Ok pretty sure my battery is beyond saving

[Jjb12491]

Thought aliens were coming through my kitchen window ran over to find my battery welding its self to the charger gave it a swift ninja kick off the wall to find my battery looking like that and some melting on bay one on the charger now my question is is my charger still good on bay two un touched despite my better knowledge it is charging that battery fine as of now (vape or die?) any one have any experience with the plastic peeling off the cell like this before?

I believe if the wrap is coming undone at the top that's not a good thing as you're exposing more of the positive which would not be good in a tube mod if that top portion touched the side of tube. I personally would not use that battery again. Better safe and just discard (properly) and replace.
As for the charger... I'm not exactly sure.

I did put a multi meter to the exposed part and it is not a positive part of the battery so essentially put voltage through the outer casing of the battery I mean I know it's not too safe how ever its my only battery until my two new he2s come in...

i know this is a day late and a dollar short but you need to have some of this on hand for such occasions
$1.18 Single 18650 Battery PVC Heat Shrink Tubing (Green) - 2m in length at FastTech - Worldwide Free Shipping

you can shrink it down with a blow dryer, Google has plenty of video's on how to apply this wrap..

in a pinch i have used small pieces of blk tape to cover exposed areas but it doesn't hold very well and i really do not recommend it for any long-term period of time best to either discard or re-wrap....also invest in a good charger/batteries this is not an area to skimp on.....i would not trust the charger if it already fried a batt.

The upper weld mark in the picture is on the outer casing which is negative. I'm not sure from your picture, but I think there is also a weld mark on the top of the positive battery post. If this is correct what likely happened was a short between those two spots on the battery. Typically the positive contact of the charger is shaped in such a way as to make this really hard to accomplish unless the battery was out of position and the wrapper was already torn up. I suspect you would find weld marks on the charger contact too. If you don't, then I think the charger has an internal short and I would consider it bad and not use it again.

So, is the battery OK? If the charger bay got hot enough to melt plastic and that heat came from the battery, it could easily be toast. I think you charged it in which case it should make around 4.2v right after charging. Did it? What was the voltage right after the incident? What make and model of battery is it? If these batteries go too low in voltage they can become unstable. Less than 2.5v is too low for all of them. Less than 3v is too low for some of them.

As Sando said, heat shrink tubing is the correct way to fix the wrapper issue. Here's a tutorial on how to do that: How To: Remove "Button-Top" and replace battery wrapper/jacket. You do not of course want to remove a button top, just replace the wrapper. You need that white insulator in the pictures that's shaped like a doughnut and goes around the positive battery contact.

If you have any doubt the battery is good, don't use it. If it has gone bad the right (or wrong) way it could explode on you and that can get nasty!
