It’s essential to choose the best vape battery. Otherwise, it won’t last you throughout the day or provide your vape with the power to give you enough puffs . Information about batteries can get quite technical, but we’ll lay it out simply and efficiently so that you can learn fast. 

Once you learn this information, you’ll be much better informed when buying vape mods because you’ll know how long they’ll last between charges and how much power you can get out of them during the day. That way, you can see if the manufacturer’s claims are accurate. 

After we’ve explained the characteristics of vape batteries and how they work, we’ll discuss the three best vape battery choices. You’ll learn about the features and the benefits of each one and have a link where you can find out more about it.

When considering the best battery for vape, there are five essential characteristics to keep in mind. You can look at them one at a time, but it’s better if you consider them together. If the best vape battery you can find performs well according to each of these, then you’ll know it’s the right choice for you. 

The five characteristics are:

Each one is equally important, so the best thing you can do is read through the sections below to familiarize yourself with each characteristic. 

There are two areas your vape battery can be situated - external or internal. If your vape battery is internal, then you won’t have much to concern yourself with. You can simply plug the charging cable into your vape mod whenever it’s running low. 

However, you should make sure you stay with your mod while it’s charging. Internal batteries use Lithium Polymer, which can be pretty volatile. But internal batteries are commonly used in devices like phones and laptops, so they are safe for the average consumer to use. 

The main disadvantage of internal batteries besides the Lithium Polymer is that once your battery reaches the end of its life or fails, your vape mod is useless. 

On the other hand, external batteries don’t have these restrictions. They’re easier to deal with, and you can just slot them into a vape battery charger , but they still require you to familiarize yourself with some precautions. This leads us on to the second characteristic, which is particular to external batteries. 

If you have an external battery, then you’ll need to consider its protection status. If there is a circuit board attached to the base of your vape battery, consider it protected. This means it can’t be overcharged and won’t discharge inappropriately. 

When you see a vape mod manufacturer claiming that their vape mod is protected against short-circuiting, overcharging, and over-discharging, it will be the protective battery circuitry that’s the reason. The circuitry will make the battery a little larger too.

On the other hand, unprotected external vape batteries lack any circuitry, and you’ll have to be careful with them. Generally, you’ll get 3.7 volts out of these batteries and 4.2 volts when they’re completely charged. But you’ll need to keep the voltage charged above 3 volts and below 4.2 volts to avoid damaging the battery. Getting a safe charger is highly recommended.

There are four coding types used on vape batteries, and these are the following:

Different batteries have different combinations of these. There are three common combinations, and these are IMR, INR, and ICR. 

IMR batteries are Lithium Manganese. They discharge with a high current while at low temperatures . These batteries are typically safer than the other types.

INR batteries are Lithium Manganese Nickel. They are the best vape 18650 battery, and we’ll cover what those numbers mean shortly. They are simply IMR batteries with added nickel, which makes them hybrid batteries. Manganese reduces resistance, and nickel increases energy. The results are high-capacity batteries with a high current. They’re usually stable too.

Finally, ICR batteries are Lithium Cobalt. They provide more energy than any other best 18650 battery for vape options, but they’re also quite unstable. They don’t function well at high currents and often need to be external and protected. It’s best to avoid ICR batteries if you can. 

There are five sizes for vape batteries, and they’re not what you might think. Instead of sizes like small, medium, or large, you’ll see a series of numbers. These are:

The 20700 and 21700 batteries are more modern, but these are not commonly used yet. We’ve focused on the best vape 18650 battery choices in this article because these are the most frequently used, but we’ll still cover 20700 and 21700 batteries as they’re becoming more popular over time. 

The first two numbers in the 5-digit code are the width of the battery in millimeters, and the final three numbers are the length of the battery. That means the best 18650 battery for vape will measure 18mm wide and 65mm long.  

Its mAh rating shows the capacity of a vape battery, and its amp rating shows the currency. mAh stands for milliamp hours, and the higher this figure, the longer the life of your battery in between charges. 

The more milliamp hours there are, the lower the rate at which your battery will discharge. The discharge speed is the same as the amperage, which refers to the amount of power the battery can deliver at any one time. 

This means that if you see a battery with a high mAh rating and a low amperage, you should use it for vapes that have a lower wattage than others. To find batteries that suit high-wattage vape mods , simply look for low mAh ratings and high amperage ratings. 

You mustn’t exceed the amperage because doing so will exceed the limits of the battery and overload it. An example to help you is a 3000mAh and 3 amp battery. That means it can tolerate 3 Amps for 1 hour before it runs out.
 

Now that you know what you need to about the characteristics of vape batteries, it’s time to look at the best vape battery options we could find. We’ve picked out 3 products. One is the best vape 18650 battery, another is the best 20700 battery, and the final is the best 21700 battery. 

Each battery has been chosen because it has good customer reviews, plenty of product information, and few disadvantages. That way, if you choose one of the batteries below, you’re getting the best possible quality. 

This is the best 18650 battery for vape . Even the branding and the colors on this battery look great. You can pick from one of two options. A 35 amp and 3000mAh variant, or a 20 amp and 3500mAh variant. Both are equally good. 

Features include a voltage of up to 3.7V, alongside a steady current mode and a pulse mode that takes the battery to a slightly higher Amperage for a short time.  

This iJoy battery is a 20700 battery , making it one of the more modern choices available for vape mods. As the product name shows, its standard voltage is 3.7V, and its amperage is 40A. It’s available for $9.99, which is cheaper than the 18650 battery we just reviewed.

Features include a high-drain Lithium Nickel composition and a peak voltage of 4.2V. It also features a pulse mode that raises the amperage to 85A temporarily.  

Unlike the other batteries in this brief list, the Samsung option gives you 2 batteries instead of 1, for the price of only $14.99, which is a bargain. However, it’s a 21700 battery , which is one of the larger sizes on the market. 

Features include a 3000mAh capacity with an amperage of 35A. The steady voltage figure is 3.6V, and the peak voltage is 4.2V, similar to the previous battery we looked at. 

You should now know about the best battery for vape across three different battery sizes, meaning your vape mod should be covered. Hopefully, reading this has saved you time compared to looking through all the batteries you possibly could.

There are others available elsewhere, but we thought these three gave vapers the most valuable benefits and features, so that’s why we included them in this list. If you need to get more than one battery, it’s worth finding packs of these rather than buying them individually, as that will work out cheaper. 

If you want to find the best battery for vape and great deals for high-quality vaping equipment and accessories, there’s only one place to go.
