Battery Holders & How To Rewrap a Battery

By Nick Bessette

Most of us use our batteries day in and day out with little thought about what happens to the most delicate part of them when we put them in and take them out of our devices. A slight tear here, a nick there, no big deal right? Wrong! The thin outer skin of our batteries is the only thing protecting them from shorting on the metal casings of our mods. Keeping an eye on your battery wrappers is something that is not only overlooked by many; it is downright ignored by a good percentage of vapers.

Essentially the outer wall of a battery is just a big negative terminal hence why the positive terminal is isolated and the wrap covers the battery except on the negative terminal itself. If you have a tear near the top of your battery wrapper it can potentially arc with the top of your device and cause a short. “It’s okay, I use a regulated mod,” I can hear some of you saying. It doesn’t matter what type of mod you have, your battery can still make contact with the battery door and cause a short not to mention when you have the batteries outside of your device.

Battery wrappers are dirt-cheap and easy to install so there is no excuse to walk around with dangerous batteries. Grab your batteries and go over it top to bottom, can you find any nicks? What about small tears?

If so it’s no big deal, just get yourself some battery wraps and follow these easy steps:

1 Remove the old wrapper by getting under the edge with your fingernail and tearing it off. The reason we don’t use tools is because we don’t want to damage the cell.

2 Prepare the new wrapper by trimming it (if necessary) leave it about ¼” long on both ends so that it will cover the top and bottom properly.

3 Slide the new wrapper onto your battery leaving an even amount of room at the top and bottom.

4 Take a hairdryer on high setting or heat gun and run it over the battery until the wrapper shrinks over the battery.

5 That’s it! Now your battery is like brand new again. Don’t forget to label it with the date it was purchased so you know when it’s time to replace it.

Batteries are not very volatile when used properly; usually it’s what we do to them as vapers that makes them more likely to malfunction. By reading these safety articles I hope to prevent accidents that end up on the news and put vaping under the microscope of the public and government leading us ever closer to being regulated. That being said another thing I see is vapers putting their batteries in their pockets with other metal objects like their keys or loose change. THIS NEEDS TO STOP IMMEDIATELY! I can’t stress enough how dangerous that is as we’ve seen with the latest case of a battery exploding at a Kentucky gas station. One of the easiest ways to keep yourself safe is to store your batteries properly when they’re not in your device.

Our devices would be nothing without the batteries so why not keep them safe and sound? There are a number of products on the market that are designed to keep you and your batteries safe. One would be a simple plastic battery box. These usually sell for about $1 and normally hold two batteries, which make it the perfect companion to your average daily vaper. Another great

product is the silicone single battery sleeve. They’re lightweight, inexpensive and easy to carry around with no added bulk. They make it safe to carry around in your pocket even with keys/change although STILL not recommended. Finally a slightly more modern way to carry around spare cells, the 3D printed battery case. Expect to pay a little more for these (around $10-$20) but with varying designs and a little extra style; it’s definitely a worthy investment.

So now you know how to revive your old badly wrapped batteries and how to keep them safe but what about those batteries that have seen hell and back? Maybe they’re dented from using it in your hybrid mech mod or have scorch marks and scratches on the terminals or maybe they don’t seem to hold a charge for very long anymore. That’s what I like to call a “lost cause.” It’s time to move on, I know it’s tough because they served you so well for so long but there comes a time when it’s just better to walk away. But hey, think of the great feeling you’ll have walking out of the vape shop with brand-spanking-new batteries, that should make you feel a little better, right?
