Does it really need to be D cells or C cells? Why not a gell cell?
Have you looked at car "battery booster" units?

Why not just go to Radio Shack, buy 2 4-cell battery holders (or 4
2-cell ones), wire them together to get 12 volts, mount them in a box or
case.
Radio Shack probably has the cigarette plug too.
Maybe Im missing something here, but this seems like an extremly simple
project?
If you dont have access to radio shack, check out this website:

I havent looked yet, but Im sure they will have the parts you need.
