E-Cigarette Batteries

A vape unit is made up of different components such as a battery, tank, coil, drip tip, and E-liquid. Each element is essential, but the vape battery serves as the heart of it. The battery supplies power to the vape, allowing it to correctly function and fulfil your vape needs. The E-cig batteries are designed for beginners and intermediate vapers, featuring mainly built-in batteries. Advanced vape mods usually feature a battery body and use one or more high drain batteries.

If you are beginning to vape and are confused on what vape battery to use for your vaping needs, don’t worry because Flawless Vape Shop is here to help. We offer a wide variety of vape battery selections that we guarantee to have high quality and has passed a high standard screening just for you. ...

Types of Batteries

Built-In or Removable Batteries

There are two types of vape batteries namely, the internal (built-in) and external (removable) batteries. It's quite easy to differentiate between the two. Internal batteries are those that come alongside your unit or mod when having purchased them, while the external Batteries are those bought from the store separately.

What are External batteries and why use them?

Vape batteries, like in any other electronic devices, wear out as you continuously use them. As time goes by, you'll notice that your internal battery life becomes smaller and smaller. Imagine this, after charging your mod, you'll use it of course, but only after a few minutes of use, the battery is low again! Frustrating, right? Flawless Vape Shop UK offers a wide variety of external vape batteries to avoid such frustrating moments.

External batteries have many advantages over the internal ones. They are more flexible as you have a variety of choices to choose from. You can even buy spare vape batteries, so when the battery you are using gets low, you can easily take them out and use them! This way, you can enjoy quality vape without any interruptions.

External Batteries Basics: Sizes

The size is another essential characteristic of the battery. The standard cells used for vaping are called “18650” batteries. This can be broken down into two essential parts: 18 and 65. The 18 tells you the diameter of the battery in mm, and the 65 shows you the length of the battery, 65 mm. Therefore, an 18650 vape battery is 18 mm in diameter and 65 mm tall.

Be sure to look up your battery type to order the correct size of batteries. But whatever they are, be it 18650, 20700 or maybe even a 21700 battery, we at the Flawless Vape Shop UK have got them for you.

What Vape Battery should I use in my mod?

As mentioned, there are 2 types of vape batteries: built-in and removable. Here is the comprehensive guide of the pros and cons of internal battery vs. removable battery mods.

With internal batteries, there’s very little to worry about. You just charge, using the supplied charging cable, and vape. It’s recommended to charge until the battery is at full capacity but not essential if you’re in a rush. The biggest disadvantage of using mod with an internal battery is that once the vape battery is no longer chargeable or breaks, the mod becomes useless.

External batteries, on the other hand, are a completely different ball game. You can choose your own batteries to level up and customize your vaping experience. Do you prefer big coils and high-wattage vaping? You’ll want batteries with high continuous discharge ratings. Are your requirements for vapor production more modest? Choose batteries with high mAh ratings for more vaping time.

Another advantage in using a removable battery for your vape mod is that you will have a less downtime. If you have more than a pair of batteries, you can just simply use the other pair of batteries while the other one is charging. This is also good if you travel a lot because having pairs of batteries means you'll have limited access to power while on the trip.

How long do vape batteries last?

The battery life will depend on how often you use the device, but a full charge will last approximately 300 puffs. We suggest replacing your battery after 1 year of usage.

What Batteries are Used in Vape Mods?

There are several lithium batteries on the market today but only a few suitable for vaping safely.There are batteries used in other electronic devices, like power tools, flashlights, lanterns, laptops, radios, electric bikes, and even electric cars that are the same types with vape batteries but the batteries from these devices should not be used with your vape mods.

The most distinguishable feature between vaping battery types is size. These are the most common battery sizes used in vaping:

  • 18650
  • 20700
  • 21700
  • 26650
  • Check your vape manuals to see what battery type is used to your vape mods.

    Other Things to Consider

    20700 and 21700 batteries are larger and of a higher capacity than most 18650 chargers. But fear not, Flawless Vape Shop has got you covered! We offer brands like Nitecore i4 which can charge up to 4 vape batteries of 18650, 20700, and 21700. But if you are looking for the best 18650 battery charger, Efest is the one for you.

    A Friendly Reminder from Flawless Vape Shop

    Upon buying external batteries, make sure that you "marry" them. Vapers are now following a trend to "marry" their external batteries. This means always using a pair of vape batteries at the same time. For example, you have four batteries; you group them into two sets; set A and set B. You must make sure that you won't use a battery from the set A with the battery from the set B as the mod drains them both at the same speed.

    If one battery is old and the other is brand new, the older battery won’t respond as well as the newer one, and probably won’t hold a charge as well either. Here, one battery is put under more stress than the other, hence does more work. One of the vape batteries may be more depleted than the other, however as its partner shares some of the load, the mod will still fire, but you’ll still be asking for a lot from the nearly-drained battery.
