DuraHELL batteries

(1/54) > >>

NoisyBoy:
We have all watched Dave's video on leaking alkaline batteries (or attempting to make them leak).  I never took it seriously, as I often thought my kids had left the toys on and running the battery down which caused them to leak.

That's until tonight, I was looking for some batteries, and I went into my battery storage box for disposable alkaline batteries, which are all Duracells.  Out of the corner of my eyes, I noticed leakage in a brand new pack of batteries, and I took it out to dump out the leaking batteries.  Out of curiosity, I decided to check all the batteries. I found half a dozen packs of batteries which are all leaking.

Now, these are the premium cells such as Quantum and Ultra with 10 year guarantee, plus one pack of Coppertop, all with expiration at least 5 years out as we go through them quite rapidly in our toys.  In one of the Quantum pack, almost every battery was leaking, some on both ends.  The battery storage box is in a room that is temperature and humidity controlled all year long, and always out of the sun.  So the leakage can only be caused by defect or poor design in the batteries.  They were also bought in different time from the office supply store, so it is not a single defective manufacturing batch of batteries either.

Luckily, I replaced all my DuraHELLs with Energizer Ultimate Lithium in all my handheld test equipment a while back.  But for those of you still using Duracell Alkaline, please heed this warning and don't let your equipment ruined by leaking batteries. 

For me, I definitely will never buy another DuraHELL again.  I probably could have exchanged the leaking batteries as they are all in the unopened package and many years before expiration date, but why take the chances.

Something is definitely wrong here. There's no way every pack should be like that.

Maybe your office supply store isn't a diligent as you with their storage.  :-//

Yes, that's very suspicious

SilverSolder:

Where could you possibly store them that would excuse this leakage?  The sauna?  :D

It seems that Duracell is all about giving the batteries a nice glitzy paint job to look cool and advanced, but beneath the surface...    cheap, cheap, cheap.
