In the ever-evolving world of vaping, the choice of battery can significantly impact your experience. Among the various options available, the 21700 battery has emerged as a popular choice due to its larger size and increased capacity. This comprehensive guide will explore everything you need to know about 21700 batteries for vaping, including their features, top picks, and essential safety tips.
The 21700 battery is a popular choice for vaping due to its size (21mm x 70mm) and high capacity (3000-5000mAh). This means longer usage times without frequent recharging, making it ideal for high-drain devices like vaporizers.
Understanding 21700 Batteries
The name “21700” refers to the battery’s dimensions: 21mm in diameter and 70mm in length. This larger size allows for a higher capacity compared to the commonly used 18650 batteries, which measure 18mm by 65mm. The increased capacity translates to longer vaping sessions without frequent recharges.
Key Specifications
- Capacity (mAh): The amount of energy a battery can store. Higher capacity means longer usage times.
- Continuous Discharge Rate (CDR): The maximum current at which the battery can be safely discharged continuously. This is crucial for high-wattage devices.
- Battery Chemistry: The type of chemical composition used in the battery affects its stability and safety.
Advantages of 21700 Batteries for Vaping
- Higher Capacity: Most 21700 batteries range from 3000mAh to 5000mAh, allowing for extended use between charges.
