All You Need to Know About Using Vape Batteries - Our Guide

When it comes to creating a custom vape mod, one of the things you will need to understand thoroughly relates to the batteries. That is because the battery powers the entire device, and using the wrong one can result in a device that does not work or provides an unpleasant vaping experience. Not only that, but using a faulty battery can also be a safety hazard. To help you stay away from any of the mentioned problems, we have highlighted all you need to know about vaping batteries and using them safely. 

1. Battery Type

There are two main types of batteries used in vape devices: internal batteries and external batteries.

With external batteries, you get to enjoy much more battery life and the ability to choose any battery. However, these batteries are generally much more expensive, and it can be tougher to store these compared to internal batteries.

On the other hand, internal batteries are much cheaper than external batteries, and it is relatively easy to replace them. Unfortunately, if an internal battery does not work, you may have to replace the entire device because the battery is built-in. It does not help to know that an internal battery is much more likely to fail than an external battery, too. 

2. Battery Size

Battery sizes will usually come in numbers like 18650. The numbers state the dimensions of the battery, where the "18" is the diameter, and the "65" is the length, both in millimetres.

In most cases, batteries like the 18650 will be used alone or as a pair. The 18650 is the most common because it works with a lot of different kits and is considered the standard among all batteries. There are many other options, such as the 217000, but those may be a lot less accessible. 

3. Battery Capacity

Battery capacity is measured in mAh, which stands for milliampere-hour. Generally, the more mAh is indicated on the battery, the longer it will last. However, many factors will affect this, such as how often you vape and how old the battery is. Obviously, the more you use the battery, the shorter its lifespan. However, an old battery will not be able to hold a charge as effectively as a new one, so that is something to consider if you ever consider purchasing used batteries.

4. Battery Safety 

Never, ever use a battery that shows signs of damage. That is because broken batteries can put you at risk of serious accidents, such as a vape kit blowing up and the like.

That being said, you still need to be careful with undamaged batteries. For example, you should never charge a battery without keeping an eye on it, nor should you store it in a loose bag or compartment. You should also keep your batteries away from any sources of heat or light, and replace them every two years or when its life cycle has ended.


With these considerations made, you can pick the right battery to help you achieve the perfect drag and provide a safe experience. Now, if you are planning to get batteries, be sure to get them from a reputable source. That way, you know that these batteries come in the best quality possible, ensuring a long lifespan and safe usage.
