AA and AAA batteries are the most common types of batteries used in daily life and can also be categorized as AA and AAA lithium batteries, which are sometimes easily confused. What is the model number for AA batteries? What about AAA batteries? What are the size specifications for AA batteries? And for AAA batteries? Let’s take a look at what the model numbers for AA and AAA batteries are and what AAA batteries mean.
The AA battery (also known as R6) is one of the battery models, typically characterized by a diameter of 14 millimeters (mm) and a height of 50 millimeters. Due to its small size and moderate electric capacity, the AA battery is widely used in a variety of household appliances and digital electronic products. The AA batteries available on the market include nickel-metal hydride rechargeable batteries, nickel-cadmium rechargeable batteries, alkaline zinc-manganese batteries (commonly referred to as “dry batteries”), and common acidic zinc-manganese batteries (commonly referred to as “traditional batteries”). You can understand the basic performance of the AA battery by looking at the English letters marked on the battery, which helps to determine what kind of battery to use in what device.
The AAA battery is a standard for dry batteries in the United States, compatible with the model number for batteries in China or Taiwan. The battery is cylindrical, 43.6 millimeters in height and 10.1 millimeters in diameter. It is a common battery, smaller than the AA battery. It is commonly used in small-sized electronic devices that consume less power, such as MP3 players, small smart remote controls, etc. There are disposable dry batteries, as well as rechargeable nickel-metal hydride and lithium batteries.
The difference between AA and AAA batteries:
1. AA is commonly referred to as the model for these batteries, typically with size specifications of: 14 millimeters in diameter and 49 millimeters in height.
2. AAA is commonly referred to as the model for these batteries, typically with size specifications of: 11 millimeters in diameter and 44 millimeters in height.
3. The size of the AA battery and the AAA battery is different. The typical size specifications for the AA battery are 14 millimeters in diameter and 49 millimeters in height. The AAA battery is slightly smaller than the AA battery, with size specifications of 11 millimeters in diameter and 44 millimeters in height. People can easily see the big difference between the two from the appearance of the battery.
Size specifications for AA and AAA batteries:
1. The AAA battery model is relatively common, typically used in MP3s, with a standard AAA battery height of 43.6±0.5mm and a diameter of 10.1±0.2mm.
2. The AA battery model is even more obvious, used in digital camcorders, electric toy cars, etc., with a standard AA battery height of 48.0±0.5mm and a diameter of 14.1±0.2mm.
Scope of application for AA and AAA batteries:
The AAA battery is a common battery, smaller than the AA battery. It is commonly used in small-sized electronic devices with low power consumption, such as MP3 players, small smart remote controls, etc. There are disposable dry batteries, as well as rechargeable nickel-metal hydride and lithium batteries.
