Understanding 21700 and 26650 Batteries:
The phrases "21700 vs 26650" and "26650 vs 21700" all refer to a direct comparison between these two types of lithium-ion batteries.
The numerical designations refer to the physical dimensions of the batteries:
21700: 21mm in diameter, 70mm in length.
26650: 26mm in diameter, 65mm in length.
Key Differences:
Size and Capacity:
While both are larger than the common 18650 battery, the 26650 is wider, and the 21700 is longer.
Generally, 26650 batteries tend to offer higher capacity than earlier 21700 models, but newer 21700 cells are closing this gap, and even surpassing some 26650 cells.
21700 cells are becoming more popular in newer high drain devices.
Energy Density:
Modern 21700 batteries often exhibit higher energy density compared to 26650 batteries.
This means that 21700 batteries can provide more energy per unit of volume, leading to more compact and efficient devices.
Applications:
High-power flashlights.
Industrial tools.
Some high drain electronic devices.
Electric vehicles (EVs).
High-performance flashlights.
Power tools.
21700 batteries are increasingly being used in:
26650 batteries are typically found in:
Key Considerations:
Application Requirements:
The choice between 21700 and 26650 batteries depends on the specific power and size requirements of the application.
Device Compatibility:
Ensure that the chosen battery type is compatible with the device or system in which it will be used.
Performance Needs:
Consider the needed amount of runtime, and power output that is needed for each individual application.
Availability:
21700 batteries are becoming more common in the market, and are being used by more and more manufactures.
Conclusion:
Both 21700 and 26650 lithium-ion batteries offer valuable power solutions, with their suitability depending on the specific application. Modern 21700 cells are becoming increasingly popular due to their higher energy density, and increased availability.
