The 18650 and 21700 batteries vary not only in dimensions but also in their functionalities. The 18650 battery is 18mm in diameter and 65mm in length, while the 21700 battery measures 21mm in diameter and 70mm in length. This size difference translates to the 21700 battery generally having a higher capacity and energy density, which can lead to longer usage times between charges. Users report that the added capacity of the 21700 allows for more extended periods of use in high-drain devices, thus making it a preferred choice for those needing consistent power output.

However, the increased capacity comes with a trade-off. The 21700 battery typically weighs more than the 18650 battery, which can affect the design and usability of portable devices. For instance, in vaping, users have noted that while the 21700 offers more power, the added weight can make devices feel bulkier and less manageable, especially for those who prioritize portability. This highlights the importance of weighing the benefits of increased battery life against the impact of extra weight on the overall user experience.

In terms of pros and cons, the 18650 battery stands out with its lightweight design, making it ideal for compact applications. It is often favored for devices where portability is crucial, despite having a lower capacity compared to the 21700. On the downside, users often find themselves recharging more frequently, which can be inconvenient for high-consumption uses. The 21700, although heavier, compensates for its weight with superior performance in energy retention and longevity, which is especially appealing for devices that require sustained power, such as electric bikes or power tools.
