The 14500 battery is often compared to the AA battery due to its similar size and shape. However, they are not the same. The 14500 is a lithium-ion rechargeable battery with a nominal voltage of 3.7V, while a standard AA battery (alkaline) has a nominal voltage of 1.5V. This difference in voltage and chemistry affects their applications and performance.
Understanding the Differences Between 14500 and AA Batteries
To fully grasp the distinctions between these two battery types, we must consider several key factors: size, voltage, chemistry, and applications.
Size and Dimensions
Both batteries share a cylindrical shape, but their specifications vary slightly:
| Battery Type | Diameter | Height |
|---|---|---|
| 14500 | 14 mm | 50 mm |
| AA | 14.5 mm | 50.5 mm |
Though their dimensions are nearly identical, the slight differences can affect compatibility in specific devices.
Voltage and Chemistry
- 14500 Battery:
- Voltage: 3.7V
- Chemistry: Lithium-ion
- AA Battery:
- Voltage: 1.5V
- Chemistry: Alkaline or NiMH (rechargeable)
The higher voltage of the 14500 makes it unsuitable for devices designed specifically for AA batteries, which could lead to damage or malfunction.
Latest News
