| Subject: | Re: duracell battery leak |
I had a 3 cell Mag Light with Duracells in it. Following the marketing
hype I always thought they were the best so I bought them in large
packages. Being a plumber I used it on a fairly regular basis and I
noticed that I had to bump it sometimes to make it turn on. One day
when it wouldn't turn on at all so I pulled the cap and found that the
batteries had leaked inside and corroded the whole interior which made
them impossible to remove. I ended up having the throw it in the bin.
No, I didn't leave it on or leave it stored with dead batteries. This
wasn't the first time I had an experience with leaking Duracells.
Having heard about this previously I decided at that moment that the
best fix for me was to discontinue all use of Duracells and let others
know of my problem with them. If enough folks stop using them they'll
soon fix the problem...in the form of "new and improved ultra..."

" If you have an electrically dependent engine then
perhaps your plans should include a second alternator
capable of supporting the engine . . ."I'm working on it. The
available vacumn pad on my Franklin turns at about 0.8:1 so the B&C 20
amp aux alternator won't put out enough juice below 2400 eng rpm to keep
my E-bus alive. The B&C "stack 'o pancakes" 30 amp model for
Continentals has some promise of fitting in a fuel pump drive hole on
the accessory case.Even without a spare alternator, I'm VFR comfortable
with the triple redundancy of an alternator and two batteriesto keep the
fires lit.

Understand . . . let's strive to base your 'comfort'
on knowing as much about watt-seconds in the batteries
as you have gallons in the tanks.

| Subject: | Re: duracell battery leak |
A few years ago I did a study of variability in various
brands of alkaline batteries. I concluded from the study
that there is no extra value to be realized for the
purchase of batteries that have high-dollar advertising
budgets. See:
http://www.aeroelectric.com/articles/AA_Bat_Test.pdf
I suspect that any brand and any size of alkaline cell
is capable of leaking under some conditions. Further,
given today's business environment for farming out
the production about any kind of product, there's
not much you can hang a hat on for stating that
brand D's demonstrable leakage problems will go away
if one moves their loyalty to brand E.
If you dig around in my alkaline cell stock that
ranges from AAAA to D cells, you'll find a host of
different brands. I've not suffered a severe battery
leakage event in so long I don't recall the last time.
At the same time, we go through batteries pretty
quickly. No cell sits around in a seldom used
device.
The fact that some of us here on the
list have suffered a leakage event with a particular
brand is not a definitive study of the propensity
of that brand for failure. If say 90% of all cells
presently occupying the battery box of our favorite
accessories are Duracells . . . it's axiomatic that
the propensity of any failures will be in Duracells.

Bob,
Now you've got me thinking Z-14. If I go with another alternator, I'm
one contactor away from Z-14.
One thing that is vexing to me is that I'm using Honeywell AML 34
switches because the aesthetics appeal to me. Problem is that they are
only available as DPST. I haven't thought about this too much, but I'm
assuming that I can accomplish the switching functions shown in Z-14
and other architectures with the Honeywell switches, but I'll just have
to use more of them and some behind-the-panel circuitry??? I can see the
S-700-2-5 being replaced with an AML 34 and a pusbutton switch. But what
combination would I use to achieve the function of S-700-2-10? In other
architectures I see this switch associated with some automatic function
that I don't understand.

Deke,
Sorry that you had to toss the 3-cell Mag Light. I would have made a
suggestion to try and save it. I had a 5-cell do that and with
Duracell's. At first I thought about sending the whole mess to Duracell
as they probably would have replaced the mag light. But, decided to see
if I could fix it. Using penetrating oil to soak the cell sides I was
able to tap out the bad cells with a dowel and light hammer work.
Amazingly, the mag light is made pretty well and it cleaned up just fine
with baking soda and oil. Now, I check the flashlight from time to time
as it is my emergency light for the car and gets little use.
David

That is similar to my experiences with Duracell. For more than a decade
I used them in my car and boat flashlights and had no problems. More
recently I have had several leak. Same environment and use profile,
many more failures. Anecdotal evidence, but enough to send me in search
of a different battery.
