Internal Battery

What exactly sets internal battery vapes apart from their external battery counterparts? To give you the answers, let's explore what they are, what the key differences between internal and external batteries are, and weigh the pros and cons of opting for a device with a built-in battery. Whether you're a newbie or a seasoned vaper, find out if internal battery vapes are the perfect fit for your vaping lifestyle.

What Is Internal Battery on a Vape?

Internal battery, also known as a built-in battery, refers to a rechargeable power source that is integral to the device and cannot be removed or replaced by the user. This type of battery is commonly found in compact and pod systems or disposable vapes, as well as some beginner and intermediate level vaping devices. These built-in batteries are designed to be charged directly within the device, offering convenience and simplicity for vapers on the go. 

You should always charge your batteries with an appropriate charger and charging cable. It is also recommended to recharge your batteries after they run out and try not to overcharge them. These simple tips can prolong the lifespan of your battery.

Key Differences between Internal and External Batteries

Internal Battery:

  • Built-in rechargeable power source within the device
  • Cannot be removed or replaced by the user
  • Convenient for on-the-go charging
  • Typically found in compact and beginner-level vaping devices

External Battery:

  • Removable and replaceable power source
  • Requires separate charging unit
  • Offers flexibility to carry spare batteries for extended use
  • Commonly used in more advanced and high-powered devices

Benefits and Drawbacks of Internal Batteries

The benefits include:

  • Convenient Charging: Internal batteries allow for direct charging within the device, eliminating the need for separate charging units or removable batteries. To charge a device with an internal battery, you simply need to connect it to your charging cable until it is fully charged.
  • User-Friendly: They are easy to use and maintain, making them ideal for beginners or vapers who prefer a hassle-free vaping experience. The only thing you need to do is remember to charge them when necessary.
  • Portability: These batteries are more commonly used with lower-powered devices that are also smaller and more compact compared to the more advanced ones. This allows the battery to be smaller and lighter, making them ideal for people on the go.
  • Safety: Built-in batteries are typically designed with safety features to prevent overcharging, overheating, and short circuits, providing peace of mind to users.

On the other hand, internal batteries also have their fair share of cons such as:

  • Limited Lifespan: The lifespan of these batteries is one of their cons as they will eventually lose their capacity over time, requiring you to replace the entire device.
  • Restricted Use: Users cannot easily swap out depleted batteries for freshly charged ones. This means that when your battery runs out, you need to wait until it is recharged again.
  • Environmental Impact: When internal batteries reach the end of their lifespan, the entire device must be disposed of, contributing to electronic waste. If you want to know more about responsibly recycling your device, make sure to check out this article where we dive deeper into this topic.
