Vape Batteries

Shop high-quality 18650 and 21700 vape batteries from top brands Molicell and Avatar. These rechargeable batteries are specifically designed for use with replaceable battery vape mods, and can be charged either in your device or with an external battery charger such as the Nitecore I2 Charger. Before purchasing, ensure that your battery is compatible with your device. For devices that work with either 18650 or 21700 options, we recommend choosing 21700s for a longer battery life.

What are replaceable vape mod batteries?

These lithium-ion batteries are designed for use with vape mods and pod mods that use external batteries. Typically coming in 18650 or 21700 options, they are commonly used for more advanced and powerful vape devices.

The pros of using a replaceable vape battery

1. You can have a second battery charged and ready - so when your device runs out of juice, you can quickly switch over to a new one.

2. If you have a problem with your battery, you can continue using your mod device. This is far more economical than replacing the whole device!

3. Many mods that use replaceable batteries have a larger capacity, meaning you can keep vaping for longer.

What do the numbers mean?

The first and second numbers refer to the battery’s diameter and the second two numbers to the length. For example, an 18650 battery is 18mm in diameter and 65 mm in length. The 0 at the end refers to the fact it is a cylindrical shape.

Which is better, 18650 or 21700 batteries?

We find that most people prefer 21700 batteries, as they last longer and are only slightly heavier than 18650s. However, if weight is important to you, you might want to choose to get the slightly lighter 18650s.
