using and their experience
before deciding which one to go with.

Didn't know you could use a Toyota starter with a Lycoming. Must be a lot cheaper than a
Skytec.

Walter I'm using a can tire battery thats for a jet ski the part # is
Y50-N18L-A It's a manifold vented battery and it will not spill. It turns
my 0-290 with a toyota starter very easily I haven't been able to kill it
yet even on the coldest days last winter. I'm using a nippon denso
alternator as well and it works fine with this set up.

Thanks, Wayne, for the additional info. If we're getting into the 16 #
range, then I
would prefer the 13.2 # Odyssey PC625. Otherwise, I still would like to
try the YB14L-A2
model at 190 CCA and 9.5 # if it works for the O320.

I was looking at the Yuasa web site, (manufacturer of the CT batteries),
and the 12N14-3A
at 128 CCA is their "conventional" line, while YB14L-A2 is for "special
demand" use.
Also, am wondering if my Chevy Sprint alternator (35 amp Nippon Denso)
with its built in
regulator might overcharge and fry the smaller motorcycle batteries.

Walter, another option, even still, at Canadian Tire is their Lawn Tractor
Batteries. These are basically the same size (just slightly smaller) as a
Gill (or Concord) -25 size battery, but weigh about 8 lbs less at
approx. 16
or 17 lbs. They come in two cranking capacities with it best to use the
higher one (I think $59.99 or $69.99 each Cdn). I laughed at them at first,
but when we were getting all of our UTVA 66's ready to roll, the AME bought
36 of them for the 18 aircraft! The UTVA has a 24 volt system so we
joined 2

Yes it was $35 from the auto wreckers. I had to make a bracket out of 3/8"
aluminum angle to mount it as the bolt holes on the toyota starter are on
the end. The whole unit weighs 9lb.

Dave I looked for the plans I used but couldn't find them so I'll wing it
from memory as best I can. The plans came from hints for homebuilders in an
old EAA experimenter so maybe your local chapter can help you. As I
remember you have to count the teeth on your ring gear if it's about 120
you can use any toyota starter with 9 teeth and if it's about 140 you need
a starter with 11 teeth all the toyota starters are pretty much the same
and are almost universally exchangable. The other nice thing about the
toyota is the gear is cantilevered so you don't need to put a bump in your
nosebowl.
