Coleco Perma Power C Batteries

[Porksta]

I found four of the Coleco C Perma Power Batteries, with adaptor. They are in great shape. They go with the little mini arcade games that Coleco made in the 80's. Any idea on their value?

They also were used with the Colecovision driving module. Rarely do I see them without one of the mini arcades or the driving module so you're guess is as good as mine. However when they are bundled with the above they tend to add about $10-$15.
