AA batteries are one of the most common types of swappable power cells in circulation today. They’re what many of us typically picture when we think of the ‘classic’ size and shape for a standard replaceable battery.
Also known as “double A”, AA batteries are by far the most popular battery size. Used in a multitude of applications, these batteries can be purchased almost anywhere.
Double A batteries are generally what everyone pictures when they think of standard replaceable batteries. Used in everything from thermometers and staffing pagers to cordless phones, these batteries are used extensively. AA batteries measure at 1.5V, and work well for devices that require a somewhat high current draw, but are not in constant use. They can also be used for devices like clocks that are always on but use minimal energy.
Often used in single cell devices, or combined into pairs (or larger multiples) for powering larger but still relatively portable consumer electronics, AA batteries are incredibly versatile and very widely available almost everywhere in the world.
In this guide, we’ll give a rundown of numerous AA battery types, material variants and performance guidelines. We’ll also be looking at some common usage scenarios and frequently asked questions for AA batteries, to help clarify how to get the best from your cell-powered devices while continuing to use them safely and economically.
