Texas Heat vs. e2 Lithium Cell

[AFAustin]

I keep an Infinity Ultra-G, loaded with an Energizer e2 lithium AA, in my car as an emergency light. I haven't had any problems whatsoever, and I figured the e2 could withstand Texas summer heat OK. Recently, I opened up the Ultra-G, and the photo below shows what I found. As best I can tell, there was no leakage nor any visible physical damage to the e2, and it still lights up the Ultra-G just fine---the wrapper just split. I haven't used the cell much, and it reads 1.8v on my DMM.

Cheapskate that I am, I hate to throw out anything that has some usefulness in it. My question is, can/should I continue to use this cell, or am I just asking for trouble? If yes, should I give it a less stressful job, say, in an indoor light? Should I put a coating of clear nail polish over the exposed part?

Thanks for any guidance.

It looks like the shrinkwrap... well, shrunk. I doubt there is any damage to the cell, but I would shy away from running it in a metal bodied light.

Metal bodied lights are everywhere, the battery sleeve that connects the anode [or cathode] is whats important in this matter...and the sleeve exists in practically all the lights I have...with the exception of the SL Propoly 4AA Lux, where the light engine recieves both negative and positive without a medium in which to conduct it from the rear of the flashlight.

Well, from the looks of it theres no addressable concern for a dead short provided the light in question takes a single cell....however if the light uses anything other than a bezel twist on/off operation the light could turn itself on and drain the cell sitting in the car. :shrug:

the only times I have seen shrinkwraps shrunk to this degree or worse is during or after a thermal runaway...interesting...hmmm...suscribed. :thinking:

Since its the packaging in question and not the battery itself I would consider storing the batteries seperately in a storing case of sorts. In the even that the packaging peels far enough to allow contact its still isolated away from anything conductive. Only advantage would be that in the event when you need your light be reminded that you have to install the batteries before you use it

I agree with your points... I think I would retire this particular cell to wall-clock duty.

well, a layer or electrical tape or simply just a layer of 3M scotch tape would be fine for places that uses plastic battery holders

Burgess,

That might indeed be worth a try. Thanks for gently shaking my old brain!

Update: I just sent a message via the Energizer website. I told them I'd be happy to e-mail a photo if they'd provide an e-mail address. I'll report on how this goes.

Thanks again.
