"My battery wrap looks damp inside, is it OK to continue using it"

[Joules_Verne]

Not strictly Reo-related but might be interesting.
I've read a few posts about batteries looking damp inside the wrapper and I remember Ryedan replying a couple of times.
Well, here's one (of 4) that I made earlier using 2ml tube of De-oxit Gold and a tooth-pick as applicator.

+ve end, no De-oxit contamination, easy to contain the De-oxit to the button-top

couple of days later, -ve end after De-oxit spread around with tooth-pick, must have touched the wrapper and wicked underneath.

-ve end, another view.

I had harboured the idea that continual warming/cooling-off of the battery might lead to condensation under the wrapper depending on the environmental humidity but it looks like I may have unintentionally proved the theory with a De-oxit application .
All 4 VTC5's were clean before the De-oxit application and all four showed similar markings after.

I have the same markings on my VTC5s. I have no clue as to what it can be. They all exhibit the same staining. All of my batteries still charge just fine and hold a charge, so I don't imagine it's hurting anything.

Lord, I am getting old and my body falling apart and my eyes now too. I can't see it. it looks like the end is stained, slightly off colored. Is that what your talking about?

 

[Joules_Verne]

Yep unsure, that's it, like a dirty water-mark under the wrapper.

All of my Sony VTC4's and VTC5's have these weird marks....mine are more like streaking lines and some dots.

I initially thought it was my noalox seeping into the wrapper, but I really have no idea what it is.

Yeah pretty much same thing here, I only have Sony batteries and they all are starting to look like that. I'm starting to wonder if it's just Sony batteries in particular. Also, just out of curiosity...how hot do you run your coils? I have been running mine hot lately as I've taken a liking to a much hotter vape. I usually net around .2 to .5 ohms. On the lower end of my spectrum, I've noticed my grand, rm5, and even batteries starting to get warm after repeated use. I'm thinking the heat the battery generates is mainly what's causing the damp look under the shrink wrap. My thought is that as I the battery heats, there's enough heat there to shrink the wrapping a little more giving the effect of the wet look.

Some of my brand new AW IMR's have developed that in just the few short weeks I've had them.

Half of mine are the same way. They will eventually develop little spots under there as well. I'm certain the spots are oxidation from the moisture attacking the metal of the battery. I've been running mine like this for months and months with no issues, voltage changes or performance changes. I'm likely to replace them soon though.
So don't worry, it's not a problem. Most of my batteries are like this as a result of juice getting on them.

Use black wrappers.

Black wrappers would be the cat's t!ts! But black wasn't an option when I bought mine.

Thanks, folks - although I cannot remember ever being in a Lavender-Pink mood !
I'm not bothered by it, have some green wrap on the way, just thought it might be interesting in that I could tie it down to something that I had done that caused it to appear.
