UsageĪAA and AA batteries are used for portable devices commonly found in a house. The voltage generated by these batteries can be increased by multiple batteries end-to-end (in a series). Even larger batteries like the D batteries with a single cell have the same voltage of 1.5 volts. The similarity in their voltage is due to the fact that they are single-celled batteries. Why? Because the AA battery has more room and materials that allow it to produce more current.
However, an AA battery with the same composition as an AAA battery will generate more current.
For example, Lithium batteries generate more current than Alkaline batteries, and those generate more current than zinc-carbon batteries. The current generated by either an AA battery or an AAA battery depends on its chemistry and components. While both battery types have the same voltage of 1.5 volts, they generate different amounts of current. Therefore, in devices where only a small amount of power is needed, AAA batteries take precedence for their lightness and compactness. Space is often a luxury in portable devices, and we generally prefer lighter devices. The lesser components in AAA batteries also mean they are lighter. The larger size of AA batteries means they can carry larger components like electrolytes. This size is the most noticeable difference between the two. Size and WeightĪs we have mentioned, AA batteries are larger than AAA batteries. What is the Difference between AA & AAA Batteries?īelow are noticeable factors that differentiate AA batteries from AAA batteries. Triple-A batteries can also be stacked to increase their voltage to power more power-hungry appliances. Triple-A batteries are commonly used in remote controllers, toys, and digital cameras. However, alkaline batteries are still more sold because of their price-to-capacity value. Lithium AAA batteries have the highest capacity amongst the commonly available types. Like AA batteries, you can find AAA batteries with different capacities and longevity depending on the chemistry and components it works on. AAA batteries have a standard size of 1.75 inches in length and 0.41 inches in diameter. They are second to AA batteries in terms of popularity and can be observed to be physically smaller in size. What is an AAA Battery?ĪAA or triple-A batteries are other standards of batteries. Increased performance is generated by stacking multiple AA batteries together, increasing their voltage to power more power-intensive devices. In summary, the capacity of an AA battery depends on its internal chemistry. AA batteries with lithium, for instance, last much longer and deliver better performance than an alkaline battery that is more popular for everyday use. The longevity and performance of any given AA battery would last depending on the constituent of its cell. AA batteries measure between 1.94-1.99 inches in length (plus the button terminal on one end) and 0.53-0.57 in diameter.ĪA batteries are single-celled and weigh about 0.8 oz, on average. The term describes a standard battery size within a limited range of dimensions. They are the type you can expect to find in a random drawer and are also commonly used in toys and small appliances. These cylindrical batteries are the most common household batteries, made by all the popular brands, including Energizer, Duracell, and Panasonic. The high energy density is caused by the potassium hydroxide used in them.AA batteries are also known as double-A batteries.
