Without thinking about the calculations, I can tell you that your result is
a lot different than reality. A typical Nickel-Metal-Hydride rechargeable
AA cell (which is considerably more energy than a AA alkaline cell) is
about
2 amp hours, and it is perhaps as big as 5 sugar cubes. Therefore, your
result is off by at least 50-fold.

Subject: [Phys-l] How much energy can a battery discharge
How much energy can a Battery Hold? Can I just divide grams-moles by_______________________________________________
Coulumbs?
1 Coulumb = 6.2 x 10^18 electrons or 1 A / sec
Avogadro's number = 6.02 x 10^23 gram-moles
Coulumbs for a gram-mole = 6.02*10^23 / (6.2*10^18)
= 97096.77419
Divide by 60*60 to get amp hours = 26.97132616
Therefore something the size or mass of a sugar cube, could give about
27 amp hours on the negative terminal.
