Vape batteries - A quick guide

What is a vape battery?

A vape battery is a replaceable cell that fits inside your mod. These batteries look the same to ordinary batteries like AA or AAA, however you won't find them in convenience stores. Most of these cells are often used in packs inside laptops, electric scooters and even electric cars. Their main feature is that they can store a lot of energy with respect to their size and this makes them popular for various industries.

Not to be confused with a vaporizer pen battery, which is a built-in cell that cannot be replaced.

Which are the most common vape batteries?

The 18650 battery is the most commonly used cell for both box mods and tubular mods. Older device used to work with smaller 18350 batteries, however these are not as popular nowadays.

Other commonly used vape batteries include bigger models like 20700, 21700, and 26650. These have higher capacities and discharge rates when compared to the ordinary 18650 and they offer better battery life.

What battery should I get for my mod?

When shopping for a good vape battery it's important to know which types of cells are compatible with your device. In the case of 18650 mods, these will only work with 18650 batteries. Mods that take bigger batteries like 20700, 21700 or 26650 may come with an adapter for 18650 cells. However, this is not always the case and you should always check the manual and specifications of your vape before purchasing batteries.

Do I really need an external charger for my batteries?

Most electronic box mods will recharge your batteries when connected to a wall adapter or an USB port. And while these will do a decent job most of the time, they don't offer the stability and performance of a dedicated vape charger. The charger will use specific current depending on the type of battery and it will help preserve its lifespan and peak power for much longer.

But even if you use a charger these cells won't last forever. Each unit has a limited number of recharge cycles - usually over 300 - after which it won't be able to store the same amount of energy. This is why if you notice a drop in performance and autonomy, it's probably time to replace vape batteries.
