I recently ordered on eBay 100 energizer AA batteries.

I tested them using a simple battery tester from radio shack. 4 were dead,
one was near death, and 95 were at an identical high mark, but just a
"little" below an energizer I bought from a retail package from Home Depot.
The tester is simple and unmetered, save for a "75%" mark. The needle moves
up to *almost* the same spot as my control (retail) battery does.

They were shipped in 2 corrugated cardboard boxes, roughly the height of an
AA cell. 50 in each, all standing up on the negative (flat) end. So
(especially if they are stacked) the top and bottom of all the batteries are
touching the top and bottom of the cardboard box. HUGE speculation: If the
cardboard is even minutely conductive (humidity, acidity, or whatever) then
I have effectively a wired in parallel 1.5V "50xAA-amp" "battery" that is
shorting through its own packaging (?)

Is there another possibility for this, other than just lesser quality
batteries? And is the cardboard shorting even possible? I'm working with
the seller to try to figure this one out. He's asking about possibly
putting a plastic or foam sheet above or below them. I'd appreciate your
thoughts on all of this.

It seems that the cardboard would have to be wet in order to be conductive
enough to cause a problem but it would be very easy to run a simple test
just using a meter to measure current flow.

No, they're just crap.

No.

I buy 'brand name' dollar store batteries and they're fine. The dollar store
button cells may be another story.

Most likely 'fake' Energizer batteries. Common problem, take a very
cheap import battery, put a new lable on it, and sell it for *more*
than it is worth!

As to moist cardboard draining them, IMHO unlikely unless the
cardboard or moisture has some contamination (salt?) that increases
conductivity.

Easy enough to test, just put some (say two or three) batteries in
series and connect to cardboard while measuring the current. Bet it
reads zero.

I think you got scammed with sub-standard (or very outdated)
batteries.

I've heard of such things....is there a way to distinguish batteries I
wonder?

Yep, but I am also wondering about the acidity. I know from my comic book
collection years that all paper products, and in *particular* brown
corregated cardboards, are far below PH-7. I don't know if there is a salt
that is in it, or something else very mildly conductive. I'm getting more
convinced from you guys however that I'm barking up the wrong tree here...

With my multimeter, a miniscule current flow would be within the noise.

Understood. It's also possible that the seller doesn't know /his/ supplier
well enough, though I'm certainly not making assumptions in any direction
right now.

I did notice that a couple of the batteries didn't have dates on them at
all. And some of those had "made in singapore" stamped on their sides. Is
it possible for energizer to be manufactured there on occassion?

The seller to me buys the energizer-AA's in bulk lots of 5000. He is
interested in getting to the bottom of this---is there a way for him to know
what's what? I have moved beyond caring about this particular order and am
interested in figuring out /how/ to safely buy batteries cheaply.

For example, the children's toys eat up AA's like candy, and we have a baby
swing chair that uses more C batteries than a woman's prison... ;)

So I ran a little test.
Somewhat humid cardboard (sitting in my unheated garage in Seattle in the
middle of winter) measures over 100 megohms on my multimeter.
Sopping wet cardboard (tapwater) measures 1 megohm. Test points 3" apart
although it didn't seem to matter much.

Energizer rated at 2850 mah
Leakage into wet cardboard would be 1.5/1000= .0015 ma.
Time to discharge battery would be 2850/.0015=1.9 million hours or somewhat
over 200 years.

I suppose the water could have contained more ions than my tap water but
knowing that the human body is quite conductive I also checked the
resistance across my tongue and found it to be 1/10 that of the cardboard so
it would still take over 20 years to discharge the battery.
I guess I would look elsewhere for the dead battery gremlin.

Though you don't have to buy the most expensive to get a decent product, you
do have to watch what you buy. I've bought some "cheap" batteries in my past
and well - not only did they go dead fast, they leaked and caused some
damage to the item. A bargain - it was not. The damage was realitively easy
to correct - but I knew then not to buy "some" off brands.

