Baterry stripe , little concer

[Roxxette]

First thank you in advance to anyone that looks here i appreciate.

Ok so today i was charging my batterys and after a while i came back and they been done , when i removed from the charger i noticed that one of the batterys had the little plastic circle in the down side a little ripped so stupid me pulled it and now these is how it looks:

Is these battery still good ? Or i should toss it ???

Thanks again !

Personally, i definitely wouldn't use it, not worth the risk.

Nope! Toss it! Any cracks or tears in the shrink wrap is an accident waiting to happen.

I don't see a problem. The heat shrink wrap is equivalent to the paint on alkaline batteries. Many different manufacturers sell batteries made by the same manufacturer. The shrink wrap is their way of installing their proprietary logo and design on a plain silver metal cell. That's the negative end, anyway. It's designed to contact the case of the device.

That would entirely depend on the application!

Many a learned individual would disagree with you. I personally air on the side of caution. IMMHO there has been far too many incidents of late. Do we need another one? I am not speaking with a vendor's point of view, but as a safety minded vaper.

I'd give it a wrap with electrical tape or some other vinyl tape just to be sure, since it's only some exposed metal case.

I toss them when any damage occurs, or when they no longer hold charge as long as they used to. It is much safer and cheaper to buy new batteries then to chance a horrible mishap. No tape adding here, just asking for more to go wrong in my mind, say tape sticking to side of mod and can't remove it, bits of lint causing some sort of short, etc...

I was going to post a similar question. I've got a practically new AW IMR 18650 that has a little tear in the shrink wrap right about in the middle of the battery. Other than that it works fine. Charges fine, puts out 4.2 volts fresh off the charger.

Does anyone know if you can just get some replacement shrink wrap and rewrap them? I hate to throw away a practically new battery that is otherwise working fine, but of course I don't want to vape on something that's going to explode either.

The one thing that I would worry from with a tear in the wrap would be the ability to cause a short in the battery since the cell could now touch a metal something inside the mod, which is not good for batteries... There is one gentleman here that I have seen wrap his batts, but I do not know where he got the wrap from...

 

[DaveP]

All but the top center contact is negative (ground). What you have to worry about is the center post touching ground. What happened here is probably from repeated insertion and removal from the charger contacts. I wouldn't be worried about it, but anyone who is shouldn't use it. For $5-$7, you can get a new one.

Shorts can cause explosions, but I don't see that happening here unless the mod has wiring that could present a positive voltage contact with the case of the cell. If that's the case, THAT problem should be fixed.

ETA: If it's a protected battery, the shrink wrap also encloses the protection circuit at the bottom. In that case, there's a thin disc (protection module) attached under the negative end inside the shrink wrap. If that's compromised, there could be an issue.

I was just looking, and found some shrink wrap at a place called Radical RC. I might order some and see if it works.

 

[Roxxette]

Thank you very much to all the people that took the time to respond , the mod im using is the Alpha Ultra incase it matters BUT il try to get the wrap locally if not il probably toss it out

 

[Roxxette]

Well hmm i have used times and also have charge it :-/ no problem so far abd battery doesnt get hot.

TWO "IF'S"

1. - IF you are not using this battery in a stacked configuration in a tube mod without an insulated inner tube surface...

AND

2. - IF there is no side conductor exposed by this tear...

You're OK to use it.

 

[Shortstuff116]

I'm not sure what mod the "Alpha Ultra" is or what size the battery is, but if it's an 18650 and there is room inside your mod, a pre-formed dime roll (used to roll dimes with) is a perfect fit for a sleeve for the battery in the meantime.

 

[DonG]

as long as there was not a protection circuit (small metal disk) on the bottom of the battery then I would use it (maybe with the electrical tape or dime tube cover. if there was a protection circuit, then there is a small positive "ribbon wire" from top to bottom on the battery under the shrinkwrap. A tear in the wrap could result in this wire shorting to the body of your PV; in this case toss the battery or find some good shrinkwrap.
