View attachment 499715 So I pulled my batteries out for a charge the other day and first thought maybe some ejuice got on it but I don't believe that's the case now. Thoughts? Is this unsafe? Is it leaking or what's going on?
Guru or not, that's probably the stupidest post I've seen on here. Any kind of damage to a battery or its packaging can relay damage that is invisible to the naked eye (My father works with batteries a fair bit) and continued use of a battery can lead to it combusting or leaking corrosives everywhere.There are two things going on with that battery. The mild darkening that goes around the battery and the spot that's darker.
Here is a thread about the mild darkening. There are a bunch of pics from different people who experienced the same thing. I retired a couple of batteries that had that happen to them and posted pics with the wrapper removed from one. There was nothing wrong with it, it's perfectly safe.
I have seen the dark spots a couple of times before too and saw one pic with the wrapper removed. It was also not a problem. Wish I had bookmarked that but I didn't. This is more of a worry for me than the mild darkening because I've only seen it a couple of times so I'm not as familiar with it. I also have not had it happen to me so I don't have personal experience with it.
I wouldn't worry about it, but if it bothers you it's pretty easy to take the wrapper off, inspect the casing and then re-wrap it if you're happy with it. Here's a tutorial on how to do that.
Hope that helps
"I wouldn't worry about it"???? Really?
Toss those batteries. That is NOT suppose to happen IMHO.

I'm all about battery safety and I think anyone who has seen my posts the last few years knows that. I doubt you read the thread I linked to in my first post. Quite a few people found the same darkening on their Sony batts. Some reported the same with Panasonic and AW. When I checked mine I found both my Sonys were the same as well as my two MNKE, I just had not noticed it utill I looked for it. If you read the thread you'll see my reaction was concern about what was going on at first.
Then I did some research and combined with the number of people who were reporting the same thing with their batteries decided mine were safe and continued to use them. I then took the wrapper off my MNKE and found nothing wrong underneath it.
These discolorations happen and people occasionally notice it, become concerned and post about it. I've seen it often enough I bookmarked that original thread. I suspect most batteries that have translucent wrappers will exhibit this effect to some degree eventually, but my sample size is small so I don't claim that is a fact.
It is simply wrong to say with certainty that any damage to a battery is cause to toss it. I've replaced a few damaged wrappers over the years and will be doing all five of my Sonys in the next week because the wrappers are in bad shape. It's easy to do and quite safe as long as you don't use any metal around the positive end as the tutorial I linked to points out.
It's very easy to say recycle a battery that has any damage to it and if that's how you want to deal with yours you will not get any discouragement from me (though I might suggest you mail them to me and I'll take care of the recycling for you ). I post what I've actually learned in an attempt to get that information out there. I do my best to be clear about what I know for sure and what I suspect but am not sure about, as I did in my first post. People can do what they will with that and that's fine with me.
That's fair enough but unless someone van 100 percent guarantee that it is just pooling of glue on their battery then surely they should not be risking their fingers using the battery?
To your experienced eye, yes you may be satisfied with its quality but I am just expressing that I think it is incredibly silly to continue use of a suspicious cell.
From a similar experience, I had batteries in a lime green coat in an old model airplane. Over time they naturally had pooling. My dad said to bin them but I didn't and a few months later, they leaked over the aforementioned plane.
And I would send you them if I used a mod that took extrenal batteries.
Tl; Dr: unless your sure the damage is just glue then bin it.
