A double AA battery, also known as an AA battery, is a standard-sized single-cell cylindrical dry battery commonly used in many portable electronic devices. According to the IEC 60086 system, it is designated as size R6, while ANSI C18 refers to it as size 15.
Key Characteristics of AA Batteries
Here's a breakdown of the key characteristics:
-
Size and Shape: Cylindrical, with standardized dimensions to fit various devices.
-
Type: Single-cell dry battery, meaning it produces electricity through a chemical reaction within a sealed container.
-
Standardization: Designated as R6 by IEC 60086 and 15 by ANSI C18, ensuring compatibility across different manufacturers and devices.
Common Uses
AA batteries are ubiquitous and used in a wide array of devices, including:
- Remote controls
- Flashlights
- Toys
- Portable gaming devices
- Clocks
- Digital cameras
- Wireless keyboards and mice
Technical Specifications
| Specification | Value |
|---|---|
| IEC Designation | R6 |
| ANSI Designation | 15 |
| Shape | Cylindrical |
| Chemistry | Varies (Alkaline, Lithium, Ni-MH, etc.) |
Battery Chemistry Options
AA batteries are available in various chemistries, each offering different characteristics in terms of voltage, capacity, and performance. The most common types include:
- Alkaline: Provide good general-purpose performance and are relatively inexpensive.
- Lithium: Offer higher energy density, longer shelf life, and better performance in extreme temperatures.
- Nickel-Metal Hydride (Ni-MH): Rechargeable and environmentally friendly.
