Vape batteries come in a myriad of styles and should be chosen with care to ensure you are using the proper one for your vaporizer. Different vaporizers have different power requirements, and using the wrong type of battery can pose safety risks.
The most common e-cig rechargeable batteries are those that form the base of an e-cig such as the eGo Battery 650mAh. A 510-threaded compatible atomizer or clearomizer is attached to the battery for vaping e-juices. More advanced is the box-mod battery, which is used in mods to power a sub-tank. You can even purchase a variable voltage e-cig battery for use in more sophisticated sub-ohm rigs.
The best vaporizer battery will typically be composed of IMR chemistry, which is widely regarded as the safest battery chemistry for vaping. These batteries are less likely to fail and vent, making them a safer choice. Batteries are also rated in terms of mAh or milliampere hours. The higher the mAh rating, the longer the battery will last.
