· Dimensions:
The 21700 and 26650 battery cells are named based on their size. The 21700 cell has a length of 70mm and a diameter of 21mm, while the 26650 cell has a length of 65mm and a diameter of 26mm.
· Capacity:
· Voltage:
· Discharge Rate:
· Weight:
· Storage Temperature:
· Price:
In the selection of battery cells, price is also a factor to consider. In comparison, the price of a 26650 cell is generally lower than that of a 21700 cell, but prices may vary among different brands.
· Application Areas:
Due to the increased capacity and size, 21700 cells are well-suited for energy-dense portable electronic products such as cars and drones. On the other hand, 26650 cells, with their larger capacity, are suitable for portable devices in fields like electric tools, lighting, solar energy storage, communication devices, medical equipment, and military lighting, where more power or longer runtime is needed.
· Can a 26650 battery cell be used instead of a 21700 battery cell?
The compatibility of 26650 battery cells may not be ideal for some devices that require both high capacity and high discharge rates. In such cases, 21700 battery cells would be the better choice.
· How to Choose:
When selecting battery cells, consider the differences listed above between the 21700 and 26650 cells, and choose based on your specific needs and the compatibility of the battery with your device.
