Cola Battery with diet coke?

Question

Can you make a Cola Battery with diet coke? Also how many pennies for 1 aa battery?

Answer 1

Yep, but amount of copper effects the current not the voltage.  For voltage use multiple cells is serries.  But actually pennies are now copper and zinc

(inside) which might mess up the battery.  Scratch the edge of a penny and you can see the zinc.  If you put it in some HCl you can dissolve the zinc and make the penny hollow.

BUT (cause I'm a smart a__, an AA battery usually costs 50cents to dollar.
