What are the models of alkaline batteries?


Here are the common models of alkaline batteries, which are usually named according to international universal standards:

AA Alkaline Battery

Specifications: Diameter:14mm, height :50mm.

Applications: The most common model, widely used in small and medium-sized devices such as remote controls, flashlights, toys, and blood glucose meters. It’s the “versatile small battery” in daily life. For example, when you press a remote control, it’s often powered by an AA battery; flashlights rely on it for stable light; children’s toys keep running happily thanks to it; even blood glucose meters for health monitoring commonly use AA alkaline batteries to provide power for accurate measurements. It’s truly the “top choice” in the field of small and medium-sized devices.

AAA Alkaline Battery

Specifications: Diameter :10mm, height :44mm.

Applications: Slightly smaller than AA type, it’s suitable for low-power consumption devices. It shines in compact gadgets such as wireless mice, wireless keyboards, headphones, and small electronic instruments. When a wireless mouse glides flexibly on the desktop or a wireless keyboard types smoothly, an AAA battery often supports it silently; it’s also a “behind-the-scenes hero” for the melodious music from headphones.

LR14 C 1.5v Alkaline Battery

Specifications: Diameter approx. 26.2mm, height approx. 50mm.

Applications: With a robust shape, it excels at supplying high-current devices. It powers emergency lights that flash with strong light in critical moments, large flashlights that emit long-distance beams for outdoor adventures, and some electric tools that require substantial power during operation, ensuring efficient performance.

D LR20 1.5V Alkaline Battery

Specifications: The “bulky” model in alkaline batteries, with a diameter of approx. 34.2mm and a height of 61.5mm.

Applications: Commonly used in high-power devices. For example, it provides instant high energy for gas stove igniters to spark flames; it’s a stable power source for large radios to broadcast clear signals; and early electric tools relied on its strong power output to complete tasks.

6L61 9V battery Alkaline

Specifications: Rectangular structure, 9V voltage (composed of 6 series-connected LR61 button batteries).

Applications: Plays a key role in professional devices requiring higher voltage, such as multimeters for precise circuit parameter measurement, smoke alarms for safety monitoring, wireless microphones for clear sound transmission, and electronic keyboards for playing beautiful melodies.

Other special models:

  • AAAA type (No. 9 battery): An extremely thin cylindrical battery, mainly used in electronic cigarettes (enabling smooth use) and laser pointers (clearly indicating key points in teaching and presentations).
  • PP3 type: An early alias for 9V batteries, gradually replaced by the universal “9V” name as naming standards unified over time.
