It was a black one and it blew away twice when I turned the blow dryer on. The first time it landed on my shirt, so the second time I turned the blow dryer on low and held it further away. The darn thing still blew away into a black hole this time.

Been There. Done That.

I think whoever Dreamed Up the Idea of a Self-Adhesive Battery Insulators should get a Presidential Medal of Honor. That, or at least, Free Drinks for Life.

    I just put my finger over the insulator end of the wrap, shrink the wrap a bit and then take my finger away and continue shrinking. Once you shrink the wrap a bit, the insulator can't fly out.

    Also a bit of elmer's stick glue on the back of the insulator works.

    I don't have a photo but my batteries are totally ripped and damaged on the ends because I'm not allowed to charge my own batteries and the staff are super careless.

    What I need to know is, is it safe to unwrap them in preparation to rewrap them? And where do you find wrappers? Thank you in advance.

    As others have said, it's more-or-less safe as long as you unwrap them just before you rewrap (it is NOT safe to store unwrapped batteries) and take some precautions:
    • Remove any jewellery that might interfere - rings, necklace with a long chain, etc.
    • Prepare a metal-free workspace before you start - I rewrap batteries while sitting on the living room carpet
    • Avoid using anything metal to get the wrap off - you can often just rip them off with your fingers, but if you need help you can use a ceramic blade or a toothpick or something like that.

    25r's are "thin skinned", that's why I kicked them to the curb.

    Now I use Molicel P26A's. They use a much better wrap, and the company actually embraces vaping as an intended user.
    I would much rather buy batteries from a company that likes us than fix batteries from a company that has told us to go to hell.

    They're also generally cheaper and have been verified to have more accurate and equal or better ratings than the other OEMs.

    I've had good luck with wraps from IMRbattery.

    18650 Wraps/Insulators | IMRBatteries.com

    If you do an order with them, be sure to pick up a pack on Insulators also.

    18650 Battery Terminal Insulators - 20pcs - White Plastic

    Those Insulators are easy to Misplace. And for 99 Cents it is easier then trying to find a Missing one.

    It is Safe to Unwrap a Battery. Just start on the Negative (the Flat End) of the Battery and make a small slit with a knife in the Wrap. All you need is enough of a slit so you can Grab onto the Wrap. Then just tear the wrap off.

    Just Never stick Anything Metallic into the Positive End of the Battery and you will be fine.
    Thank you!!

    I have a new set of batteries in my voopoo but they won't seem to charge like the old pair. First, could someone confirm that any set of 18650 lithium ion batteries should charge? (I don't have the battery info with me.) They are the same size and shape as the old pair. This new pair have red trim on a black wrapper. My friend bought them for me, but that vendor who hates vapers has so many batteries by so many manufacturers I don't know why there's so much variations.

    About the Only think I can think of is are the New Batteries "Button" Top Batteries?

    Just about Ever/All modern e-Cigarettes that take 18650 Batteries use "Flat Top" style Batteries.

    I strongly urge you to stick with mods that have internal batteries.

    This could be from a multitude of different things. If you are not interested in learning about batteries, where to purchase them, or about maintaining their quality, I would agree with UncleJunkle above - stick to internal batteries.

    Are the batteries not charging at all, or are they charging very slowly?

    Potential issues off the top of my head:
    -could be old batteries
    -if you're vaping at higher wattages, you may very well be exceeding the Continuous Discharge Rating for that battery (you'd first need to know what kind of OEM batteries you have, which you cannot tell reliably from a rewrap), which is both immediately dangerous to you, and also extremely unhealthy for the lifespan of your batteries
    -you're using rewraps, so there's no telling what kind of batteries you actually have unless you peel the plastic covering off (I would suggest not doing this unless you plan on learning how to rewrap them)
    -the batteries have been left out in the sun, or in a mod that's been left out in the sun
    -your battery charger is shot

    Black batteries with red trim sounds like Trustfires.
    If so they are a Lithium Cobalt cells, (ICR) and they would be low amp and explosive if improperly used.
    Batteries are still cheap, so never skimp!

    Years ago a man was badly burned, and a large manufacturer was put out of business because the guy decided to use some Radio Shack non rechargeable batteries.

    It seems that the batteries were not charged. They charged them overnight and now they're charged and working fine. Yes, I agree that while I'm here I would do better with internal batteries. Thanks for all the input.

    It shouldn't take all night to charge them, and everywhere I've read would highly suggest that you don't charge them unattended. Glad they're working, but they sound pretty sketchy to me.

    I apologize if I come off snarky, but Lithium Ion batteries are no joke. They're not really intended for individual use, so the safety net they're usually used in (part of a battery pack) doesn't exist.
