A cartridge battery, also known as a vape battery or e-cigarette battery, is a rechargeable device that powers a vaporizer or e-cigarette. It is the component that provides energy to heat the heating element (atomizer) in the vape cartridge, which in turn vaporizes the e-liquid for inhalation.
Cartridge batteries come in a wide range of sizes, capacities, and voltages, and can be designed for use with specific types of vape cartridges. Some cartridge batteries are designed to be used with disposable cartridges, while others are designed to be used with refillable cartridges.
When choosing a cartridge battery, it's important to consider factors such as the compatibility with your vape cartridge, the battery capacity, the voltage output, and the overall size and design of the device. You may also want to consider the battery life, charging time, and the ease of use of the device.
