Battery Safety - Visible Signs Of Defects

[snowman123]

As a safety measure and to prevent damage to your mod, do not use batteries which have a broken plastic seal layer near the positive terminal (see picture).

When the plastic layer is removed (I stripped the insulation just to expose the layer - see pic), it exposes the negative layer of the battery which encloses the chemical components inside.

Using such a battery will create a short circuit damaging your mod permanently. The risks are at the highest when removing or inserting batteries because the battery contacts on the mod can easily touch the edge of the exposed layer. So, don't try to save a few bucks, just get new batteries for safety and to prevent any unwanted damages to your mods.

Hopefully this helps someone.

Good points @snowman123 but if your battery chemistry is still in good condition then this and a new battery wrap will save you from throwing a good battery away.

Have you ever tried this before? I am honestly a bit sceptical about using plain paper gaskets. I doubt this will be a permanent lasting fix because I see the paper gasket getting damaged each time the battery is inserted and removed especially in certain mods eg. Istick where the battery fit is extremely snug against the brass connectors. Also batteries tend to warm up sometimes if charged inside or during use. Not sure how well the adhesive layer would hold up.

Personally, I think the best fix is to use heatshrink tubing over the battery. This would be the most durable. Of course, this is not a safe option because heat would have to be applied to the battery to do this......direct heat + lithium battery = explosion! Not worth the effort and risk to me.

i have a rule to inspect my batteries each time i charge them . no exceptions

99% of the time i can just rewrap them when there is a nick in the wrap before any damage to the insulator

 

[snowman123]

Do you use any special material/tape to rewrap? Or will normal Nitto tape do the job?Just curious.

i get 18650 battery sleeves. they cut to size so you just slip them on and use a heat gun to shrink them .

got the sleeves from @KieranD

Was worried about applying heat to the battery. Will definitely give this a try.

Nope never used them before. I usually put a clear wrap over my batteries when I get them and they stay well protected. There are posts on Reddit that recommend using these gaskets and there are reviews that suggest they work but I get your point/concerns about it being paper. I`ll have to include some in my next order just to test them out
On the heat shrink side, I just use a hair dryer to shrink the wrap. Works great. The Lithium Ion batteries that I use do not explode but will vent and flame out if over heated or if I ever short circuit it.

we not talking blow torch here ! lol

you can even use a lighter > dont bother with a hairdrier, it wont heat up evenly and then the wife runs into the room wondering what your doing with the hairdrier and you dont want to even try to explain that situation....

@snowman123 I think I might have got my wires crossed here. Were you talking about the wrap/plastic cover that covers the entire battery or the black/white disk that sits around the positive terminal in your op?

 

[snowman123]

Good points both regarding the hairdryer and the blow torch!

Fortunately, I am a tech so I have access to various test and repair equipment. I think hot air smd station might do the job. Lowest heat setting, lowest airflow setting with a narrow tip. Will give this a try. Best to start now with prevention better than trying to fix when the damage is done.

Actually both. I have a couple of batteries that have a few nicks on the insulation and some that are missing the top gasket plastic layer.

Replacing the insulation/wrap as @shaunnadan said is easy, slide precut wrap over the battery. Make sure the length is right on either side and bring the heat. Iirc the temperature required to shrink the wrap is around 70 degrees Celsius.

Done it many times. It's safe. I've re-wrapped batteries many times and I have sheets of those paper insulators and use them when needed. Works like a charm.

Can we ask @KieranD to bring some battery wraps along to the vapemeet? But I guess he should bring many... @shaunnadan

Can you post the request in the who has stock forum and he can respond.

Will do

Here is a handy cheap little heat gun I ordered from www.banggood.com because I'm using a hair dryer at the moment for the battery wrapping. The heat gun will be more precise and also useful for other stuff.
