why are there different sized batteries (aaa-D, etc) if they all put out the same 1.5v?
In: 394
I was upset when i worked for RadioShack; we sold 28-volt batteries and 28-volt bulbs but no holder for the battery

It will blow your mind when you open up the 6V lantern batteries (that are 4×1.5v cells in series)
Or 9v battery that is 6×1.5v button cells
Or 6v/12v remote batteries that are also a combination of smaller batteries.
The voltage comes from battery chemistry, and then they just put them togrther in series to make the required voltage.

A bigger battery won’t fit in smaller device, and a smaller battery won’t provide as much power for as long as a bigger one.
Or with bigger words: Energy storage capacity (Watt-hours) is affected is mainly by size, whereas potential (voltage) is affected mainly by battery chemistry (e.g. Alkaline 1.5V, NiMH 1.2V, LiPO 3.7V etc.)

Try thinking of the battery and the electricity as a watering can with water in it. The holes in the spout of the watering can are a specific size, and when you pour out the water, it comes out at a specific rate because of how big the holes are. Now imagine you make the can bigger, but the holes remain the same. Now you are still putting out the same rate of water (the voltage) but you have more water, so you can use it a lot longer.

Older chemistry before alkaline were pretty weak, so the only way to get a decent current from a cell was to make it bigger.
Now days you can get adapters to let you put an AA or 2 inside a plastic D cell sized thing to let you use cheaper or more convenient cells in things. They work fine if you use alkaline cells in something that only takes Ds because they expected people to use junk cells in it like big heavy flashlights etc.
