Thanks, as I said you can turn the battery chargers off on all Boeing jets. I don't
know the specifics of the case because I did not look it up, sorry, but from
the description this is one of those gotchas.

They don't. It was a typo, 747-400. Sorry my bad; I taught it from 1989-1993.
Haven't been in one since. This model did have an inadvertent battery charger
shut down as I mentioned. It's just not something that's suppose to happen, if
the crew is paying attention, but stuff does happen.

I've not had anyone's alkaline batteries leak on
me in many years including Duracells. That's not
to argue with anyone's experiences . . . only to

deplete them totally and see if they leak at some
later time.
In the mean time, Duracell offers to repair or
replace a damaged appliance in their sales literature

Now it may be that they could claim no fault if
somehow their analysis says the cell was left

perhaps the auto off feature isn't working, etc.

Duracells are manufactured in Lancaster SC and Cleveland Tennessee.
The Goo is comprised of Sodium Hydroxide, Manganese dioxide, Mercury and a secret
Brew inside a steel can. They will usually not leak until the Manganese dioxide
shell is depleted then the steel can is oxidized by th "goo"
Duracell will replace any item that is damaged by a leaking battery. For low dollar
items it is no questions asked, for a big ticket item they will probably
want to see the battery to make sure it isn't 20 years old.
Best thing to clean with is vinegar rinse with water.

I do not know if they still do but Duracell used to make the Ray o Vac alkaline
batteries. Ran them down the same assembly line just put a different cover on
them.
If you are buying them in bulk from Costco you might want to check the dates they
could be really old.

Battery story--I posted some years ago my tale of using a 12V lantern battery drycell
to power my Telex intercom. When I rented airplanes I would use it, since
the small battery that came with the Telex was always going flat and the Cessnae
I rented often had no cigar-lighter power.
The first big lantern battery died in just a couple hours. I assumed it had been
used and returned to the store by a dishonest customer....But the replacement
battery was SMOKING when I landed and was so hot I had to remove it from my
flight bag by its attachment wires. I put in on the asphalt and it left a melted
mark. How close to a disaster I was, I shall never know.
I assumed the internal cells had crushed from the change in altitude, but I left
it in a metal trash can and never had it dissected.

Alkaline batteries (Duracells) are a base (same as baking soda) only much stronger.
As such a weak acid ie vinegar or lemon juice should be used for cleaning/neutralizing.

I'm not going to address the whole avionics master switch issue. What concerns
me is what sounds like a limited life on the Dynon internal battery.
I've heard stories of people getting them, taking them out of the box or testing
them during the building process and then not turning them off properly and
when the plane's power is disconnected they think there is a power outage and
just drain the internal battery.

Interesting hypothesis. I have a small
altitude chamber that fits into my temperature
chamber to do temperature/altitude combination
stress on small articles. Next time we get it
out and set up, I'll do some bashing on AA and
F-cells to see if I can precipitate a failure.

Yeah, I wonder if your Dynon battery was fully charged prior to this exercise.
On a typical Jabiru start with a charged main battery, my Dynon D180 does not
even see low enough main voltage to go on the internal battery. This is mainly
due to the rapidity with which the Jabiru normally starts. Now that it is
cold, and I did not richen up my idle mixture screw, it took me about 6 cranks
to get started the other day. Towards the end, my Dynon told me that it was
going on internal battery during the cranks. Even without an internal battery,
Dynon emphatically says that it is no problem to have it hooked live to the
main bus during cranking.
Good luck,

Good Afternoon Bob,
Just as a datapoint, I had a D sized DuraCell leak in a four cell Mag Lite.
I sent the unit to the company as directed by their website. They sent me a
check which covered the price of a new four cell MagLite and my shipping
expenses. I would still like it better if the cells never leaked, but the warranty
was honored. I do not have any idea whether or not the battery was beyond
it's 'use before' date as it was stuck so hard in the flashlight, that I
couldn't get it out!

