AAA is smaller than AA and there are others not common on the market of different sizes and shapes. Why are batteries different sizes? Does it really make a difference regarding the function of a gadget? The AAA battery has the same voltage as the AAA.

Correction: The AA battery has the same voltage as the AAA.

It has to do with the battery's capacity to deliver power. While a AAA battery may deliver a certain amount of power for one minute before being exhausted, for example, a C battery may be able to deliver that same amount of power for five minutes before becoming exhausted.

Sizes Of Batteries

The capacity of a battery to store charge is often expressed in ampere hours (1 A·h = 3600 coulombs). If a battery can provide one ampere (1 A) of current (flow) for one hour, it has a capacity of 1 A·h. If it can provide 1 A for 100 hours, its capacity is 100 A·h.
The more electrolyte and electrode material in the cell, the greater the capacity of the cell. Thus a tiny AAA cell has much less capacity than a much larger D cell, even if both rely on the same chemical reactions (e.g. alkaline cells), which produce the same terminal voltage.

The voltage is the same but the life is not. Larger last longer. Smaller size was to make smaller devices. No one wants a tiny radio with a large D battery in it.
BTW: There used to be A and B batteries in the old days of portable radios with tubes.

AA vs AAA. Is for capacity, some gadgets require more wattage then others, thus you need a bigger reserve of juice.

It makes a difference in the size and weight of the gadget. Believe it or not, some people think a remote the size of a brick is too big.

The size is different to suit varoius applications. The voltage is the same.
