![]() While button cells come in a variety of sizes, they all have one thing in common: they are significantly smaller than traditional batteries. A button cell is a small, cylindrical battery that is used in a variety of electronic devices. AAAA BatteryĬR2032 is one of the most popular button cell types. But some brands design these AAA batteries for high drain devices and are called Procell INTENSE Power batteries. The major applications include clocks, calculators, toys, cordless phones, TV remote controls, and other common household devices that require smaller cells. What are the applications of AAA batteries? The dimension may also slightly differ among these types. It includes the battery chemistries such as Alkaline, Lithium, Lithium Ion, NiCd, and NiMH batteries. These batteries have less capacity than AA batteries and are cheaper than AA batteries.ĪAA batteries are available in both primary and secondary categories. The AAA battery is 10.5mm in diameter and 44.5mm in length. The AAA batteries are smaller in size than AA batteries. ![]() What is the difference between AA and AAA battery? These are also common in stores and largely used in household devices. Like AA batteries, AAA batteries are also cylindrical. The other technical terms for AAA batteries include R03, AM4, MN2400, SP/out, mic, KR03, etc. AAA BatteryĬommonly known as Tripple-A batteries, AAA batteries are smaller in size than AA batteries. So they are the best choice for devices like clocks which are always on. These are long-lasting batteries and offer a longer shelf life. AA batteries are commonly used in small portable devices such as remote controls, toys, thermometers, calculators, hand sanitizers, etc. Where are AA batteries commonly used?ĪA batteries are mostly preferred for low-current drawing devices and thus utilize minimal energy. An AA battery is 14.5mm in diameter and 50.5mm in length. The letter A in an AA battery refers to the size of the battery. Must read: Important Battery Terms & Characteristics Explained (with Examples) What does A in an AA battery mean? These batteries produce a nominal voltage of 1.5V. But the dimensions may vary slightly based on the chemistry. Alkaline batteries, Lithium, Lithium Ion, NiCd, NiMH, and Carbon Zinc are available in AA dimensions. These are the most preferred battery size for household requirements and are thus widely available in almost all stores around us.īoth primary and secondary batteries are available in AA size. AA size battery comes in a cylindrical shape. It has some other technical names among which LR6 is the most popular. Note: For every specific size, the nominal voltage, capacity, and even dimensions slightly vary depending on the battery chemistry and manufacturing brand.ĪA batteries are also known as Double A batteries. Now let us discuss each cell in a bit more detail.

In this article, we will discuss different battery sizes and their applications. The battery sizes are standardized by IEC (International Electrotechnical Commission). ![]() Some of the popular battery sizes are AA, AAA, 9V, CR2032 (coin cell) ,etc. Batteries are available in numerous sizes and each one is designed to meet a specific purpose.