Subject: | Re: Duracell Leaking Batteries |
FWIW, today I found one unused Duracell MN1300 battery within a package
of 12(with a "Guaranteed fresh through 2008" label) was leaking and
showed 0.1 volt open circuit. The remaining other two in the package
were clean and measured an open circuit voltage of 1.515. These are
marked as manufactured in USA in 2001, Bethel, CT 06801.
The Guarantee on the package says "Should any device be damaged due to a
battery defect, we will repair or replace it if sent with the batteries,
postage paid to Duracell Consumer Dept" followed by the address in
Bethel, CT.
Five years ago, I complied with the ACK Technologies Inc. Model E-01 ELT
product warranty statement that use of any other batteries than DURACELL
would VOID the WARRANTY and be in VIOLATION of the requirements of
TSO-91a OR FAR 91.52.
On the first annual inspection thereafter there were two of the
Duracells with significant leakage that had severly corroded the
electrical contacts in the unit. These batteries were only one year into
their multi-year life as printed on the batteries. ALL of the batteries
in the ELT still measured above 1.5 volts open circuit and the ELT
produced normal signal strength during the short-test performance check
prior to finding the corrosion/leakage.
It appears that leakage/corrosion of DURACELLS can happen while never
being removed from their original package during their Guaranteed-Fresh-
Dated-Life, as well as when they are installed fresh from manufacture,
in a device that essentially places no load on them throughout less than
a year, after which they are still capable of the same "like-new"
performance as the other cells in the same installation which did NOT
leak.

Subject: | Dynon EFIS & EMS power on the main bus |
My Dynon cable has 3 power leads which I assume is done in an effort to
alleviate this issue. Cable is from http://approachfaststack.com/
1. Main bus (DC primary power switch)
2. Essential bus (or alternate backup source)
3. Battery bus (or always on connection)
I have not experienced this behavior. If I start the Dynon while sitting
with the power off, I get the message, but If I add ship power I do not
get another message that it is on ship power. By pressing any button
then Next->Next->Info you can monitor the battery charge and the ships
battery level.
Did you connect the always on lead to your battery bus?

The spirit and intent of avionics master switch
was to "protect sensitive avionics from hazardous
spikes generated during engine cranking."
In years since, it has been discovered that while
there was significant brown-out during the first
few milliseconds of starter operation similar to
that shown here:
http://www.aeroelectric.com/Pictures/Curves/99_Saturn_SL1_2.gif
there were no high-voltage excursions that could
not be easily handled by simple components in the
potential victim's power input conditioning.
Further, the industry tapped a huge experience base
by forming RTCA and inviting all interested parties
in aviation to participate in quantifying and documenting
the magnitude and type of stresses a piece of avionics
should shrug off.
Based on our current knowledge and skill in crafting
airplanes and their accessories, there is no need
for an avionics master switch to "protect" anything.
I believe you stated that all batteries involved in
your test were of questionable condition either by
reason of age or state of charge. I'll suggest
then that what you experienced was not worthy
of generating concerns. You need to repeat the
experiment with a known-good ship's battery and
fully charged stand-by batteries.
It's doubtful that anything was damaged. Everything
you observed appears to be the byproduct of soggy
batteries.

According to the current Duracell website all mercury has been removed
from their batteries and they are now safe to dispose of in household
garbage without the risk of environmental contamination. (So they say !)
Maybe the changes necessitated by the removal of the mercury is why
these leaks are starting to turn up?? Quite a few things these days have
been modified from their original composition to the detriment of
function and for betterment of the environment.

For low dollar items it is no questions asked, for a big ticket item
they will probably want to see the battery to make sure it isn't 20
years old.

Subject: | Re: Duracell Leaking Batteries |
I am going to guess it is a QC problem in the factory.
I was an engineer for them in the mid 70s and we had a really tough time with new
automated equipment in preventing "leakers". Problem was so bad at one plant
we almost had to shut it down. They (Duracell/Mallory Battery) really took the
problem of leaking batteries seriously. I am really shocked to read this thread.
As you say things change and not always for the better.

Yes, including the glue that holds the foam on the external tank of the
