Beware of Energizer e2 AAAA batteries. Leak problems.

[Lunal_Tic]

Just a heads up for anyone using Energizer e2 AAAA batteries. I've had a bunch, 20+, go bad at different times.

*first batch of bad ones*

The most recent was today in a Streamlight Stylus Reach, destroyed the light. Weird thing was that the leaking ooze turned the light on. Apparently the batteries leaked, completed the connection and drained the remaining batteries so that they leaked as well. I took off the tailcap and the light stayed on.

It's really annoying since "A" it's my computer tool bag light, and "B" the last time I tried to get satisfaction from Energizer over bad AAAAs they sent me a voucher for considerably less than the cells involved. I may not even contact them about this one to avoid the frustration.

I hate to tell you, but if you are having that many go bad, it's gotta be one of two options:

A) you are storing them very incorrectly
B) you got counterfits

There is just no way that many cells would randomly go bad.

I appreciate your perspective however I will have to disagree. They have been stored and used in the same manner as my Duracell AAAAs and the Duracells have yet to leak. Also the Energizers were bought from multiple sources in the U.S. so it's unlikely that they all had counterfeits; assuming for the moment that someone would go to the trouble to counterfeit such a low volume battery.

In that case, you pretty much have to be storing them incorrectly.

Did any of the cells go bad in storage, or were they all in use in something when they went bad? Were they in anything besides Streamlight Stylus lights? I have close to half a dozen different of the AAAA-powered Streamlights and have had nearly all of them leak. I've learned my lesson with those as well as Mags and other alkaline powered metal-body flashlights. I don't leave batteries in the lights for any sort of long-term storage, in other words, if I'm not going to use the light within a month or so, I don't leave batteries in the lights. Alkaline leakage (with any brand, evne the big three) in metal body flashlights is very very common.

I'm afraid once again I have to disagree. As mentioned above, none of the Duracells have suffered the same fate. Nor have any other versions, AA/AAA/C/D/N/LR43/LR44/N12V, stored in the same place and manner had these problems.

I would be more inclined to believe there was a bad run since they were all purchased within about a year of each other IIRC but since I have had no problems with the Duracells I'm going to go with them from now on.

The ones pictured above went bad in storage. The others have gone bad in Stylus lights but I haven't put any in Aunoc lights which are the only other AAAA lights I have. Duracells and one set of non-e2 Energizers (came in a new light about 4 months ago) in the Stylus lights haven't gone bad yet.

Just a tidbit, e2 titanium AAAA are no longer made, so they must be quite old. I must admit, I saw "e2" and originally assumed lithium AAA's, but it still seems quite odd that ALL of those cells leaked.

The photo above is from a good while back and those were dated for 2008. I know that the e2 AAAA alkaline isn't on the Energizer site anymore but they are still for sale.

With Energizer now also branding alkalines as "e2" it does make for some confusion. I wish they did make a e2 Lithium AAAA, I would probably use it since I've had pretty good success with the AA/AAA versions.

Dated for 2008 means they were likely made about 6+ years ago. Their e2 AAAA's have long since been replaced with regular non-e2 AAAA's.

Once again, as mentioned previously that photo above was taken a while back (2005) which means at the time of the photo the batteries were newer yet still leaked. As for the second point, Energizer e2 AAAA alkaline batteries are still for sale, hence the warning. A simple Google search will bear this out.

All of these that I have ever had have also leaked - and long before the stated 'expiry' date. Just as well they are no longer made.
