What is The difference between AAA and D batteries?
The main difference between a AAA and a D battery is the size. With the size, you can put more charge holding materials, such as Lithium-Ion, Ni-Cad, etc. They both have the same voltage output, but the D battery can hold more charge. Since electronic devices “pull” charge from the batteries, the D battery will last longer comparitively to a AAA battery in a similar device. This is why you see AAA batteries used in small devices, that have low current draw, and D batteries are used in items that require more power, such as boom boxes, and such.
