I am just curious - can anybody maybe tell me

Hi All

They say that there is an enormous amount of energy stored in a drop of
water. How much energy is stored in a AAA battery? We know that one AAA
battery generate a light for several minutes or even hours... is that "all"
the energy stored in that one battery, or is this due to the fact that there
are much more energy in the battery, but that its utilization is
inefficient. E = MC2, but the mass of the battery is not the energy in the
battery.

The question is, if the energy in one AAA battery is utilized to its full
potential and with maximum efficiency, how much energy is in one AAA
battery?

Sorry for such a stupid question.

Thanks
Anton

The solution is in the rated "mAh" guide on the battery casing.
(mAh = milli-Amperes per hour)

Make that milliamp-hours. ...as in milliamps *TIMES* hours, not
milliamps divided by hours.

And that ain't much.

E.g.: 1000 mA hour cell with one volt would produce 1/1000 KWH. If you
pay $.10/KWH, this "cell" would produce 1/100 $.01.

A "typical" cell might produce 3 or 4 Watt Hours of energey. But still
only a fraction of a cent.

You describe the energy in a drop of water as enormous,
and it is in terms of E=MC^2. But in terms of chemical
energy, which is how the energy is stored in the AAA
cell in your reference, the drop of water is inert - there
is little or no stored enrgy. So the comparison is
meaningless. Can you explain what you have in mind
with respect to the drop of water?

In common terms, the energy storage capability of an AAA
cell is poor.

The energy released from a battery is released from a chemical reaction. The
chemical bonds between the chemicals in the battery are broken, new bonds
are formed, creating a new chemical, and a release of electrons. The battery
does not directly convert mass to energy.
