[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.
