The diameter of the 21700 battery is 21mm. To be more precise, it has an approximate length of 70mm and an approximate diameter is 21mm but technically 21700 cell size is allowed with some tolerance in length and diameter. Thus you could find specifications written as (say) 21 ± 0.41mm ✖ 70 ± 0.25mm on the datasheet and features of the li-ion cell.
This increase in size allows the 21700 to deliver higher energy storage and improved performance. The larger size of the 21700 cell enables it to store more energy, making it ideal for applications requiring high power capacity, such as electric vehicles and industrial battery packs.
One of the standout features of the 21700 is its higher capacity and energy density compared to smaller batteries. This allows it to power larger devices, such as electric vehicles and solar energy storage systems, with more reliable performance and fewer recharges. As mentioned earlier, the 21700 battery is 21mm in diameter and 70mm in length.
The 21700 battery operates at a nominal voltage of 3.7V, with a full charge voltage of 4.2V and a discharge cutoff voltage of 3.0V. This voltage range aligns with industry standards for lithium-ion batteries, ensuring compatibility with various devices and systems.
