AA batteries and AAA batteries are two commonly used types of batteries in daily life, but many people easily confuse these two types of batteries. In fact, AA and AAA batteries have differences in size, capacity, and application scenarios.
Size
AA batteries are much larger than AAA batteries, and visually, AA batteries are taller and thicker than AAA batteries. The diameter of a standard AA battery is approximately 14 millimeters and the height is approximately 50 millimeters; The diameter of AAA batteries is about 10 millimeters and the height is about 44 millimeters.
Capacity
Due to the larger volume and more discharge substances contained in AA batteries, they are usually able to provide greater capacity, which also means they can store more electricity and are more suitable for devices that require long-term power supply or high power consumption.
Identification
The battery model is usually marked on the outer shell of a standard battery, allowing you to quickly identify whether the battery is AA or AAA.
Application scenarios
AA batteries are commonly used in large and high power consuming electronic products such as electric toys, microphones, cameras, and smart locks.
AAA batteries are commonly used in electronic products with low power consumption, such as small remote controls, electronic scales, etc.
The voltage of AA batteries and AAA batteries is the same. Whether using disposable alkaline batteries or rechargeable batteries, when purchasing batteries, everyone should pay attention to the battery model required by electronic devices to avoid mixing AA and AAA batteries.
