Today's Battery Gripe

I asked about finding a AAAA battery holder a few weeks ago, because I
couldn't find one on the web. So I made a single AAAA cell holder out
of a piece of pc board and some spring clips.

I tore apart a couple 9V batteries and found that usually 5 out of the
6 AAAA cells inside were not dead, usually only one cell was bad and
caused the battery to fail.

I've been putting those halfway good cells in the battery holder and
running a V boost circuit to drive a white LED. I put one in the
holder and it might have a beginning voltage of 1.35 or so volts, and
I let it run until it is well below a volt, usually below .8V.

What gets me is the every single cell fails by the same process. The
top (negative) contact pops open and the cell leaks some juice, and of
course the contact doesn't make contact with the inside of the cell.

This means to me that every 9V battery will fail and leak juice inside
of the radio, usually corroding the contacts and doing other damage.
This is something that I feel shouldn't happen. The cells shouldn't
make a mess or do damage.

But every single cell has failed in this same way. Doesn't this seem
to be a defect that should not happen, or rarely happen? Has anyone
else verified this?

I cant even remember the last time a battery leaked in my household. I've
had 9V batteries in smoke detectors for many years, AAA and AA batteries in
remotes for years, and never a drop out of them. It must have something to
do with the fact that you have taken the batteries out of their casing.

Hi Watson,

I quit playing with the AAAA cells in the 9V batteries for this same
reason. I got tired of cleaning up the cell juice off of my bench and
tools.

The reason they don't blow when they are in the 9V cells is they have a
cardboard insulator on either side that squishes the cells tightly after
the 9V case is crimped. These AAAA cells are DEFINITELY not ment to
see the light of day!

Sounds like these AAAA cells are not ment for high current drain electronics. They probably have
very high internal impediance, which in turn generates enough heat to expand the cell. You may be
better off with the flat mini cells found in the Varta 9 volt rechargable battery. Some modelers use
these in 1/16 scale balsa models used in free flight.

Cheers

Sure they're contained. That doesn't seem to stop them from leaking.
The battery case soaks up some of the juice, but some still gets out.

I believe one was an Enercell (rat shack) and one was an Energizer.
But I threw away the casings since they were sharp, torn metal, so
that's from memory. The batteries are identical.

I had some RayoVac AA alcalines I bougt 2002 or early 2003, that
popped and leaked (i could hear them fizzling). Half luckily, they
were in my 4xAA holder I use to get a little 6V whenever I need it.
The one I heard pop, looked aroind to find one of them leaking (I was
repairing my laptop at the time, and thought I blew something in it at
first),

9v cells do NOT leak in normal use, there was a thread here some
months back. the concensious was that the outside case and inside
construction contained any spills.

i have never, ever, had one leak, the only type i can say that for.
most others said the same. --Loren

Hi Watson,

The interesting part is they pop open even if they are just
sitting, unmolested, on the bench. I had a string that I
removed from a 9V, and it was just sitting there. Every couple
of days another would pop.

It was interesting to see that the little carbon rod in the
center was snapped off in each case.

-Chuck, WA3UQV

Note, you can get into 9V batteries really easily if you go at them
from the bottom. Take a screwdriver, and push it under the folded
over metal edge of the can. It unfolds very easily, and the cells
can be removed by pressing the terminal end with your thumb.

This is something that I feel shouldn't happen. The cells shouldn't
make a mess or do damage.

But every single cell has failed in this same way. Doesn't this seem
to be a defect that should not happen, or rarely happen? Has anyone
else verified this?

It is in my experience the the cells in 9v batteries are very poorly sealed.
Whenever even the slightest stress is placed on them, they never pop, they
just start fizzling. Although only about twice have I had juice escape
from the outer casing.

Hi Watson,

I quit playing with the AAAA cells in the 9V batteries for this same
reason. I got tired of cleaning up the cell juice off of my bench and
tools.

The reason they don't blow when they are in the 9V cells is they have a
cardboard insulator on either side that squishes the cells tightly after
the 9V case is crimped. These AAAA cells are DEFINITELY not ment to
see the light of day!

I appreciate that you verified that I was not the only one having this
problem. Others doubted that it could happen. At least now they know
that two people have had this problem, and it's not just a fluke.

It's not a problem. These batteries are not meant to be dissasembled and
used a piece at a time.
In their original assembly they operate quite well.



Thanks.

I asked about finding a AAAA battery holder a few weeks ago, because I
couldn't find one on the web. So I made a single AAAA cell holder out
of a piece of pc board and some spring clips.

I tore apart a couple 9V batteries and found that usually 5 out of the
6 AAAA cells inside were not dead, usually only one cell was bad and
caused the battery to fail.

I've been putting those halfway good cells in the battery holder and
running a V boost circuit to drive a white LED. I put one in the
holder and it might have a beginning voltage of 1.35 or so volts, and
I let it run until it is well below a volt, usually below .8V.

What gets me is the every single cell fails by the same process. The
top (negative) contact pops open and the cell leaks some juice, and of
course the contact doesn't make contact with the inside of the cell.

This means to me that every 9V battery will fail and leak juice inside
of the radio, usually corroding the contacts and doing other damage.

I too come across the odd leaking alkaline. Does anyone know what to
nuetralize the leaked poop with? What about NiMh? For lead-acid
batteries it's obviously baking soda. ...Stepan

For alkaline it is vinegar.
 
A clue as to what the electrolyte is could be found in the
battery's name: Alkaline.

Funny thing about baking soda. It is neither an acid, nor a base.
It is what is known as a buffer. It likes to keep the pH of its
solution at a nice neutral 7.0. So, if you add baking soda to
an acid, it will release CO2 to neutralize the acid. If you add
it to a base, it will neutralize the base.

Close, but not quite. Although baking soda (sodium bicarbonate) is a
buffer, it is not perfectly neutral but instead a little noticeably on the
alkaline side.
