 |
|
During the leaking Duracell discussion last month, I didn't give it much thought - until I opened my LED flashlight yesterday to put in new batteries and found the Duracell C cells had leaked all over the place. Just another data point.
I've bought my last Duracell.

The Dec Consumer Reports AA batt tests show Duracell in 8th place for the alkaline used for a camera ($/50 shots=$0.70). Best was Kirkland ((at)$0.10). Cost for 2 was 2.25 & 0.43 respectively calculated from the bulk packages.
No mention of defects.

I did a return-on-investment study of a variety of
AA alkaline cells about 6 years ago. The original
article can be secured at:
http://www.aeroelectric.com/articles/AA_Bat_Test.pdf
I've since tested a host of additional products
in the AA cell family. From the perspective of
contained energy I discovered that the most inexpensive
cells you can buy are the best $value$. On occasion,
I tested a product that delivered only 80% of the
average energy for the constellation of products
tested . . . but their price was so attractive (on
the order of 20 to 25 cents per cell), that the
cost-per-watt-second of delivered energy was VERY
competitive.
I probably have 100 alkaline cells on the shelf
ranging from AAAA to D and the brands are all over
the map. I've not suffered the indignity of a cell
leakage event for years. But then, my battery powered
devices don't spend much time in dormant storage
with risks of allowing depleted cells to remain
installed.
I'll start keeping dead cells. I'll put a date
on them when I toss them into the common battery
grave and see what happens with respect to leaking.
The last time I saw a leaking AA cell it was a group
of ni-cads . . . and those puppies run down in a month
or so just sitting.

The leaking Duracells I discovered in my LED flashlight had been used frequently during the past 9-10 months. They spent very little "sitting around doing nothing" time in the flashlight.
From the earlier discussion and other anecdotal information, there may be reason to suspect a problem with the Duracell brand. We need more datapoints. Time will tell the story on this subject.
Regardless, I will buy other brands - or as Bob has recommended, the cheapest "generic" batteries.

This may or may not be important, but my father was visiting with me
today about how he had to change the batteries in his DISH network
changer, he purchased some Duracells, and when he tried to install them
he found that they would not fit! Apparently the newest Duracells are
marginally larger than the old batteries that came with the unit, He
ended up purchasing some lesser know brand that were indeed a trifle
smaller just to get them to fit. ?????
Could it be that the larger size is having an impact on the their
covering/protection??

Deems, maybe the Duracells your dad tried in his DishNet remote expanded and
were/are getting ready to leak. I would keep an eye on them to see if they
do.
I typically buy Ray-O-Vacs, because they seem to be the most cost-effective
and are readily available at local stores. I once had contact info of a
Ray-O-Vac engineer up in Minnesota and used to ask him all sorts of
questions about batteries. I wish I still had his info. He told me once
upon a time that Ray-O-Vac alkalines had about 95% the energy density of
Energizer batteries but of course were a lot cheaper and thus were very cost
effective. This is why I've used them exclusively for years. They've never
leaked, but someone earlier on this forum said they come off the same line
as Duracells. Was this ever confirmed? I bought a package of 48 AA
Ray-O-Vacs about four months ago, and about half of them are in use. I
haven't seen or heard of any of them leaking.

Interesting piece of information. Could they be swelling up after a
period on the shelf and as a result rupturing (leaking). My recent
experiences have been just to many incidents of their leaking - one
of the reasons I picked Duracell is before they never leaked where as
other cheaper batteries did. Now they appear as being
no better. Sure would like to know what has changed about them.
