Features of a Fenix AA battery-powered flashlight

Advantages

AA batteries offer several advantages when used in Fenix flashlights:

  • Global availability: AA batteries are widely available, making them ideal for travellers and users in remote areas.
  • Cost-effective: They are less expensive than specialised batteries and are available in both rechargeable and disposable versions.
  • Flexibility: Fenix flashlights that run on AA batteries can be used with both rechargeable and disposable batteries, giving users more freedom of choice.
  • Reliable performance: AA batteries offer a good balance between runtime and power, essential for effective lighting in a variety of situations.

Disadvantages

Although AA batteries are popular for use in Fenix flashlights, they also have some disadvantages:

  • Limited energy capacity: AA batteries have a lower energy capacity compared to batteries such as 18650 or 21700, resulting in shorter usage time per charge or replacement.
  • Less powerful output: They may not provide the high current required for the most powerful flashlight models, which can limit brightness and functionality.
  • Frequent replacement required: For intensive use, AA batteries need to be replaced more often, which can be inconvenient and expensive over time.

Difference between AAA and AA batteries

AAA and AA batteries differ mainly in size, capacity and energy supply:

  • Size: AA batteries are larger and thicker than AAA batteries.
  • Capacity: AA batteries have a higher capacity, which means they last longer and are suitable for more energy-intensive devices.
  • Energy: AA batteries provide more power, while AAA batteries are more often used in lighter devices.

These characteristics determine their application.
