The power behind the thick clouds lies within the batteries that fuel our devices. So, let's explore different battery options available for your device, learn why selecting the right one is important and uncover useful tips to extend the lifespan of your batteries for long-lasting vaping sessions.

What Is the Role of a Battery in E-cigarettes?

The battery is a component that provides the power necessary to heat the coil in the atomizer, which then vaporises the e-liquid. So, in other words, the battery is the source of energy that converts electrical power into heat to produce vapour.

E-cigarettes use different types of batteries, ranging from built-in rechargeable batteries to replaceable and rechargeable ones. The amp rating, capacity, and voltage of the battery can influence factors such as coil resistance, heating time, and overall performance of the device. Therefore, proper maintenance and handling of the battery are important for ensuring the safety and longevity of the entire e-cigarette.

What Are the Most Commonly Used Batteries in a Vape?

As mentioned above, there are different types of batteries that are considered safe and suitable for electronic vapes. However, the most common types are:

  • 18650 Batteries: This type of battery is popular in vape devices due to its high capacity and ability to handle high currents. That's why they are often used in regulated mods.
  • 20700 and 21700 Batteries: These newer battery sizes offer higher capacities and are able to handle higher currents compared to the 18650 batteries. For this reason, they are often used in more advanced vape mods for increased power and longer battery life.
  • Internal Lithium-ion Batteries: However, some vape devices come with already built-in rechargeable lithium-ion batteries. They can be perceived as more convenient as they do not require external battery purchases. However, their power may be limited compared to removable batteries.

In terms of power, the capabilities of these batteries can vary depending on factors such as capacity, voltage, and current rating. 

However, 18650 batteries typically range anywhere from around 2000mAh to 3000mAh with voltage outputs around 3.7V

20700 and 21700 batteries usually have higher capacities ranging from 3000mAh to 4000mAh or more, and can provide higher power outputs due to their larger size. 

Internal batteries vary in capacity and power output based on the specific device they are integrated into.

Can Classic AA Batteries Be Used in an E-cigarette?

Classic AA batteries should not be used in e-cigarettes for several reasons:

  1. Compatibility: These batteries are not designed to be used in e-cigarette devices because they require specially designed batteries that can handle the power demands and discharge rates specific to vaping.
  1. Voltage and Capacity: AA batteries typically have a voltage of only 1.5V, which is much lower than the voltage requirements of most e-cigarettes.
  1. Amperage Rating: E-cigarettes require batteries with specific amp ratings to safely provide power to the heating coil. AA batteries are not rated for the high discharge rates, which can lead to overheating or even safety hazards.
  1. Safety Concerns: Using incompatible batteries can pose serious safety risks, including the potential for battery leakage, overheating, or even explosion. Vape batteries have built-in safety features to prevent these issues.

Tips to Prolong the Life of Your Batteries

To ensure optimal performance and prolong the lifespan of your batteries, you can consider the following tips:

  • Always use the charger provided by the manufacturer or a reputable alternative that is compatible with your battery type. Avoid using generic chargers that may not provide the correct charging voltage or current, which can damage the battery.
  • Try not to charge your batteries for extended periods once they are fully charged. Overcharging can reduce the lifespan of the battery and may lead to safety issues.
  • Store your batteries in a cool, dry place away from direct sunlight and sources of heat. You can even use protective cases to prevent damage or short circuits if the battery comes into contact with metal objects.
  • Avoid exposing your batteries to extreme temperatures, both hot and cold. High temperatures can degrade the battery chemistry, while cold temperatures can affect performance. It is best to store your batteries at room temperature.
  • Make sure you are using the right type of battery for your specific vape device. Keep in mind that different devices have varying power requirements, therefore using the wrong type can lead to poor performance and potential safety risks.
  • Clean the battery contacts and threads of your device regularly to maintain good electrical connections. It's also recommended to check for any signs of damage on the battery and replace it when necessary.

How to Dispose of a Vape Battery?

Disposing of vape batteries in a correct way is important to prevent environmental harm and potential safety hazards. Vape batteries should not be thrown away in the regular household trash as they can contain hazardous materials. Instead, the safest way to dispose of vape batteries is to recycle them at designated recycling locations or through battery recycling programs. Many stores, recycling centres, or local authorities accept used batteries for safe and proper disposal.

    How Long Do Vape Batteries Last?

    The lifespan of vape batteries varies depending on how much you vape and how you take care of them. Generally speaking, a vape battery can last around 300-500 charge cycles before needing replacement.

    Are 21700 Batteries Better than 18650?

    21700 batteries typically offer higher capacities and discharge rates compared to 18650 batteries, making them better suited for high-power devices and longer vaping sessions. So, it's hard to say if they are better, but they are definitely stronger.

    Does 21700 Last Longer than 18650?

    Due to their larger size and higher capacity, 21700 batteries can last longer before needing to be recharged compared to 18650 batteries.

    Are Batteries in Vapes Safe?

    When used and maintained correctly, vape batteries are safe. However, it's crucial to follow proper battery handling and charging practices to prevent safety issues like overheating or short circuits.

    How Do I Know if My Batteries Are Bad?

    Signs of a poor battery include reduced capacity, shorter usage times, and any physical damage to the battery wrap. If you notice any unusual behaviour or performance, it may be time to replace it for a new one.
