The primary difference between 18500 and 18650 batteries lies in their size and capacity. The 18650 battery measures 18mm in diameter and 65mm in length, while the 18500 battery is slightly shorter, measuring 18mm in diameter and 50mm in length. This size difference results in varying capacities, with 18650 batteries typically offering a higher capacity ranging from 2000mAh to 3500mAh, compared to the 18500’s capacity, which usually ranges from 1000mAh to 1600mAh.
Size Comparison Table
| Battery Type | Diameter (mm) | Length (mm) | Typical Capacity (mAh) |
|---|---|---|---|
| 18500 | 18 | 50 | 1000 – 1600 |
| 18650 | 18 | 65 | 2000 – 3500 |
Applications
Both battery types are popular in various applications, but their size and capacity make them suitable for different uses:
- 18650 Batteries: Commonly used in high-drain devices like laptops, electric vehicles, and power tools due to their higher capacity.
- 18500 Batteries: Often found in smaller devices where space is limited, such as compact flashlights, portable electronics, and some vaping devices.
