Well, here is one for the books. No damage done, but about as strange as
it gets. I was up late tonight using the computer with my logitech
wireless mouse. I hear this snap noise, and this sputtering hissing
noise. I went to grab electrical cords thinking a Power supply let loose
in something. I could not find the offender but kept listening.
The noise was coming from the wireless mouse! It still had the LED
showing on the bottom, but it was flickering some. I thought to my self,
how and the hell could a mouse with two AA batteries make a noise like
that? Well, took the battery cover off. closer inspection showed that
one of the duracell procell battery's had Grey goo hissing out of the
positive end of the battery. I have NEVER seen a AA battery do that
before. replaced the battery and the mouse was fine. Go figure...
They were some i had laying around with a 2008 code date on them.

I've had Duracells leak in two pieces of equipment I own. It damaged one of
them, and Duracell had to replace part of the item (an Olympus dictating
machine).

I don't use Duracells. I use Eveready and Toshiba.

There's been a problem with counterfeit Duracell batteries for many
years:

Yi also had counterfeit Duracell batteries that could explode.

Trainer says he saw counterfeit Duracell batteries for sale
at local supermarkets and drugstores recently. He turned
the package over, he said, "and the word 'China' was misspelled."

60,000 counterfeit Duracell batteries have recently been
found by Cook county sheriff’s police in a warehouse in Elk
Grove Village. The counterfeits looked authentic having the
copper tops and the shooting star on the packaging. The
way the fakes differed from genuine Duracell’s was their
potential to explode and also to cause brain damage.

A few years ago, a friend tested two types of batteries sold by
Costco, Duracell and Kirkland using his CBA II tester. I'm too lazy
to find the emailed results, but as I recall, Duracell were just
barely above the specified capacity, while the cheaper Kirkland house
brand were well above spec.

mine has done that twice now, once while I was sitting here and once
while I was away, clear liquid from the cell..

Something strange happens now and then that shorts the cell.

I have one of the early model Logitech wireless Ir dual systems.

Some rodents can't burp, belch or fart. Just feed them some bicarbonate
of soda, and stand back ...

(no don't do it, I didn't tell you to do it, you did it, ah, ok - what
happened?)

I was always told that food producers often put out plates of coca
cola or pepsi and each morning would come in and gather up the dead
rodents. All killed without toxic chemicals, well at least in most
peoples opinions

Hi!

Well, here is one for the books. No damage done, but about as
strange as it gets.

Well, that's a good thing. At least nothing was damaged and nobody was
hurt (apart from the battery).

It's actually quite impressive the amount of current that a shorted
(or damaged) alkaline battery will produce. Such a battery can't
sustain that sort of energy discharge for very long, but they will put
off a LOT of heat for a few seconds--maybe even some light!

NiMH and NiCad batteries have much higher energy storage capacity, and
would probably be even more "interesting".

I've had about equal luck with all the major battery brands, and even
some surprisingly good results from "store brand" batteries. Sometimes
you just get a bad one...

William

NiMH and NiCad batteries have much higher energy-
storage capacity [than alkaline]...

Not all of them. It depends on their capacity.

I would be more correct to say that NiMH and NiCad cells have an even lower
sournce impedance.
