10. Same size, same voltage, different capacities

The bigger the battery the more juice it holds (composition being equal, of course).

They're all the same diameter but different thicknesses, and thus contain different amounts of energy.



However, when you stack batteries positive-to-negative, you add the voltages. Just like in a flashlight... two "D" batteries end-to-end deliver 3 volts to the bulb, even though each battery only delivers 1.5 volts.

If you stick 2 thin 3-volt batteries end-to-end, you get six volts... which would really suck if your device was designed to run on only 3 volts.



If you need to put a thinner battery in a slot designed for a thicker battery, don't double them up... stick a penny or something in there to build up the thickness without adding voltage.
