Vape Batteries

With the UK’s ban on disposable vapes now in effect, more vapers are turning to reusable vape kits, including pod systems and advanced mods. A key component of many of these devices — especially external battery mods — is the vape battery.

Choosing the right battery is essential not just for performance, but also for safety and longevity. Whether you’re using a single-cell mod, dual-battery device, or a mech mod (for experienced users only), understanding vape battery types and care is crucial.

What Are Vape Batteries?

Vape batteries are high-drain lithium-ion cells specifically designed to handle the power demands of vaping. Some kits come with built-in batteries (charged via USB), while others require removable batteries — usually 18650, 20700, or 21700 cells — for increased capacity and flexibility.

These are not the same as household batteries. They’re designed for rapid discharge and high current output, making them suitable for sub-ohm and variable-wattage vaping.

Types of Vape Batteries

🔋 1. Internal (Built-In) Batteries

Many beginner-friendly vape kits — especially pod systems — feature built-in batteries that charge via USB-C or micro-USB.

Features:

  • No battery handling required

  • Common in closed and open pod kits