Sounds like you guys got a bum shipment of batteries. I tend to agree with
the other guys, it is highly doubtful the "shipping" box caused them to go
dead. It would have to have been made damp and have good contact - top and
bottom of cells.

Report the seller to ebay's fraud department and have the idiot banned from
ebay. If more people would report these scammers it might make it a better
shopping experience.

Pretty extreme retribution toward someone whose product was 96% satisfactory
and who was working with the buyer to resolve the problem.
Perhaps you could share your Ebay id with the group so we could avoid doing
business with you.

Do we "really" know the seller was working to solve the problem? OR just
blowing off the buyer with a bunch of questions - he himself may have had no
clue of? I'm not saying the seller wasn't trying to resolve the issue - but
there is no way to prove it. It is as we've seen, a far stretch to imagine
"cardboard shipping container" to short out batteries. OR some being dead as
I believe was also the case.

In buying bulk, you're probably always going to have some defective product
show up - I've had it happen to me. Actually, maybe the seller could have
offered to reimburse some money for loss - but if "he" wasn't BSing the
buyer, then he had about as much knowledge and chance for a refund - as the
buyer seems to have had. Us trying to prove the case for the buyer OR
seller - most likely won't make a damned bit of difference to the original
supplier if the seller indeed relied on one.

When you factor in all the product in a "bulk" deal - you figure out your
per piece cost and then see what you've lost. Is it worth dicking around
trying to prove anything - or just toss in the trash and forget about it?
Batteries in bulk are usually pretty cheap. At our local store, I can buy a
4 pack for a $1 - batteries I use often with no issues. OR I can buy a 12
pack for a $1, which I HAVE had issues with - leaking. Price doesn't always
dictate quality, but sometimes - it does.

Just my 2 cents

You can buy rechargeable alkalines. They'd be good in service like this.

You can also recharge regular alkalines with the charger. They say you can't
but you can.

I can buy an 8 pack for $1 here. They're good. The fake Energizer 12 per
pack are total crap.

Kind of reminds me when i bought a brick of what i thought was
Duracell's AA's. after the first set of cells died in a short
lived period, i noticed they said Duraking and had the same copper
top casing and all.

Yeah, that's a sure sign of crap IME.

All such notions were mine from the start. The buyer isn't the one with the
questions. He is just interested in what I discovered, and seems to be
genuine in this, or so I think.

product
show up - I've had it happen to me. Actually, maybe the seller could have

seller - most likely won't make a damned bit of difference to the original
supplier if the seller indeed relied on one.

Your wording here is a little unclear to me, but I'll try to clear it up by
saying that the seller *did* offer me a full refund. I didn't press him on
this to see if it included shipping or not, but I think he would have.
*Plus*, he also without me asking to put in a small package of 16 AA's (some
unknown brand) for free. I really just get the sense that this is a guy
attempting relying on feedback and because his feedback has been almost
entirely positive he simply was unaware of any issues.

When you factor in all the product in a "bulk" deal - you figure out your
per piece cost and then see what you've lost. Is it worth dicking around
trying to prove anything - or just toss in the trash and forget about it?

Discussions are valuable when they instruct, so this seems like a worthwhile
conversation. There's much here for me to learn about the consumer battery
world, and I'll leave it at that.

You don't need to bid on the item to report fraud, hell I've had a few crooks
banned before their auction was over. All in the test equipment department.

Is there a reliable 3rd party battery reviewer/tester/etc. ? Perhaps
consumer reports? Or does anyone else know of any?

I can tell you from a fairly thorough experiment of mine involving a Sony
Walkman (analog audio casset tape) in the gym for nearly 2 hours every day,
that AA-energizer (classic energizer, not e2 or anything else fancy) beat
duracell's standard coppertop alkaline every single time. Big thorough
experiement, but very narrowly focused on 2 brands, one device, and one
"way" of using it (left on with no stops and restarts). But it was without
deviation: E beat D in this narrow case.

But what of BJ's "Berkely & Jensen" OEM'd brand? Or any of the other
million mumble names out there, probably 99% of them originating in asia.
Any good ones people like?
