There are so many battery models and specifications, do you understand them?

Batteries play an important role in daily life. How to choose among the wide variety of battery types with wide applications? Let’s get to know the different battery models and specifications. The International Electrotechnical Commission (IEC) and the National Electrical Manufacturers Association (NEMA) respectively specify battery models, but the IEC and American National Standards Institute (ANSI) standards are not completely consistent. So how to distinguish battery models? Some battery model specifications are compiled below for your reference.

Batteries are divided into carbon batteries, alkaline batteries, nickel hydrogen batteries, lithium batteries, etc. according to their materials. According to the number of uses, they are divided into disposable batteries, rechargeable batteries, energy storage batteries, etc. Disposable batteries are the most widely used in daily life. Different countries and regions have distinguished and named batteries of different specifications according to their own characteristics. Long before relevant international organizations formulated standard models, most of these battery models were determined by manufacturers or relevant domestic departments. to name, thus forming different naming systems. The AAA, AA, C, D, N, F, SC and other marks seen on the battery body are all American model marks. In addition, the model representation method for lithium batteries is to use five digits (cylindrical type) or six digits (square type), such as 14500, 103450…

According to battery size specifications, the United States divides batteries into D, C, AA, AAA, N, and PP3. The corresponding IEC names are R20, R14, R6, R03, R1, and 6F22. In China, they are described as 1#, 2#, 5#, 7#, 8#, and 9v. Yes, the voltage of 6F22 is 9v, while the others mentioned above are 1.5v. In fact, the battery models are very rich and cannot be introduced one by one. For example, there are dozens of button battery models. We usually describe R6 batteries as AA batteries. AA is just a size description, not a complete battery model. The AA size may be an alkaline battery or a carbon battery, and of course it may be the size of a rechargeable battery. According to IEC standards, the complete battery model description should be: chemical properties + appearance + size, arranged in order.

Examples according to IEC standards are as follows:

Alkaline D battery has alkaline chemical properties, which is L; the shape is cylindrical R; the battery size is 20; so the complete IEC number is LR20.

If it is a carbon D battery, because the carbon is empty in the IEC number, the complete description is R20. LR6 is an alkaline AA battery, while R6 is a carbon AA battery, which can be clearly distinguished by the text on the battery casing.
